Face Recognition Technology and Its Use in Door Access System

Office Door Access control systems are upgrading with the current updates being sophisticated face control technology. We have moved from admiring this technology in Sci-Fi to having it in our offices. Face recognition technology in access control systems makes it possible for users to capture 3D live images of individuals accessing their premises and comparing these images with their database to identify the said individual.

As complicated as this process sounds, it is quite easy and fast. Face recognition access control systems use end points or nodal points on an individual’s face to measure variables like the length or the width of the nose, the depth of the eye sockets or the shapes of one’s cheekbones. All this facial information is referred to as a faceprint, and it is used to compare against any data captured when one is accessing the building.

With Hikvision’s access control system, you will have complete control over who comes in or goes out. Every day, we are all looking for systems that not only provide us with end-to-end security solutions but one that is advanced enough for excellent face recognition even in zero lighting situations.

Server Racks and Their Sizes

As we know, server racks come in various types and dimensions, depending on the specific needs and the sizing of the equipment that will be mounted on it. In a particular way, the height of the rack needs to be considered, since it indicates the amount of spaces that can be occupied by the equipment.

Server racks have their own measuring unit, which is associated with the height of the device that will be installed. While the width can only have two sizes (19 or 23 inches, the first one being the standard and most common), the height increases by a rate of 1.75 inches, and this quantity is called rack unit or just “U”. That said, it is possible to understand the notation used for server rack sizing: 1U, 2U, 3U and so on.

For example, a 9U rack has a width of 19 inches (for a standard rack) and a height of 15.75 inches (1.75 multiplied by 9). The size of the rack will depend on several factors, starting with the size and type of business activity of the company, which will determine the real needs regarding the number of devices for networking, communications, or any other applications.

Evidently, the needs of a small retail shop will be different from those of a telecommunications company or a small office.

Categorization of Server Racks

Server racks can be classified according to many features but the most usual is to categorize them by size. We have grouped them in three general categories, considering the area of application.

1U to 12U Server Racks

These rack sizes have a common usage on IT applications. They can vary depending on each specific case, where space, traffic and other conditions must be taken into account.

Smaller racks, usually ranging from 1U up to 6U are used for low height installations that count with some kind of anchoring for wall mounting or for that equipment that can be placed on the ground. These are often found in telecommunication applications as well as monitoring equipment.

It is important to consider their weight capacity due to the fact that some devices (such as UPS’s, among others) might need a strong structure in order to be securely held.

18U, 22U and 32U server racks

These are the most common among the medium size racks. Telecommunication devices, servers and network equipment can be stored in these structures, allowing visibility, good ventilation and many possibilities of arrangement.

This is a good option for small equipment, which provides security as well as a higher capacity in terms of weight.
Among the advantages of this group of server racks, we can mention the following:

Easy and fast assembly
Great mobility (most of them are provided with wheels so that it is possible to move them from one place to other)
Versatility when mounting and arranging the equipment thanks to the adjustable mounting option, with removable doors
Security and safe functioning, with a structure that allows ventilation for the system

“Higher-U” Server racks: 42U, 45U and 48U

Most racks are 42U, (about two meters high) which are used for professional audio and video equipment, and of course, for housing the biggest servers and IT networks. This size allows an efficient arrangement of all the components as well as an important saving of space, a very significant feature when it comes to such an amount of devices.

Industrial energy and automation hardware are also two of the main uses of large-size racks; the range of 45U-48U is the most common in this type of companies.
These racks are floor-standing structures and sometimes they can be customized in order to reach up to 58U for special cases in which there are a huge number of devices, for example, high-density data centers.

In addition, this category of server racks allows the possibility for a future expansion of the equipment, a great benefit for fast-growing businesses. They are also suitable if extra space is needed for cabling and other connections.

Compatibility with additional accessories is also an important feature. These racks are designed in a way that facilitates the maintenance of the equipment, an efficient airflow and allow a simple and fast installation.

Summary of the Sizes of Popular Server Racks

We have summarized the sizes of the most popular server racks in Singapore in the table below, so you can easily refer to it to find the most suitable server rack for your office or home:

How Many U?	Height (cm)	Width (cm)	Depth (cm)

Buy Server Rack in Singapore: What You Need to Know

Considering to buy a server rack for your office or your home? Find out all the information required before buying the server rack: type of server racks, uses of server racks, features of server racks.

Useful Article: Server Racks and Their Sizes

The NVR or DVR of CCTV Cameras, and some electronic equipment modules such as data processing centers, professional audio/video equipment, those used in telecommunications, and a wide variety of applications, require a lot of space due to the amount of parts and pieces that they comprise.

Server racks offer an excellent solution when it comes to find an optimal distribution, space saving and efficiency.

What is a Server Rack?

A server rack is a structure consisting of vertical columns and horizontal shelves that form a frame. This framework as special support for different kinds of computerized systems with special requirements.

