Protect your vehicle with an invisible sensing field which detects moving high-density objects (including people) near your car using Radio Frequency (RF) field disturbance technology. Ideal for convertibles, or any application where zone-intrusion protection is desired. Violation of the outer field can provoke siren chirps (or a WarnAway message from an optional voice module) while intrusion into the inner zone will trigger the system’s siren.
Q: Could this be mounted under vehicle carriage to deter catalytic converter theft? Is it 12 volt
A: Yes, it is 12v. It would be better mounted inside the car, under the carpet as it is NOT waterproof or weather resistant.that should still give coverage around the catalytic converter and keep it working for a long time.
A: To the best of my knowledge as a low voltage electronics technician, the answer is yes, you need to have the "brains" or controller for this add on device. Power and signal transmission comes from the controller. The controller interprets the signal coming from the unit. Keep in mind that is not a true motion detector. It reads disturbances in the field that it generates, both in the vehicle and around the vehicle. By trial and error you will find what settings work best for you. We found, that in order to keep false alarms to a minimum, we had to really dial down on the sensitivity. If you want a true motion detector ( they don't really detect motion, just rapid changes in temperature in the area that they are looking at, floor heaters have a habit of activating motion detector alarms). Then I would get a 12vdc small motion detector either on-line or from an electronics store. A motion detector really doesn't do much unless it activates a relay or switch that causes something else to happen - like flashing lights, siren or whatever.

A: This was s replacement for a 15 year old sensor that was a bit flaky. However Best buy did the install for my first one and they made it accessible so I could replace it easily if I needed to. If you cant get through on the phone, go to Best Buy and speak to the install techs in person. I have had the same issue with the phone but I always have no problem if I go in person.
