Best positions to install a CCTV camera for office security

The selection of CCTV camera positions is the important element to acquire the better results from surveillance system. Investigation and deterrence are the basic two reasons to install the CCTV cameras in the office. If your surveillance system is able to provide you with clear image and sequence of the incident, you have achieved the objective of installing the CCTV camera. In this connection, you need to choose the proper locations to install the cameras in your office.

How to choose the best locations for CCTV camera?

The clear image is helpful to identify the person or persons involved in any crime. Moreover, the recording of the evidence provide lot of information to reach any conclusion. To achieve these to objective, the following general principles focused while installing CCTV cameras.

  • On main static points, the cameras must be closer to the object so that it may capture the clear and identifiable image.
  • On wider location where you monitor the activity of objective, the cams must be installed on wider angles.

Best 5 location you may select to install CCTV cameras in your office 

Keeping in view the above-mentioned principles, the following locations are recommended for CCTV camera. 

1.Entry point:

Entry point of the office or building is the first location that can provide the best image of the objective. At entry point, everyone takes time to look at and open the door. The image or video taken from this point is more helpful to identify the person. At entry point, the CCTV camera must be installed at closer location. The best recommended distance is about 3-4 feet from the average height of human being. 

2.On office reception or counter:

The office reception or counter is the next important location to be covered with CCTV camera. This location also provides with clear identifiable image of the objective. Depending upon the size and location of reception counter, you can install one close (low level) and a wider rage camera. If we see on the crime scenes happening worldwide, we can analyze that most of the crimes are occur on cash counters. Therefore, this location needs more attention while selecting the locations for CCTV cameras.

3.Staffroom or working area:

Staffroom and working area are the important locations to be covered with CCTV cameras. The surveillance system is an unblinking eye on the work place to monitor the activity. The security system helps you to know the entry of unauthorized persons in the work place. Moreover, CCTV camera has made it easy for the boss to monitor his/her workers and staff in the office. Now you can monitor the activities of your staff through a television screen. CCTV camera also works as supervisor in the office. 

4.Blind corners and stores:

For more security and surveillance, the blind corners and stores of the office building need to be covered with CCTV cameras. At these hidden locations, wide-angle cameras are best recommended because you can cover the more area with the camera installed at distant location.

5.Parking area and garages:

The parking area and garages adjacent to your office also need surveillance. Although, the parking area needs both close and wide-angle cameras; however, usually, wide-angle cameras are installed on these locations. Depending upon the location, if the space and budget allow, install CCTV camera at close as well as distant locations to identify the objective and to record the sequence of incident or crime.

Uses of CCTV cameras in Singapore Other than Crime Prevention

The primary use of CCTV Camera in Singapore and many other parts of the world is crime prevention. There are many proven reports which show that CCTV camera placement leads to the reduction of crime rate in the area. Although, initially, it was the only known use of this device but with time, people have learned its diverse uses. Now it is being used in many different ways.

Suggested Uses of CCTVcameras in Singapore

Here given are some uses of CCTV cameras other than crime prevention:

Traffic Monitoring:

CCTV cameras are being used in the monitoring of traffic in many cities. Their prime function on the roads is to capture any accident or mayhem. They are not used as the speed cameras. 

Observing Industrial Processes:

Many industrial processes are highly dangerous for humans, especially in chemical industry but their monitoring is vital for flawless continuation of the procedure. These industries use CCTV camera to observe those processes. 

Employees Monitoring:

Nowadays, many organizations take the help of CCTV to check the activity of the employees. As all the actions are being recorded, workers remain focused on the work. Employers usually set CCTV camera to scan goods and their quantity, quality control, absence and presence of the worker and so much more. Occurrence of specific event can be recalled when in need. 

Transport Safety: 

A CCTV camera system can be used to provide safety to the passengers. For instance, in a subway, operator can check whether every person has boarded before starting the train. 

Monitoring Sports Events:

In the arena, CCTV system is implanted for the fans so that they can see the game even when they are not on seats like in cafes, hallways etc. 

Protecting Students:

Bullying is becoming a major problem for the school children. Many schools around the globe plant CCTV system in the school hallways, canteens, etc. where children are present without the supervision of the teachers. There are some restrictions in using CCTV system in the private places like gym locker areas, bathrooms, and staff room. In school, the head may also use this system to check what is happening in the classroom.

Protecting Staff: 

In banking and especially in the firms where cash is involved, chance of theft comes from staff. Staff members even accused one another for the thievery. Employers can place this camera to protect their staff members. In the public dealings, it can even protect the staff from the customers’ violence and accusations. 

Securing Home:

Not only the big industries and organization, even simple citizens are using CCTV cameras to protect and monitor their houses as well. When connected to the internet, people can even see their house remotely.

