Abstract

There is disclosed an antitheft security alarm system and method for manhole covers, rainwater drains, and the like, to prevent burglary of the cover by transmitting a wireless alarm signal to a remote station when the cap is removed to notify a dispatch center or other notification message recipient of the burglary incident and location. The security apparatus may be an integrated unit, including sensors, a telemetry unit, a power supply, a processor, and supporting hardware, all located in an enclosed, waterproof housing. The security alarm system apparatus is adapted to fit within a manhole cavity without the need for extensive or alteration of existing manhole structures.
