Abstract: A system for transmitting and receiving communication messages in a wireless security system is provided. The security system comprises one or more security sensor devices and a receiving device. Each security sensor device is capable of monitoring a status change in an area and is capable of generating and transmitting a communication message at a first frequency and a communication message at a second frequency based on a change in status of the area being monitored. The receiving device capable of receiving the communication messages from the one or more security sensor devices and in response thereto is capable of generating one or more instruction signals based on the communication messages. A security sensor device of the one or more security sensor devices transmits the communication message at least one time at the first frequency and the communication message at least one time at the second frequency.

Abstract: A device and method for monitoring whether a resident is away from home or inactive within the home. A sensor, which includes a transmitter, a processor, a timer, and a detector, watches for motion to occur within a home. Upon sensing motion, the sensor sends a first signal indicative of the motion if the timer is not currently running and waits for the motion to end. If the timer already is running, the timer is restarted at zero. Upon expiration of a predetermined timing period, the sensor transmits a second signal indicative of inactivity. By comparing the timing of the second signal and the predetermined timing period, with a third signal sent by an exterior door sensor, a determination can be made whether the resident has left the home or is inactive within the home.
