A closed-circuit TV camera is often described as a camera in a light bulb because the tiny device can be easily screwed into a light socket with the inside actually being a highly sophisticated low-light monochrome camera. The camera has a video signal that is encoded and processed directly to a 110-volt power line and has a decoder that can be plugged into a regular home television set. It uses standard video output with line-level RCA-type cables. The built-in infrared system has the capability to see a maximum of 30 feet in total darkness. It is durable and works well using lengths of AC wiring up to 2000 feet. A camera is compact and light in weight, and shows live, encoded feeds. Home usage, with power lines also pulling electricity for refrigerators, air conditioners, heaters, etc, is good and delivers good, clear images. Wide-angle viewing, door entrances and exits, parking lots, etc, is best with Closed Circuit TV cameras and is usually the best choice for surveillance.
