what are people's opinion on glass breakage sensors? I've had one guy say that it's pointless because the shock sensor handles it.
(They are a microphone that listens for the high pitched sounds of metal on glass.) They work well if adjusted right. With that said a well adjusted 2 stage shock sensor will do the same. have your first stage set to warm away with light taps... then the 2nd stage to only go off with large hits or opening doors etc.
I had many "false" alarms with my glass breakage... even as simple a dog barking or a whistle... (epspecially if the wondows are dows a bit) for the summer heat.
Alarms are geat and most do what they are designed to do it is the person who is not telling teh installer what exactly they want out of the alarm and getting the settings right.
Some people don't want their alarms going off unless the car is gettingbroke into while other owners want thir alarms going off as soon as some one looks at their car the wrong way.
It's all in adjustment... Hope some of this rambling makes sense...
