Why we don't sell motion detector driveway alarm sensors.

It's very simple.  They are not dependable.  

 

We have tested several motion detector driveway patrol sensors and we have found that they send false signals.  They ring when there are no vehicles in the driveway or worse, don't ring at all even when a vehicle has entered the driveway.  These monitor alarms can produce false signals like when a leaf falls from a tree, cats or dogs cross their path, and sometimes even when the wind blows.  We have received several calls from frustrated owners of motion sensor driveway alarms who need our assistance in getting a dependable driveway notification system.  The owners of these passive infrared (PIR) sensors often describe them as "Cheap plastic toys".

The most reliable driveway alarms use the black rubber tubing to send the signal to the bell.or transmitter.  These are the only systems that we sell at www.MiltonsBells.com.  These drive-thru monitoring systems are physically activated each time a car or truck compresses the driveway signal tubing.  This simple design has been around for 50-70 years depending on the type of system and many of these bells have been continuously working, with some regular maintenance, for 40+ years.
