A Time-Lapse VCR records fewer frames per second to extend tape use. Common before digital recording.
A type of video recorder that can be set to record continuously over long periods. This can be anything from two hours to 960 hours, achieved by the tape moving in steps and recording one image at a time. This means that if set to record over long periods much information is lost and only occasional images are recorded. On receipt of an alarm signal these machines can be automatically switched to real-time mode. Most DVRs mimic this same capability.
