Why is my motion sensor not working properly?
There are models that have better circuitry not to trigger for small power bumps and some have sensitivity adjustments these are the 2 nuisance issues I have found. These units also detect heat changes. Make sure the HVAC vent isn’t blowing warm or cool air onto the detector or into its view of the space.
What should I do if my car alarm goes off for no reason?
This is usually one of the reasons why car alarms go off for no good reason. You will need some brake cleaner, a cleaning brush, and a microfiber towel for this. Locate where the hood latch sensor is, you’ll usually find this near the headlights.
Can a motion sensor turn on a light?
I have a movement sensor (PIR i presume) that turns on a light when movement is detected. Annoyingly it turns on without reason; even when noone is in the house.

Why does my far left parking sensor go off?
Image Search… Just today my front far left sensor started going off constantly when I go at low speeds. Doesn’t stop. I think it is mainly because of the weather/wind. The sensor is directly where the wind is coming from. Started this morning. I tried cleaning it but really there wasn’t anything to clean off.

When does the car alarm go off on a Mercedes?
Mercedes alarm may go off even when no one is trying to steal the car. We have seen many cases when a Mercedes alarm (siren) goes off during the night while the car is parked, when you try to lock the car or during extremely cold weather. This past week we worked on a Mercedes-Benz where the alarm would go off randomly in the middle of the night.
