Mandatory

This is my favorite sensor on my alarm. You can adjust the sensitivity of this sensor to your specific needs. I have this sensor on a large 4 door truck and it picks up everything that I want it to.

Extra Protection

If your looking for that extra protection. This is an excellent add on to your DEI security system. It provides two shock points when your car is armed. Easy installation.

Good product / good value

Good value for this motion detector, and it works perfect.
