This is a great sensor if you have a Air tight car
This is a great sensor if you have a Air tight car I have this sensor in my mini van with the 2 sensors over my 2 front pillar I have them set at max and have no problem with them as long as all windows are closed tight no Air flow in the car I have test this sensor in every way I have open my driver window and set the alarm and it will not last a min and the alarm is set off I have put a stuff doll on my dash and set the alarm with all windows closed and rock the car to the doll drop off the dash and set off the ultrasonic sensor this sensor is 100% I have set the alarm and open a back lift gate and the ultrasonic sensor was set off I even open the back vent window 3 out of 5 times the sensor will see the air flow from the vent.
