Abstract
This invention provides a family of improvements to video security systems. In a first embodiment, a television set employed for normal television viewing is switched to be the monitor of the security system only upon the happening of a security violation event as sensed by a sensor. I one variation thereof, the switching capability is built into a dual-deck VCR along with the ability to reset the system to normal television watching by means of the remote control for the VCR. In another embodiment, the video cameras of the system are made easily adjustable and relocateable by the use of a bi-directional wireless transmission system linking the cameras to the base station and monitor. Video is sent from the cameras and control signals to adjust the field of view of the cameras are sent without the need for connecting cables. In another variation and improvement on the latter embodiment, a video camera is mounted on a mobile platform so as to be moveable and guidable to locations within a security monitoring area.
