I had one of these Dual zone perimeter protection alarms on one of my cars, the kind where you get close to it it chirps and if you stuck your hand through the window the car alarm went off. The biggest problem was temperature change, the hotter it got the bigger the area it protected and when it got cold the area it protected shrunk so small you actually had to almost put your hand on the glass to activate the chirp. This really didnt matter too much because the car got stored for the winter months, notice i did say it didnt matter too much. The worst part was when people would walk past the car on a really hot day and activate the chirp, they were not even close to the car sometimes. And dont even park near a tree with low branches because this also set it off. It was a continuous battle getting the perimeter protection fine tuned. Also you couldnt leave the car packed with anything because this interfered with the protection. I just posted this so others can know the downfall of this type of protection.
