Invisibeam® Field Disturbance Sensor508D

Protect your vehicle with an invisible sensing field which detects moving high-density objects (including people) near your car using Radio Frequency (RF) field disturbance technology. Ideal for convertibles, or any application where zone-intrusion protection is desired. Violation of the outer field can provoke siren chirps (or a WarnAway™ message from an optional voice module) while intrusion into the inner zone will trigger the system’s siren.

This device is good if you have a convertible or plan on leaving your windows down. . . Nice if you own the car but if you are an installer it gets to be annoying when customers have to come back to your shop 2-4 times before reaching the right level of sensitivity either it’s too sensitive and tree blowing in the wind sets it off or you put your arm in the car and only the warn away chirp comes on. . . once they are set correctly with the dual zones they work great but would not recommend them in just any car.

Have this installed in my S2000 convertible. The module intself sits right below the center console behind the cup holder. This is a MUST for convertibles. As soon as I reach into the car or hover my hand over the soft top the alarm goes off. Sometimes it can sense tree leaves but it will just trigger the warn away and not the full alarm. Overall this product is very good and will give you piece of mind on the convertible.

I owned this on my 2G AWD Talon. I wanted the outer field to trip causing the alarm to chirp if someone was looking inside the car. It works well until it rains and then rain drops rolling down the windows start to trip the outer field. The inner field works very well after it is properly set, but it takes a few tries.

This works great i have it in a 95 mustang...its not a convertible but after many hours of playing with it i have it set just right ...i feel it can be used for cars just take your time getting it to the right point of triggering it...how ever it dose have one big down fall!! ....living in Michigan it snows,and yup u guessed it i small layer over ur car or melting off your car will set it off every time with this ...other then that its great