How you useCCTV Camera in Singapore is upon you. At the time of their development, nobody knew that it could be used for that many purposes. Who knows, what the future holds. You may have your own ways of using CCTV camera that might not be mentioned here. But, all we know is - necessity is the mother of invention.

5 Reasons for Switching from Analog CCTV camera to IP Camera Surveillance System

The CCTV camera video surveillance system has become very important tool for home and office security. No doubt, the video surveillance system has enhanced the security. However, it can be made more successful with the addition of latest technology. Many companies have enhanced the video and image quality by adding cameras that are more powerful in the surveillance system. The addition of HD cameras in the security system provides more clear image and video of the occurrence. The clear video helps the investigation team to conclude the reports more quickly and virtuously.

In the early security systems, analog CCTV camera was used to capture the image and videos. This security system is still in use at many homes and offices. Although, the capturing result of the analog CCTV camera is low quality. Sometimes, it becomes very difficult to identify the culprits involved in the occurrence. With the passage of time, the latest HD cameras have been invented for office and home security. Moreover, the video recording options have also been modified and enhanced. Currently, IP camera is the most secure and effective surveillance system for home and office security. The homeowners and businessmen are switching their security system from analog CCTV camera to IP camera network. This article includes the top 5 reasons for switching from analog CCTV camera to IP camera surveillance system.

1. Better quality of sound and video:

IP camera system provides better quality of sound and video. The video and sound quality of the analog CCTV camera are usually interfered due to electrical noise and poor connectivity, especially when the distance from camera and DVR is more than one hundred meters. The IP camera is more resistant against electrical noise.

2. Security of recorded evidence:

In many cases, the robbers also take way the DVR device while attempting robbery. So, the victim cannot provide any recorded proof of the evidence. On the other hand, the NVR save the video directly on the network. The IP camera surveillance system is more safe and secure for recording the evidence.

3. Enhanced accessibility and manageability

The IP camera system is easier to manage and access. Now the user can view and video files from anywhere. Even you can access the videos of IP camera network through mobile applications and remote clouds. Simply, you need the internet connection to view and manage the files saved through NVR.

4. Easy power management:

The analog CCTV camera system needs separate power cables to operate cams whereas the IP camera mostly runs through POE (power on Ethernet). IP camera eliminates the issue of connecting separate power cables.

5. Cost effective for remote business management:

Although, the initial cost of NVR is slightly higher than DVR; however, the IP camera system is cheap and easy to modify and enhance. This system is ideal for attaching more cameras. The unique feature of IP camera surveillance system is the remote management of the business. The IP cam security system allows access to store and to manage the data of any work group from different locations. Therefore, the business can be managed remotely from multiple locations.

CCTV Installation in Singapore & How Much It Will Cost

Safety is a concern for almost everyone around the world, from the domestic environment to the corporative settings, which demand effective solutions that ensure the well-being of families and workers as well as the preservation of assets and valuable objects.

This need for safety grows greater every day in Singapore as the number of crimes and robberies rise, so the protection of everyone and everything inside your company or home becomes a priority. On the other hand, most Singapore families have found it necessary to work all day, leaving their children’s care in hands of domestic helpers. Sometimes it is hard for the parents to trust in them and they might want to be sure their kids are in good hands. And not only children, but the elderly also often need to be taken care of by people you do not know so well, so the goal is to make sure your kids and your elder relatives are safe and sound.

What are the main benefits of CCTV installation in Singapore?

As said before, there are certain situations nowadays that make it necessary to count on a reliable system capable of providing a fast response in case of an unwanted event such as robbery, crime, abuse, etc. An effective surveillance system will alert the authorities about the incident so they react in time to prevent further damages in your house or company. And, worst-case scenario, at least it will be easier to determine the responsibilities of those types of events.

But a CCTV installation is not only useful in those cases. Productivity can also be a target of the cameras in the workplace, since they can be used to remotely monitor workers on all departments and verify they are not wasting time during working hours. That way it is possible to make the proper calls to action and get the desired profits from the company.

Another good use of a CCTV system in a company is the safety of workers. In case of an accident, this will allow the emergency department to rapidly address the situation as well as helping the investigation of its causes.

Also, household uses of a CCTV installation in Singapore have been even suggested by local authorities due to the rising number of break-ins that has taken place lately. So crime prevention is a strong reason for installing cameras at home to protect your belongings.

Even for the simplest reasons, such as keeping an eye on your kids while they are alone at home, a CCTV system is a great choice that will allow you to be sure that your beloved ones and valuable objects are safe.

How much does CCTV installation in Singapore cost?

