VISION loop sensors trigger the car alarm's siren whenever a sensor wire leading to a protected item is severed. Perfect for protecting stationary toolboxes in trucks, navigation units, audio head units, exterior performance items like spoilers, and whatever can be "removed and stolen."

Dual Purpose Functionality allows the product to act as a polarity converter for door trigger signals.
