What is the difference between my home VCR and a VCR used with CCTV?
The difference between most home VCRs and VCRs designed for use with CCTV is the speed of recording. Generally, home VCRs will record up to 8 hours of video on a single tape. A VCR designed specifically for use with CCTV in time-lapse mode, can record between 12 and 960 hours of video, on one T-120 tape.
