1. An intrusion detector comprising:
- a base unit including an electromagnetic wave receiver programmable controller in communication with said receiver; and
means for indicating an alarm condition; and
at least one remote sensor including a base and a sensor head vertically displaced upwardly from said base, said remote sensor further including an electromagnetic wave transmitter for communication with said base unit, a 360°
infrared motion sensor disposed in said spherical sensor head and in communication with said transmitter, and means for adjustably fixing the relative positions of said base and said sensor head such that the height of said sensor head may be adjusted along a vertical axis, wherein, upon sensing of motion by said infrared sensor, said transmitter transmits alarm signals to said receiver, said controller being programmed to activate said alarm indicating means when said alarm signals are received.

Abstract
An intrusion detector system employing a remote, 360° 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° 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.
