Abstract:

A system, device, and method for monitoring an uncontrolled area around a mobile object uses a distributed antenna, which can be a leaky coaxial cable, enclosing its perimeter. A field disturbance sensor, such as a microwave sensor, detects an intruder entering a protected area defined by field of the antenna. An alarm signal is sent to a wireless transceiver for transmission of an alarm event to a remote station. A biometric sensor, such as a passive infrared heat detector, can be used in conjunction with the field disturbance sensor to reduce possible false alarms. Identification of a legitimate alarm may alternatively be verified with video images obtained near an area of interest in proximity to the mobile object, which may be forwarded by the wireless transceiver to a remote station for analysis.
