Residential Use:

CCTV has a most convenient application for the home. A single camera can be installed at the front door, or (for example) several cameras can be installed to view :  the front door, the entrance gate, the swimming pool and the baby's room.

For the sake of security , these views can be recorded on a time lapse recorder that archives up to 960 hours on one tape.

For the sake of convenience , these camera views can be programmed onto your television's cable or antenna signal. A "modulator" will let you program the CCTV  pictures to be viewed on an otherwise unused channel.

Below is a picture, captured from a TV set,  that is viewing the front entrance of a home using their selected channel # 78.
