Just recently bought a pager car alarm system. Now i want to upgrade some options such as the auxiliary microwave and ultrasonic sensor. Which am i better off with the auxiliary or microwave since i already have the glass breakage. I also wanted to know if theres a sensor that detects if your wheels have any movement such as someone trying to steal my rims?

 

you can add on a tow sensor where if you car is jacked up the alarm will sound

 

^^thanks will definitely look into that

 

Yes you can rig it to work. Most alarms go off negtive triggers to sound the alarm. Most after market add ons give negtive triggers to set off the alarm. It there is a problem with polarity just use a relay to switch it.
