Why don I need 30 frames per second video recording on all security cameras?
Video security systems are generally intended to allow the image capturing of intruders and crime perpetrators. The purpose of these systems is not to make movie quality videos. Recording rates of as low as 1 or 2 frames per second will catch virtually any criminal act. Even at these frame rates, with many cameras all recording on motion, the compressed video files produced are multi-Gigabytes per day. Imagine what the file sizes would be if security cameras were all recording at 30 frames per second! Of course, recording frame rates must be fast enough so as not to miss anything – a major problem with multi-camera time-lapse VCR systems. Sometimes time lapsing on VCR systems can be as great as 1 frame very 5 or 6 seconds, in order to get the number of hours of recording time high enough. This kind of recording frame rate can certainly miss many things, but a digital system recording at anywhere from 1 to 6 frames per second should miss nothing and still provide many days of recording