Price ranges are variable. The cost to install CCTV in Singapore will depend on certain factors such as:

  • The number of cameras/channels: Depending on how many areas you want to cover, the number of cameras goes from 1 to 64, or even higher number, which need the right amount of channels to support them.
  • CCTV Camera resolution: This usually goes from 1MP up to 3MP. Evidently, a higher resolution camera will provide a clearer image and the possibility of better zooming if needed (for example, to identify someone or a vehicle’s plate). So the final use of the system is something to take into account when deciding this matter.
  • CCTV Camera Type: There are 3 types of cameras that can be considered. You can choose from analog CCTV Camera, HD analog CCTV camera or IP cameras; although the first is the most affordable option, HD analog CCTV camera and IP cameras offer more possibilities regarding effectiveness since they provide enhanced images. Furthermore, IP cameras are connected to a network and they can activate an alarm if there has been a security breach, transmitting the information to your security provider. Additionally, this type of CCTV installations offer the possibility of remote viewing (and even managing cameras and recording video) from your smartphone or laptop/PC from anywhere in the world by accessing the IP address or via DDNS domain name.
  • CCTV Camera Design: Dome, Hidden and Infrared CCTV cameras are the most popular designs available in the market. Choosing one of them will vary according to the size of the area you need to cover, if cameras must stay undetected or if there are low light conditions.
  • CCTV Video Recorder type: Recording the footage from your CCTV system is often an important need, especially for companies and businesses. Digital Video Recorders (DVR) or Network Video Recorders (NVR) are the main solutions for it, and the difference between them is the type of camera they support - analog CCTV camera for the first, IP camera for the last. So, choosing the Video Recording type for your CCTV camera installation is something you decide along with the camera type, although it is possible to combine both analog and IP cameras and make it work with a hybrid NDVR (Network Digital Video Recording). On the other hand, you should consider factors such as the need of a real time recording (which requires more frames per second, which means how many pictures the system will record in a second) or not, the Hard Drive Storage Capacity -which will determine the recording time (number of days) the system can store before rewriting on the first video- and to consider that the camera resolution and the compression format will affect the recording time. These factors need to be evaluated when making a decision. Finally, you’ll have to choose from an Embedded VR (a device originally designed to work as a Video Recorder) or a PC-based VR (a modified PC with special hardware and software to the same effect). Although Embedded Video Recorders have more stable operative systems, PC-based VRs offer a better way of interaction with the users since they are operated by means of screens and menus.

Typically, the costs may vary from $550 for the most basic arranges to $2,500, for more complex and complete systems and companies often include installation services and warranty in their prices. Keep in mind that the more features a CCTV installation offers, the more expensive it will be, so it is important to establish your real needs so the system is truly adapted to them and the available budget.

What is the most accurate option for a CCTV installation in Singapore?

Most people in Singapore are considering (if they haven’t already installed one) to get a surveillance camera set due to the current break-ins and burglary rates, as well as inventory thefts in warehouses and other types of business. So the first thing to do to choose the right CCTV system is to define the purpose of it, if it will be installed in a house or in a fabric and the coverage in terms of the area that needs to be monitored and if you need indoor/outdoor (or both) cameras; this will give you an idea of how many of them you need as well as their design, type of CCTV camera and resolution.

Second of all, consider the real needs regarding remote viewing capability in order to choose the most appropriate technology and make a precise investment. Also, determine the features you want to have available, such as motion detection, alarms (which not only can alert your security provider but also contact the fire department in case of a fire, for example), amongst other options. By doing this, you can make the right choice about the capacity of the system and build up a complete CCTV installation that covers all your requirements. 

How to choose the best provider of CCTV installation in Singapore?

Finding a good CCTV installation company in Singapore might be difficult since there are many providers of these services. It is recommended to choose from those who are licensed or certifies in order to assure their professionalism and quality. Also, reputation and customers’ opinions must be taken into account because they are a good indicator of how good is the company’s service level. Remember you are going to trust them with your own security, so it is essential for you to choose a provider that gives you enough reliance and confidentiality.

This leads to find out about the Customer Service and Maintenance the company offers, before and after sales. It is desirable to hire a provider who gives advice about the best options for you before installation, offers upgrades as technology changes, provides training for an appropriate use of all devices and, last but not least, has an excellent after-sales service which gives you the benefit of a fast response in case of failure.

Warranty of all the equipment is a must when it comes to a CCTV installation. Most companies offer it for 1 or 2 years for both products and services, but just make sure your choice includes it.

Also, take some time to check the brands of the equipment the company installs. This can be a fair way to know what kind of technology they are able to work with and, at the same time, you can be sure it suits your requirements.

