Wireless Vibration Alarm with Remote, Door and Window Siren

A compact stand-alone alarm for doors, windows, cabinets, bicycles or storage boxes. Stick or fix it to the surface you want to watch; when it senses vibration it sounds a loud siren. The two-button key-fob remote arms and disarms it, so you can open the door yourself without setting it off. No app, hub or wiring is needed. Black plastic housing. The supplier lists a 9 V operating voltage. In the box: one alarm unit and one remote control.
