Three level detector signal for multicamera video alarm system for remote monitoring and method

A surveillance system for radio transmission of surveillance information from a first location to a second location, comprising:

• a plurality of cameras mountable at said first location in a plurality of different positions, said plurality of cameras being operable to produce a plurality of video signals;
• a plurality of motion detectors, respective of said plurality of motion detectors being positioned in a known relationship for association with respective of said plurality of cameras whereby when a respective motion detector is tripped then a respective camera is indicated, at least one motion detector being mounted at a mounting position entirely separate from and spaced apart from a mounting position for an associated camera;
• an encoder comprising a plurality of video inputs;
• a radio transmitter to transmit surveillance information comprising said plurality of video signals from said first location to said second location;
• a radio receiver to receive said surveillance information at said second location;
• a decoder at said second location that decodes said surveillance information comprising data representative of which of said plurality of motion detectors have been tripped and which have not been tripped;
• and a monitor at said second location connected to said radio receiver, said monitor being operable to display a particular video from a plurality of videos of said surveillance information based on an alert signal;
• said plurality of cameras comprising an encoder video camera, said encoder video camera being mounted to an enclosure wherein a plurality of LEDs is mounted to said enclosure, said LEDs being responsive to said plurality of motion detectors to indicate which of said plurality of motion detectors have been tripped and which of have not been tripped, said encoder video camera mounted to said enclosure and being positioned to produce an encoder video showing which LEDs are activated, each LED producing three levels of brightness comprising a bright level, a dim level and a black level, said black level being an indication of malfunction;
• said encoder camera being interconnected with said plurality of cameras to produce said plurality of videos, wherein said plurality of videos and said encoder video is transmitted to a second location, wherein said decoder decodes said encoder video to determine which of said plurality of motion detectors have been tripped.
