Abstract
An unattended sensor is provided for use in a surveillance system. The sensor is generally comprised of: a detector; a signal processor; a radio transceiver; a power source; and a controller which configures the sensor in either a sensor mode or a relay mode. When configured in the sensor mode, the detector and signal processor are operational and the transceiver is non-operational. When configured in the relay mode, the transceiver is operational but the detector and signal processor are non-operational. In an alternative approach, the detector and the signal process may remain operational in the relay mode.
