Batteryless Sensor for Intrusion Detection and Assessment of Threats
Abstract
A new series of security sensors has been sucessfully developed by ANRO Engineering, Inc. (ANRO) to detect intruders, and signal a remote alarm without batteries, external power or wiring. These wireless and self-powered (WASP) sensors are inherently covert both in the installation and presence of the sensor, and the low probability of intercept/detection (LPI/D) wireless link. Demonstration models have been constructed for hidden placement in existing doorknobs, doorjambs and windows. The operation of the sensors is not discernible to an intruder, and does not depend upon the speed of activation. A wireless link was developed that operates within the FCC Part 15 for unlicensed oepration, as well as within the guidelines for frequency allocation for many government facilities. The wireless link uses a coded signal to discriminate between more than 1024 sensors within an area. ANRO was particularly successful in keeping the cost of the sensors as low as possible. The cost of the components that are added to the lockset in a doorknob, for example, is estimated to be under $5. This new WASP sensor technology can be applied to keyless lock systems used in secure facilities and storage containers, and for commercial applications such as keyless hotel doors.
