SURVEILLANCE CAMERA WITH WIRELESS COMMUNICATION AND CONTROL CAPABILITY

摘要

A camera and a remote device wirelessly communicate data and commands over a first channel using respective wireless transceivers. The wireless transceiver of the camera is normally operated in a sleep mode. The remote device transmits a wake up signal on a second channel to a receiver in the camera, wherein the wireless transceiver in the camera is woken and communication is established over the first channel. The wireless unit on the camera is removably coupled thereto so that the cameras can operate with or without the unit.
