Security robot "Trawl Patrol 5" is designed to replace patrolling guards in closed protected areas. Wheeled robot moves around the object without the operator, stopping in a predetermined, optimal for observation, points of the route. At the same time, if the circular video surveillance system detects motion, the computer of the video analysis system induces a rotary camera into the motion area. If the figure of a person is recognized on the detailed image of the rotating camera, the robot gives an alarm signal to the security post, and the guard, having examined the image, decides on further actions: reset the alarm, turn on the siren or strobe light on the robot, or personally proceed to the place of penetration and deal with the offender.