In conclusion, a CCTV installation in Singapore is a necessity that has been increasing in recent years, whether at home or in your business, so it is useful to evaluate the different options offered in the market. The protection of your family and properties is something to be carefully considered and it should be trusted to a reliable provider who can fulfill your requirements so that safety is well-covered instead of being an issue.

How CCTV Works

Closed circuit TV camera, typically abbreviated as CCTV camera, comprises at least one camera transmitting data to a monitor or video recorder. The data transmitted can either be video and audio, or video only. A CCTV camera must never be mistaken for an ordinary TV. An ordinary television receives publicly broadcasted contents while a CCTV doesn’t. In everyday use, CCTV cameras are fitted on buildings, gates, and other structures purely for surveillance purposes. The closed circuit system can either be used to monitor live proceedings like in a supermarket or documented for later reference.

CCTV camera components and their working

The complete closed circuit TV system (CCTV system) consists of:

  • Security Cameras (Analog or Digital Camera)
  • Cables (RJ45 or RJ59 Cables)
  • Video recorders (DVR or NVR)
  • Storage unit - typically Hard disk 
  • A display unit (Optional, such as a Monitor)

Security Camera

Security camera captures the video of the source. An opened aperture at the front of the camera captures light stream through the camera lens. The light stream is captured by a digital chip that is fitted inside the camera and is converted into the continuous stream of images. The camera records the signal to be transmitted either through cables or wirelessly. The distance between the camera and the object is determined by the camera lens specifications. 

Infrared Light Emitting Diodes (IR LEDs) are used as sensing devices in CCTV cameras. The light sensor is used to detect the ambient light level i.e. it detects the brightness of light it receives and transforms it into a numeric value that tells the percentage of brightness.

Due to the digital technology employed in data recording and processing, it is possible to receive sharp images, clear audio and fewer signal interferences from the wireless cameras. This type of camera is often referred as “IP Camera” (we will talk in more details later)

Cables

The cables are just the wires that are used to connect different equipments like CCTV camera, monitor, recorders, modem etc. in a CCTV camera setup. For CCTV cameras, the cables used are either RJ45 or RJ59 cables. These cables,  if RJ59, may include BNC connectors to connect camera to video output (such as Monitor), power connectors etc. As for a RJ45 cable, cat 5e or cat 6 cables are most frequently used in CCTV camera setup.

Video recorders

When a CCTV camera sends video signals that might be useful at a later date it must be documented somewhere. There are two main types of recorders namely digital and analog recorders. Nowadays, Digital Video Recorders (DVRs) or Network Video Recorders (NVRs) are used to record CCTV camera footage. 

Digital Video Recorders (DVR)

Digital Video Recorder, or DVR, stores the transmitted video images in either stand-alone devices or an external storage backup system. The basic working principles of analog recorders and DVRs are closely related except that digital video recorders document the data in digital format. The video data is coded, stored and processed at DVR only. DVR can be easily accessed through a web browser, or CCTV centralised software, or a mobile application.

The number of images recorded on a digital video recorder depends on the following factors:

  • The desired number of frames to be recorded in every second
  • The total number of CCTV cameras linked to the DVRs
  • The video image compression technique used.
  • The DVRs image resolution, bitrate, etc

Network Video Recorder (NVR)

The NVR work same as DVR, only the difference is the inputs. Unlike DVR, the NVR takes its input from a network rather than the direct connection to a video capture device. NVR always works with IP camera. The video on the NVR is coded and processed at the IP camera and is stored on it for remote viewing. Furthermore, some additional functions like compression or tagging with Meta data can be done on NVR. The surveillance systems with NVR can be either wire, or wireless (By the way, wireless NVR works well theoretically, but in reality, wireless NVR is not the main stream because of the stability issue with the wireless signal), and can also be easily accessed through a web browser, or CCTV centralised software, or a mobile application.

Hard Disk

The Hard disk is a storage device which stores the video captured by the security camera so that it can be used later. These CCTV hard disks are fitted within the video recorders. To view the video recordings on the hard disk, you can directly connect the DVR or NVR to monitor. 

Note that you should always choose those “surveillance grade” hard disks, which are designed to run 24x7 and made more durable compared with normal computer hard disks.

A display unit (Monitor)

The display unit, or a monitor, takes the video image from DVR, or NVR and outputs it on the screen. You can see the video or image on screen that is been captured by the camera. The monitor can be a monochrome screen or a colored screen. Nowadays, High Definition (HD) colored LED monitors are quite commonly used to watch the videos.