More specifically, the most commonly used 19-inch server racks are standardized structures that provide an organized array of all the parts needed for the functioning of the equipment. A 19-inch rack owes its name to the measure of the rack’s width, which is defined so that the modules can fit perfectly, making it easier to mount and arrange them. All dimensions of a 19-inch server rack are normalized so that they are compatible with any equipment, regardless of the maker.

Types of Server Racks

There are several types of server racks, depending on the presence or absence of doors, rails, front and back doors, and side panels, among other features.

Open frame racks have two or four rails for installing equipment. They have no doors or side structure. They are also known as four-post racks and their use is very popular for data centers, thanks to their configuration which allows a better arrangement of cabling and power sources.

A two-post rack only has two vertical columns made of metal, usually aluminum, which can be attached to the floor or to the roof. This kind of rack is mostly used in places where earthquake protection is needed.

Server cabinets, on the other side, include keys, rails, doors and protective panels on the side. Sometimes these protective panels are isolated with foam layers for specific uses.

Also, there are racks with wheels, for those cases where mobility is needed. Some racks that can be mounted in walls, a good solution for locations with limited space.

Main Features of Server Racks

Server racks are provided with edges on each one of the sides so that it is possible to fasten the module with the use of screws for a safe installation. This is very important because the equipment installed on racks is often expensive and its safety must be handled with care.

As a standardized structure, the height of a server rack is measured in units identified with the letter “U” which is equivalent to 1.75 inches (44.45 mm). Accordingly, there are frames that range from 4U up to 42U, depending on the required size. This represents an advantage regarding adaptability since requirements can be very different from one case to another.

The depth of a server rack is also an important measure. Though it is not a standardized measure, it usually ranges from 600 to 1200 mm for the deepest hardware pieces. It is necessary to have in mind that this number needs to be greater than the equipment’s depth in order to leave enough space for cabling and connections. In addition, when calculating the space and choosing the right server rack, it is important to include the necessary space between the hardware and the cabinet walls, if any, for good ventilation. This is necessary for the good functioning of the equipment, which can overheat easily.

Uses of Server Racks

Server racks are mostly known for their use in data processing centers, more specifically for housing servers, commuters, routers, NVR/DVR of CCTV Cameras, switches, and other network devices.

These frames are mainly used in companies that need centralized cabling and places with space limitations. Their structure is able to support monitors, keyboards and many types of systems and devices of different sizes and shapes. This modular solution is the most appropriate for easy addition or substitution of components. The rack allows an easy process of expansion, change of accessories, repairs or any other kind of intervention, even without the need of shutting down the system in order to do that.

This means a huge benefit in terms of productivity, since there would be no downtime whenever a change is needed, which represents a great saving for the company.
Server racks are the perfect solution for companies and enterprises that need a continuous workflow.

Bit Rate Explanation of CCTV Security Camera and IP Camera

Keywords: CCTV, Security Camera, IP Camera, DVR, NVR, Bit Rate, Constant Bit Rate, Variable Bit Rate

First of all, let's start with the word, bit. A bit is an acronym for "binary digit," the smallest possible unit of information in digital computing and networking. 8 bits make one byte. 1024 bytes make 1MB. 1024MB make 1GB, 1024GB make 1TB. You should probably be familiar with the TB now, because all our CCTV, and IP camera solutions are based on multiple TB harddisk capacity.

Coming back to bit rate, bit rate is the number of bits that pass a given point in a telecommunication network in a given amount of time, usually a second. A bit rate is usually measured in some multiple of bits per second - for example, kilobits, or thousands of bits per second (Kbps). So when we talk about the bit rate for a CCTV camera, or IP Camera, it can refer to the number of bits transferred per second for the combination of video and audio streams, again, usually in Kbps.

Constant bit rate (CBR) and variable bit rate (VBR) are the main types of bit rate encoding.

Constant Bit Rate

With constant bit rate, a fixed bit rate and bandwidth is used throughout the entire track or encoded video file. This is favoured when only limited bandwidth is available, because bit rate that can be predefined. In addition, with CBR, the file size is more predictable. However, the disadvantage with CBR is that when there is, for instance, increased activity in front of the CCTV camera that results in a bit rate that is higher than the target rate, the restriction to keep the bit rate constant results in a poorer image quality and lower frame rate.

Variable Bit Rate

With variable bit rate, a changeable bit rate (hence the bandwidth) is used throughout the encoded CCTV or IP Camera video file. The variability of bit rates allows for video to be recorded at a lower bit rate when the video scene on screen is less complex, and at a higher bit rate when the video scene is more complex. This eventually means that bandwidth use will increase when there is a lot of activity in a scene and will decrease when there is no motion. This is often desirable in CCTV surveillance applications where there is a need for high quality, particularly if there is motion in a scene. In short, image quality is better with variable bit rates than with constant bit rates. However, the disadvantage is that pre-planning the CCTV and IP camera video storage requirements becomes more challenging as the bit rate changes with the complexity of scenes.

All our CCTV products, including NVRs, DVRs, Analog CCTV camera, and IP cameras will allow you to choose either constant or variable bit rates when recording video.

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.
