What do you think of glass break detectors for a home alarm system? I’m also getting each outside door wired.

the way glass break detectors work is that you put one within twenty feet or so from your windows and they are designed to only alarm when one of three types of glass are broken within their range, the three types are tempered, laminate and plate glass. they work well if you get the right brand. i know from my job that g.e. makes a really good one and they are wireless. there are also the kind of glassbreak detectors that you put directly on the glass and they alarm when the window glass is vibrated but they tend to false alarm due to wind blowing, cars with loud stereos etc. on a side note, very few burgulars will break a window and drag themselves through broken glass, so when they break a window, it is usually just to reach inside and open it so if whoever is wiring your doors is charging a certain amount, wiring the windows may be cheaper than the glassbreak because window contacts and door contacts are cheaper than glassbreak sensors. hope this helps

Layla is correct regarding the application of glass break detectors. I recommend both window and glass break detectors. This will detect both modes of entry. If locks or pins are installed on the windows to make glass breakage to gain entry necessary then you can eliminate the need for window contacts.
Motion detectors would be the most cost effective solution if you don’t occupy the area when the alarm is armed. Be advised that when a motion detector trips the intruder is already inside. A combo glass break/window contact design is more expensive but will detect an intruder before entry.
I recommend at least one motion as a secondary layer of protection in the event the intruder circumvents the perimeter.
I also recommend alarm monitoring. How many times have you called the PD when you heard an alarm sound? I am guessing you figured it was just another car alarm………..