Different Categories of CCTV cameras

There are many ways to categorised CCTV cameras. We will use the following subheadings to classify CCTV cameras systems: 

Wired and wireless CCTVs

All CCTV systems have to record and transmit the documented picture. Based on transmission mode there exist two categories of CCTV cameras; 

  • Wired cameras, those that transmit their video signals via a cable
  • Wireless cameras that require no signal transmission cable

Wired CCTV systems typically use a communication cable similar to the one feeding antennas (RF cable). One major drawback in using wired CCTV cameras is that as the transmission range increases more than 300 meters, the signal may become weaker. To manage the problem, one should consider using appropriate networking cables (for example  Cat6), as well as adding switches on the halfway, or use high-quality signal boosters. 

In a multichannel closed circuit TV system, several cameras are strategically placed at various locations and can be designed to be interconnected through a multi-viewer circuit to allow close monitoring from a single computer or screen. 

For a small house, to have non-messy interconnection, a multichannel system can use wireless CCTV cameras. Such cameras would negate transmission cables as only power lines would be a must, hence leaving behind a neat finishing. The wireless CCTV camera communication can cover 20 meters or even more. This might make such cameras ideal for complex structures.

But, the big drawbacks are the strength of the wireless signal, which is determined by the infrastructure of how you design your wireless network. Scientific research has already shown that wireless signal can drop by up to 90% if it goes through a concrete wall with steel inside. This can become a big issue when connecting the wireless CCTV cameras - unstable connection, hence loss of video records, is simply can’t be accepted for surveillance CCTV cameras.

Analog CCTV camera ( uses DVR) or Internet Protocol (IP Camera) (uses NVR) CCTV

Leaving technologies behind, to normal users, the primary difference between analog and more digitalized IP camera is the video image quality, in term of sharpness and video image resolution. The IP cameras come under wired or wireless category of CCTV camera. IP cameras use NVR and can provide a much higher image resolution (megapixels) than the conventional analog TVL CCTV cameras. IP cameras are therefore preferred conventional analog TVL cameras due to the following reasons:

  • They require less amount of cables to be installed: a POE IP cameras require only one networking cable connecting it to the video recorder.
  • Provides much sharper images than analog cameras
  • IP digital signals are not so prone to signal interference
  • IP cameras are easily accessible through a Web browser.

However, one major drawback in using IP surveillance cameras is that they are costly. A better option might be considering to use analog HD CCTV, in this article, we use HikVision HD-TVI CCTV camera as illustration. Although analog in nature, HikVision HD-TVI surveillance CCTV cameras can give high definition video images and possess night vision capability. 

One point worth noting about HD-TVI CCTV cameras is that they are compatible with the older analog non-HD types. Hence, one can easily upgrade to the HD-TVI CCTV cameras.

How an IP camera operates

Internet protocol cameras (IP Cameras) provide surveillance function but through a digital network. These cameras rely on the computer network-both in sending and receiving information. The connection can either be through the wires (cat5e or Cat6) or Wi-Fi.

  • Since the data exchange is through the internet, the operator doesn’t need to be in a fixed location all the time.
  • When you connect an IP camera to network, and you can monitor your premises from any location.
  • You just have to open the web browser on Computer, enter the Static IP address / or DDNS domain name of the camera, to watch the live feed; or you can just open smart phone application to do so. 
  • Though the IP cameras are tiny, they have high resolution and even give a high definition.
  • These new-age IP cameras can be remotely accessed, controlled, and repositioned as desired. You don’t have to be physically near the camera to rotate it to a given angle.

Furthermore, some modern IP cameras are quite responsive to heat movement or sound. Therefore having been fixed in a room, the camera will only go live on the recording when there is an activity to be recorded. The IP camera won’t need to be adjusted to the direction of the incident; due to its sensitiveness to sound, it will automatically detect the origin of the sound and rotate, tilt and record the event.

Wide Dynamic Range (WDR) is also an important function for IP cameras. This function helps to digitally enhance the image quality in some certain scenes, to cope up with difficult lighting conditions. They can differentiate objects even in low light situations. 

Typical uses of CCTV cameras

Crime detection or prevention

The chief use of CCTV cameras is for surveying an area with the aim of detecting and preventing crime. Most car parks, supermarkets, major stores and other public places fit surveillance cameras for this reason.

Industrial use

Monitoring of critical industrial processes mainly employs CCTV cameras and not human beings. This is very true in the case of chemical based or nuclear-based industries. For example, thermo-graphic CCTV cameras find unique application in nuclear fuel plant. 

Traffic use

The main cities do experience huge traffic congestion or accidents. Closed circuit cameras can then be fitted along the streets so as to automatically record any accident or indicate the roads with more traffic jam.

Used in schools

In many developed countries, CCTV camera system is used to keep a check on students who are prone to vandalizing school properties or those who find pleasure in bullying their colleagues.

