Guard doors, windows and display cases in seconds. This palm-size vibration sensor sticks discreetly to glass or wood, then arms itself five seconds after you flip the switch.

At just 72 mm x 10 mm and 35 g, the unit blends into hotel rooms, flats, shops or student digs without drilling or cables.
