What Kind of Picture Do Time-Lapse VCRs Record?
Actually, it’s a pretty good one and you’ve most likely seen an example of it on TV. One of the problems with leaving a VCR on and recording all the time is that someone has to review a lot of tape to see what happened while they were away. A time lapse VCR can be set up to trigger and record at real-time speeds when a contact sensor trips. It can be programmed to change recording speeds from time-lapse mode to real-time OR from standby (where the recorder is on but not recording) to real time mode when a sensor is tripped. The amount of time the VCR records at real-time speed when tripped is programmable. Most folks set it up to record for two minutes following a sensor trip.
