Works great! Use it on a Viper model 5000 in my Dodge Ram quad cab. When adjusted to high it even picks up motion a few feet away from truck with windows and doors closed. It even picked up on the vibration/motion of me tossing in a tool box in the back of the bed. Odd that it indicates ‘open door’ icon on remote when it warns and/or alarms. It does show as a different zone number than the door zone.

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!!

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).

I like this adjustable field sensor for an addition to a car alarm I was very easy to plug in during the install.
