A theft detection system and method for detecting the unauthorized movement of an article or assembly from a given location, such as in the act of theft or burglarizing a home, office, store or warehouse. Detection of such unauthorized movement or theft may be made at a remote location, such as a monitor station particularly when such movement is detected beyond predetermined bounds or limits. The system involves the short wave transmission of code signals which are indicative of the identity of the article or assembly and/or the location of its unauthorized movement.

A theft detection system comprising in combination with a movable object to be protected against theft, said system including; first means for detecting the motion of said object when said object is moved away from an at-rest location, said first means including means for generating analog electrical signals which are indicative of the motion of said objects from and beyond said at-rest location, second means for receiving said analog signals and digitizing same to generate digital signals representative of said analog signals, third means including electronic computing means for receiving the digital signals generated by said second means and generating control signals, fourth means for receiving said control signals and operative to generate code signals, fifth means for short wave transmitting said code signals, sixth means including short wave receiving means for receiving said short wave transmitted code signals, and seventh means including an alarm means connected to said short wave receiving means for receiving and using the code signals received thereby and generating an indication of an attempt to move said object from said at-rest location.
