Time lapse vcr, английский
- (tl vcr). a video recorder, most often in vhs format, that can prolong the video recording on a single tape up to 960 hours (this refers to a 180 min tape). this type of vcrs are very often used in cctv systems. the principle of operation is very simple -
- A type of industrial video recorder that can be set to record continuously over long periods. typically, this can be from three hours to 480 hours, achieved by the tape mechanism moving in steps and recording one frame at a time. this means that if set to record over long periods much information can be lost. for instance, in the 72-hour mode, only 3 frames/second will be recorded instead of 25 frames/second in the real time mode. on receipt of an alarm signal these machines can be automatically switched to real time mode. with rapid advances in digital storage and retrieval techniques the mechanical video recorder is now nearing the end of its life in industrial security systems.
