SECURITY MOTION SENSOR AND VIDEO RECORDING SYSTEM

A combined alarm and surveillance system integrates an existing alarm system (12) with an existing surveillance system (14) such that functions unique to each system are combined in a complementary manner. The existing alarm and surveillance systems are combined via an interface (16) comprising an array of electric relays (52,54,56,58,60,62). Each relay receives a signal from either the alarm system or the surveillance system and retransmits the signal to the other system in a form that is compatible with the receiving system. The alarm system is configured to communicate alarm status information to the surveillance system, and the surveillance system is configured to communicate control signals to the alarm system, such as an alarm system reset signal.
