Customer Reviews

Dual Zone Sensor
Works very good. You can hide the sensor so it`s undetectable. I have a Jeep with a Soft Top. This sensor was perfect for interior protection.

it works but hard to find sensitivity medium
it definitely works. dont get me wrong, but im still trying to find the medium where it just chirps when u walk by or up to the vehicle, & goes off if bumped. its set now to go off when bumped somewhat hard, & chirp if just pushed. its weird because its either too much or too little. the turning mechanisms are not that wide so you have to try again & again to find the sensitivity you want. or be blessed enough to find an alarm tech to install it & set the sensitivity perfect the first time... but it does the job!!

Outstanding!!
This little clear box is an unbelievable add-on for a security system. You can change the field radar to surround your car. My garage door sets it off when it opens. It is a very touchy add-on that will help protect your car!!
