This General Electric Surveillance System provides a simple yet effective way to monitor (using audio and video) your home or small business. It includes two black-and-white, high resolution video cameras with 60 ft. of cable each and a 12 in. black-and-white monitor. Very simple to install and to operate: no technical experience necessary. You simply mount the two cameras on a table, wall, or ceiling, run the included cable to the monitor, and connect a VCR (not included) to the monitor if you wish to record. The two small (they measure only 3 X 1 1/2 inches) high resolution cameras include a wide angle lens, built-in microphone to transmit sound to the monitor, and night vision capability which allows viewing up to 10 ft. in the dark. The 12 in. monitor can operate in one of three modes: camera one, camera two, or auto switching between cameras one and two. In the auto switching mode, the switch time can be adjusted from two to twenty seconds using a slide switch on the front of the monitor. You can also adjust the volume, brightness, contrast, and vertical hold. Great for monitoring customers and employees in a store or to keep an eye on the yard, garage, playroom, baby, etc. at home.
