1.2GHz Wireless 380TVL CMOS 15M Night Vision Security Camera Silver WN-701

Wireless cameras are a combination of three components: A camera, a transmitter to send the signal, and a receiver to receive the signal. A Wireless Camera transmits video from a built-in transmitter to a receiver, which is in turn plugged into either a monitor or other recording device.

Wireless cameras come all shapes and sizes and are capable of transmitting to different distances. The transmission range of a Wireless Camera is usually rated by use the Line-of-Sight (LOS). Standard Wireless Video Cameras have a range of about 700 feet LOS. The signal can be transmitted through most solid objects including glass, plastic, wood, fiberglass, and some metals, but the signal is attenuated. So the actual transmission range depends on the number and type of objects you are transmitting through, such as brick walls, concrete walls, trees, etc. An ordinary 700 ft. LOS Covert Camera can typically transmit signal through about 6 interior walls with ranges up to 300 feet and is designed to work comfortably in a building up to 6,000 square foot (home or office).

High resolution video transmission and outdoor medium range potential makes 1.2 GHz wireless video systems a good choice for multiple system applications. 1.2 GHz makes a huge difference in the range and quality of video image received, especially when going through ceilings, floors and most walls. In an unobstructed site with no other electrical interference, you can expect to clearly transmit up to 300 feet.
