Abstract: Methods and devices for a wireless security controller that is able to receive data transmissions over multiple frequency channels and decode security messages that use different data protocols is provided. The security controller monitors an incoming security message transmission from a security sensor. As the transmission is received, the security controller analyzes the data, and determines whether is encoded using one of two or more different transmission protocols. The security controller then completes reception and error-checking of the received security message, and processes the security message.

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.