Transport industry

 Surveillance cameras are also used in the transportation services. For example in an underground train, through the utilization of a surveillance camera, an operator can trace the passengers’ movements so as to know when to open or close the doors.

Monitoring employees

Major organizations and companies use CCTV cameras to keep track of employees in different sections. The cameras would send video signals for each process. Through that, it is possible to pinpoint for a delayed stage of production.

CCTV cameras are sometimes prone to vandalism hence rendering them ineffective. To overcome this problem, manufacturers, have come up with cameras which are resistive to different things like:

  • An explosion proof casing
  • Dust resistive housings
  • Bullet resistive casings

Hikvision vs. Dahua: Comparison of IP Camera DS-2CD2142FWD-IWS and IPC-HDBW4431E-AS

Source of the article: https://cctvcamera.com.sg/hikvision-dahua-comparison-ip-camera-2cd2142fwd-hdbw4431e/

Any DIY enthusiast will happily tell you that Hikvision and Dahua CCTV and IP cameras are the absolute best choice for the task. Both of these security camera brands are extremely popular in Singapore, with Hikvision probably being a more sought-after choice as of now. There is no particular reason for that phenomenon, although generally speaking, Hikvision is the slightly cheaper choice out of the two options.

In any case, Hikvision is the world-leading IP camera manufacturer as of right now, and at the time of writing this (2017), it has a 17% market share. Dahua is the second one with a respectable market share of 5.5%. (Data source: IHS)

For demonstration purposes, we will be comparing the latest 4MP IP cameras, Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS, because this resolution will likely become the golden standard for home CCTV cameras in the near future.

1. ONVIF and RTSP support for Hikvision and Dahua IP Cameras

Dahua-DH-IPC-HDBW4431E-AS

Dahua-DH-IPC-HDBW4431E-AS IP Camera

ONVIF and RTSP are probably among some features you should look for in an IP camera, especially if you have existing NVR. Hikvision as well as Dahua security IP cameras both support them just fine.

ONVIF is there to make sure the camera is compatible with equipment from third-party manufacturers, while RTSP allows software and other equipment to access your camera’s video stream. One example is the ever-popular VLC player.

2. The sensor used in the IP Cameras

Both Hikvision and Dahua IP cameras have a 1/3” Progressive Scan CMOS sensor, the most common one you can find in these type of IP cameras.

When buying a security camera, the size of the sensor is quite important. It directly influences the low light ability of a camera, and this holds true for camcorders as well. Basically, larger sensors are better suited to operate in low light conditions.

Here is how it works: by trying to cram more and more pixels into a sensor that has the same size, additional noise is created, which – in turn – reduces the details in the video. As you can see, a larger sensor effectively reduces the problem.

In any case, both Hikvision, as well as Dahua 4MP models, have true 120dB Wide Dynamic Range (WDR). This serves to further improve the video quality.

3. Minimum illumination

Minimum illumination measures the minimum amount of light required for a CCTV camera to produce a viewable image. In this category, both IP cameras are the same: both are capable of 0.01 lux and 0 lux with IR on.

4. Lenses used in Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS

cctv_camera_ip_camera_home

Hikvision DS-2CD2142FWD IP Camera

Both Hikvision and Dahua security cameras allow multiple fixed lenses with different focal lengths. Hikvision has 2.8mm, 4mm and 6mm, 8mm and 12mm lenses, while Dahua uses 2.8mm, 3.6mm, and 6mm. Hikvision offers a consumer a bit more options.

5. Max bitrate of the IP Cameras

(Read here to know what is bitrate) Another difference between Hikvision vs Dahua security cameras is that Hikvision’s model has a max bitrate of 16Mbps, while the Dahua’s model has a max bitrate of 10 Mbps. However, that is a bit far from being a reason for concern. Both bitrates of up to 10 Mbps are usually more than enough for what you’re going to need.

6. Weight and dimensions

In terms of weight, both cameras are nearly identical: they are both around 0.5 kg. As for the dimension, Hikvision is 4.4” × 3.2”, while Dahua is 4.33”×3.19”. Again, these differences are minimal and noticeable only if you put one camera next to another to compare them. In practical scenarios, the difference is probably not going to matter.

7. Price of the IP Cameras

Generally, Hikvision security IP cameras tend to be slightly cheaper for some reason. However, there are different ranges of IP cameras with different features coming with totally different price ranges.

Therefore, we recommend that you make your decision based on the features each of these models provide,  not price alone.

8. Resolution of the IP Cameras

Both Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS IP cameras have the resolution of 2688 x 1520 as the maximum.

9. Simultaneous video streams

Here is another difference between the brands: in this category, Dahua outperforms Hikvision, since Dahua allows for 3 simultaneous video streams at different resolutions, while Hikvision only allows for 2 streams.

