Intrusion detector
First Claim
1. A remote sensor for use with an intrusion detection system of the type including a base unit having an electromagnetic wave receiver, a phone jack, a digital dialer, an external power supply plug, and a programmable controller in communication with said receiver, said jack and said dialer;
- said remote sensor comprising;
a base having an upwardly extending first neck portion and a spherical sensor head having a downwardly depending second neck portion for telescopic connection with said first neck portion, 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 fixing the relative positions of said telescopic first and second neck portions such that the height of said sensor head may be adjusted along a vertical axis.

Abstract
An intrusion detector employing a remote, 360° infrared detector. The detector includes a base unit with a receiver, controller, digital dialer and power supply plug, a remote sensor which is adjustable along a vertical axis and includes a 360° infrared motion sensor, and a hand held remote control unit to arm and disarm the base unit. The remote sensor may be selectively positioned to detect movement in a surrounding area definable by the user.

19. An intrusion detector comprising:
-
a base unit including an electromagnetic wave receiver;
a programmable controller in communication with said receiver; and
means for indicating an alarm condition; andat least one remote sensor including a base having an upwardly extending first neck portion and a sensor head having a downwardly depending second neck portion for telescopic connection with said first neck portion, said remote sensor further including an electromagnetic wave transmitter for communication with said base unit, a 360°
infrared motion sensor disposed in said sensor head and in communication with said transmitter, and means for fixing the relative positions of said telescopic first and second neck portions 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. - View Dependent Claims (20)
