Vehicle alarm and theft deterrent system

摘要

This is a system for preventing vehicle theft that can be activated and deactivated from a touch-tone phone. The alarm activation code and alarm deactivation code are capable of activating a plurality of switches through the feedback loop. When the car is stolen, the owner can activate the signal code, which will disable the engine once the thief turns off the engine. After the stolen car is restored, the owner can deactivate the engine-disabling code and drive the car as usual.
