Tell me about frames per second

One thing you need to be careful about when analyzing specifications of a DVR with respect to “frames”, “fields” or “images” per second capabilities is do they have the right specifications.

Here is a brief understanding about frames per second how it is applied to CCTV.
The total number of frames/images per second for the entire CCTV System to be used across all cameras being the whole total
The number of frames each camera will use when recording
Take in to account the display speed and the Recording Speed

The frame rate issue is a complex issue. The fact is the rates that manufacturers quote are usually the maximum rate and that there are other factors involved which will determine the correct frame rates that will be needed.

when manufacturers quote IPS being Images per second and others quote FRPS being frames per second you would think it means the same well that is not correct.1 IPS actually = 2 FPS as the standard is 30 frames per second as this is the highest the human eye can see.

This is where it becomes more relevant and important to use quality CCTV equipment because the recording device will be displaying and capturing at the same time therefor the performance may deteriorate, as they may be using the same components to accomplish different tasks. One function must wait for the other or both perform at a reduced rate. To counteract this problem some companies use a separate video display card (decoder), which generates real-time video on all channels all the time but you can imagine the cheaper manufacturers to save some and more will not worry about doing this separation.

So how does it all work well there are 2 types of physical compression; hardware and software. It is actually a case of compression and decompression. Compress it to travel down the network and decompress to transmit when it comes out the other side, so the name “Codec.” When you use hardware compression there is no loss of efficiency, as all the work is being done on the board by the hardware components. That is of course if you have all the right components.
