HomeSafe Glass Breakage Alarm
This Glass Breakage Alarm will let you know anytime someone knocks, breaks, or hits your window or door glass as it senses vibrations. It includes a 12-volt battery and very strong adhesive tape. Turn on the switch and there will be a 100 dB siren sounding for about 30 seconds when the alarm is activated, and then it will shut off and reset itself. It’s also great for protecting personal property.
