How Do Wireless Surveillance Cameras Work?
As the name suggests, wireless CCTV (WCCTV) cameras require no cables or wiring to send data. WCCTV technology uses microwaves in the form of radar, radio, or lasers to transmit the camera signals to a remote location-a radio receiver, a DVR, your PC or laptop, or wherever else you’d like to view the images. For short-range transmissions (to a police van around the corner, for instance), a WCCTV camera may beam the signal point-to-point-that is, straight to the receiving device. For longer distances, the signal goes by way of satellites, ground-based antennae, GSM phone networks, or even ADSL.
