The evolution of IP video has placed a lot of attention on the resolution of the video, as measured in the growing number of pixels in a frame. But another variable, receiving less attention, is the number of frames captured per minute (fps). We inherited the idea of “full-frame-rate” video from the analog world, but increasing numbers of pixels (and more data!) have sometimes led to the use of slower frame rates. We asked our Expert Panel: What is the value of the “full-frame-rate” video? Absent specific compliance requirements, what might suffice as an acceptable frame rate (i.e., less than 30 frames per second [NTSC] or 25 frames per second [PAL])?

As with any variable related to video surveillance of the security system, the question of frame rate comes down to determining the needs of the application. As higher pixel counts (and limited storage and bandwidth resources) put downward pressure on frame rates, it’s important that integrators and end-users manage the compromises well. After all, what good is a really clear image if it misses action that happened between frames?
