Time lapse VCR
These record directly to standard videotape. Various models are available to record over time periods varying from 24 to 960 hours. A standard VCR can only record one video channel; but multiple channels can be recorded by the addition of switchers or multiplexers.
The analogue VCR has been the standard method of recording for many years, and is now joined by Digital recorders.
These utilise PC technology and record the footage to a Hard Disk or DVD. Some systems also use CD/RW and /or Digital Audio Tape (DAT) for archive purposes. Digital recorders are available as single channel or multi channel products, thus eliminating the need for a separate multiplexer.
Systems employing many cameras require a means of selecting and displaying the footage from the required camera on a particular display monitor.
These generally used in small, low cost applications. A manual switcher allows users to select the required camera by pressing an appropriate button. These devices can also switch from one camera to another automatically, or on receipt of an alarm.
Large CCTV systems, employing many cameras and monitors, will require a means of distributing the footage to the selected monitors and recording devices. This can be achieved with a Matrix Switcher. With multiple keyboards, several operators are able to control the system at the same time.
