ALARM SIGNALING METHOD INCLUDING USE OF VIDEO SURVEILLANCE Russian patent published in 2005 - IPC

FIELD: property protection technologies.

SUBSTANCE: alarm signaling device is used to detect an attempt of unsanctioned action against protected object and appropriate alarm message is generated with identification signs and location parameters of current alarm signaling device. Then by radio alarm message is sent to adjacent alarm signaling device, and relayed further to other alarm signaling devices until received by user equipment. On receipt identification signs and position parameters of source alarm signaling device are selected. Using said position parameters flight route is set and unmanned aircraft is launched, made with possible horizontal movement according to set program, video surveillance of segments of protected object, compression and transmission of received video frames by radio to user equipment. Previously, in training mode, launches of unmanned aircraft are performed along radial routes under route angles, matching shortest distances from user equipment to alarm signaling devices position points, and series of received video frames are recorded to memory of onboard complex of aircraft. When receiving an alarm message from one of alarm signaling devices commands for controlling flight of aircraft to it along set route and commands for stabilizing it according to flight parameters are formed by combined correlation processing onboard the aircraft of current and prerecorded video image frames, appropriate for radial flight route of unmanned aircraft to current alarm signaling device.

EFFECT: higher efficiency, broader functional capabilities.