Note: this is only relevant if you’re trying to do multiple simultaneous streams at different resolutions. If the resolutions are going to be of the same quality, this will not affect you in any way.

10. Frame rates

Typically, you can expect the frame rate to jump anywhere between 20 and 30 fps. Dahua’s technical sheet promises for it to never fall below 25 fps, while Hikvision runs at 20fps with the resolution of 2688×1520, 25fps with the resolutions of 1920×1080 and 1280×720. In all of the other modes, however, the minimal fps you can expect to see is 25.

11. Motion detection

Motion detection is one of the most desirable features for a reason: it helps conserve storage space, as well as saves time when reviewing the recorded footage (since you probably only want to go over the parts when something moves unexpectedly). Long story short: both models support motion detection feature.

Hikvision Protects Singapore's World-class Building

This is a press release published by Hikvision. The original article was at http://www.hikvision.com/en/SuccessStoryDetail_32_i1130.html (URL has been removed since Oct 2017). The client's name has been made anonymous since Oct 2017

Hikvision Protects Singapore's World-class Building

(15 April 2016) The stunning and iconic building – is a more than 20,000 square meter architecture masterpiece located in the center of Singapore. One of the busiest center in the world since its opening in 2002, the building has hosted more than 31,000 events, drawing a total of 84 million visitors as of 2016.

With its distinctive twin shells, this architectural masterpiece features world-class spaces in its two main venues – the Hall A and the Hall B; with capacities of 1,800 and 2,000 respectively. In March 2014, the Building was listed as one of the world’s 15 most beautiful building by Hamburg-based building-data company Emporis.

Today, the Building is renowned for possessing some of the best events in the world. With its innovative and refined characteristics, the world-class building suits a wide range of events. The hall regularly features world-renowned companies and guests, contributing to Singapore’s international and cultural vibrancy.

In 2014, after a decade of operation, management at the Buidling, a not-for-profit organization and registered charity – decided to update their existing CCTV surveillance system. Working with Hikvision, a new surveillance system was designed to deliver effective internal and external surveillance and perimeter protection for this prestigious arts center.

The challenge faced by HikVision

The Building’s prominent faade directly faces a number of tourists spots in Singapore. In order to preserve the aesthetics of the iconic arts building, the new IP-over-fiber surveillance system utilized carefully planned out locations for every CCTV camera.

Beyond providing effective video for general security, the new system also needed to provide 95% visual coverage of the entire site to assist with day-to-day management and visitor traffic flow as well as the implementation of required health & safety practices.

The Solution faced by HikVision

In the main hallway and inside the building, Hikvision’s 2 MP Full HD Indoor Dome Network Cameras (model number DS-2CD4124F-IZ) were installed to provide 1080P imaging; these cameras features Smart Focus motorized VF lenses, BLC, Smart audio, and intruder-detection functionality. Providing 24/7 coverage in the car park, 2 MP Full HD Outdoor Dome Network Cameras (DS-2CD4324F-IZ) were installed. Featuring built-in infrared (IR) LEDs, they can provide up to 165 feet (30m) of night-time viewing in complete darkness.

Preserving the internal aesthetics of the building’s architecture, compact and unobtrusive IR Mini Dome Network Cameras (DS-2CD2532F-IWS) were installed in the reception and counter areas. To assist with any disputes, the Hikvision Mini Domes, with their built-in microphones, were installed at the ticket counters and monitor all ticketing transactions while also observing any problems that might occur at the entry turnstiles. The surveillance footage from these dome cameras is a great asset in helping the building’s management team speed-up the flow of guest traffic by reducing queues and waiting times.

Providing an ideal surveillance solution to monitor the building’s perimeter, surrounding driveways, and walkways, Hikvision’s IP66-rated, 2 MP Network PTZ Dome Cameras (DS-2DF5286-A3) were installed, fully utilizing their 30x optical and 16x digital zoom and Smart Tracking functionality.

Powerful control faced by HikVision

In the control room, supporting live viewing, storage, playback, and control of the over 300 network IP cameras, are Hikvision’s DS-9664NI-XT-Series NVRs using one of the possible RAID configurations. In order to support the large number of PTZ speed domes, general security, and event management, the NVRs record both audio and video from each camera. Ideal for any size installation, the NVRs support hot-swappable HDDs and RAID 0, 1, 5, and 10 storage.

