This unique, bargain-priced, yet effective, GLASS BREAKAGE ALARM is an effective low-cost vibration alarm that can be used for securing windows or doors wherever you find yourself.
The glass alarm can also be used as a personal property alarm to protect computers, TVs, stereos, cabinets, et cetera. This comes with one 12V battery and strong adhesive tape so you can affix it wherever you want.
Then you turn the switch located on the side, to the ON position. When the glass is hit, kicked, knocked upon, or even broken by anyone, the siren will sound for approximately 30 seconds and then shut off and reset. This is great for an apartment, a dorm room, a hotel or motel room, or any room in your house. The convenient dimensions are 2″ x 2 1/2″ x 1″ and this faithful little beauty just goes to show you that you may not necessarily have to spend “big money” to have some safety and security, as well as “peace of mind.” So, people with any budget, can still have some protection these days.
