Abstract
A passive actuation of a home security system incorporates a sensor for sensing movement of a vehicle approaching the home security system. When such movement is detected, a signal is sent to a control for the home security system. The home security system generates a challenge response which is received by a transmitter/receiver associated with the vehicle. The vehicle transmitter/receiver receives the challenge response and sends its response to the challenging control. The vehicle response is received by the control for the home security system and compared to an expected response. If the two match, then the home security system is actuated. The system may be utilized on garage door openers, fences, home locks, etc.
