Video security systems are intended to capture images of 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 several gigabytes daily. Consider the file sizes if CCTV cameras were all recording at 30 frames per second. Recording frame rates must be fast enough so as not to miss anything.

Digital system recording at anywhere from 1 to 6 frames per second should miss nothing and still provide many days of recording capacity. There are some applications, however, that do require faster recording rates (e.g. sleight of hand activities at cash registers or casinos) and we provide the high speed 120fps, 240fps and 480fps video capture boards and DVRs available for these purposes.
