With a proper IP Camera surveillance system, it is important to consider the storage requirements when implementing the CCTV security camera solution. There are a number of factors you should consider: the number of IP cameras, the image resolution used, bit rates, frame rates, the compression type and ratio, and scene complexity, etc. Among these factors, the factors to decide the IP Camera storage will be bit rates, and number of IP cameras you are going to install.
SafeTrolley has come out with the below tool which will help you to have a rough idea of the hard-disk space you will require when the recording time is given, or the number of days record which the NVR can keep, when the hard-disk space is given.
Please note that for the sake of calculation, the bit rate has to be a constant variable; in reality, for our IP Camera solution, we can set the bit rate to be a variable, which means, in simple words, our IP camera and NVR will intelligently lower the bit rate whenever necessary, which results in a lower disk space consumption - you will probably be able to keep the record for a longer time than you see below!
