Central radar based alarm system, for monitoring buildings and rooms without external sensors

摘要

The central unit has an integral sensor (4) rotatable about 360[deg]. This detects and stores the contours of the building and its surroundings in defined angle steps. In each cycle, the monitoring system compares and analyzes a new contour. The scanned area is scanned several times during one 360[deg] rotation of the system. The detected signal is transmitted to a data transmission unit with information on angular velocity and size.
