ABSTRACT:
An intrusion detector system employing a remote, 360.degree. infrared detector. The system includes a base unit with a receiver, controller, and phone jack, a remote sensor which is adjustable along a vertical axis and includes a 360.degree. infrared motion sensor, and a central monitoring station in communication with the base unit via a telephone network. The remote sensor may be selectively positioned to detect movement in a surrounding area definable by the user. The base unit may be programmed to contact the monitoring station when the sensor detects motion, and also to receive test signals from the monitoring station and verify that the system is operational.
