This window shock alarm has two sensitivity settings (high and low). It can also be used on glass door panels. The high sensitivity setting is for larger windows or door panels and the low setting is more suitable for smaller windows.

If someone tries to force or break the window, the 110dBs alarm will sound to shock and deter the intruder. As well as the loud alarm, a bright red warning sign on the self-adhesive sticker included provides a visual deterrent.
