it is very touchy i had to back to the place where i had it installed three time's for adjustments but it is a good thing to have i like to know when someone is close to my car or even around it

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!!

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!!

Let me start by acknowledging Amazon for providing such a deal on the sensor. The manufacturer sells this sensor at $90. I was able to add three additional sensors (radar, tilt, glass) to my system for the price of one.

I added this to my Python 872 security system. After 20 minutes of testing the sensitivity levels, I set it up just as I wanted: I have it so it will warn when standing right next to the vehicle, and it will only arm if someone enters the car (I had the window rolled down while testing for the full alarm trigger). Adds a much welcomed ability to my Security/Remote Start System. Bam.

I have DEI 508 D sensor installed in Nissan Maxima 2005 with Viper 791XW It works great, but make sure you adjust the sensor correctly (not to sensitive).