To control Hikvision’s full range of Smart camera functions, including Smart search and playback, Smart detection, and record backup, as well as Smart applications such as people counting, heat mapping, and interactive mapping, all system equipment is managed by Hikvision’s open-platform iVMS-5200E Enterprise Video Management Software. Designed specifically for large-scale projects with multiple channel surveillance, this VMS offers video preview, video playback, and comprehensive alarm management. Fully integrated to the Hikvision array of NVRs, the iVMS-5200E also provides full control over the customization of video tags, playback by tag, and video searching; and for additional security of video footage, the locking and unlocking of any recorded files.

“We proposed the Hikvision solution based on our experience of using the company’s products on many other successful projects. We know Hikvision products are reliable and serve the needs of the customer perfectly. The end-user was delighted to work with us and Hikvision, the number one brand in video surveillance.”

With the Hikvision-powered security system now up and running, the Building’s team of dedicated professionals have a powerful security and site management surveillance tool at their fingertips, assisting their quest to offer a great experience for visitors, inspiring audiences, and cultivating the culture of Singapore.

Network of CCTV cameras proving effective

Singapore, Mar 9, 2016

This is the article from Straits Times on Mar 9, 2016. All rights reserved by SPH. Original Source: http://www.straitstimes.com/singapore/network-of-cctv-cameras-proving-effective

"They are scaring loan sharks and litterbugs, ensuring smooth traffic and boosting safety."

Thousands of closed-circuit television (CCTV) cameras islandwide have helped deter loan sharks, nab litterbugs and stop illegal parking, according to government figures.

And residents generally welcome the reassurance that such surveillance provides, said Members of Parliament.

"I quite often receive requests to put cameras up. I haven't received any to take cameras down," said Holland-Bukit Timah GRC MP Liang Eng Hwa. Most of the Housing Board blocks in his area now have CCTV cameras.

This is due to the police's nationwide push to have cameras in every HDB block by the end of this year.

Since 2012, over 52,000 police cameras have been installed in 8,600 blocks, Dr Teo Ho Pin said in Parliament in January. He is coordinating chairman for the town councils run by the People's Action Party.

Ang Mo Kio GRC MP Gan Thiam Poh said: "I do notice that there are improvements, especially in the cases of loan-shark harassment that used to be quite common."

Potong Pasir MP Sitoh Yih Pin used to get loan-shark harassment cases at his Meet-the-People Sessions every month, before cameras were installed.

"Now I haven't got any for quite a while," he said.

Police figures released last month showed that blocks with cameras see fewer unlicensed moneylender harassment cases involving property damage. The number of such cases reported at 2,152 blocks with police cameras plummeted from 1,617 in 2013 - before those blocks had cameras - to just 426 last year.

Toa Payoh resident Tan Li Choo has noticed more CCTV cameras appearing, but does not consider them an invasion of privacy. "It's okay if they are for safety purposes only," said the unemployed 38-year-old.

Footage from police cameras has led to the arrests of unlicensed moneylenders in 360 cases of harassment since 2012, according to the police Annual Crime Brief 2015 released last month.

Town councils also install CCTVs of their own inside lifts. "It does help against anti-social behaviour such as littering, urination and vandalism," said an East Coast-Fengshan Town Council spokesman.

The National Environment Agency (NEA) has its own eyes too, with almost 3,000 cameras in HDB estates to catch high-rise litterbugs, Senior Minister of State for the Environment and Water Resources Amy Khor said in Parliament earlier this month. Litterbugs are successfully identified in about a third of cases caught on camera, she added.

In January last year, for instance, NEA's cameras helped nab a 38-year-old Sengkang resident who threw 34 cigarette butts out of his flat window over four days. He was fined a record $19,800.

Meanwhile, more than 300 parking enforcement cameras have been put up by the Land Transport Authority (LTA), helping to cut cases of illegal parking by as much as 90 per cent, the LTA told The Straits Times last September.

Traffic Police speed cameras also discourage reckless driving, said Mr Sitoh, who heads the Government Parliamentary Committee for Transport. "By and large, Singapore drivers are very responsible. But I think having the cameras there does help, it's a good reminder to our motorists to drive carefully," he said.

However, Associate Professor Lee Der-Horng, a transport researcher at the National University of Singapore, noted that drivers might slow down when they see a speed camera but speed up again afterwards. This is unavoidable unless actual mindsets can be changed, he said. "Before that overall awareness is there, the existence of cameras is still very much necessary."

NUS sociologist Daniel Goh noted that anti-social behaviour is usually opportunistic.

"Thus camera surveillance, if effective, tends to displace the behaviour to other locations rather than change the behaviour."

Still, cameras can be useful as one tool among others, he added. They can help create the habit of proper behaviour - which can then be reinforced with education about "communal norms of right and wrong".

"Fear of being caught by camera surveillance inculcates a habit, and if the person is educated with the norms, the camera will then subsequently remind him of the norms," he concluded.
