Mini Wireless Vibration Triggered Wedge Shaped Door Stopper Alarm

Description:

Simply put, the alarm can be installed behind any door. The wedge-shaped configuration prevents the door from opening and activates a 120 dB warning if an attacker tries to open it.

The alarm will scare away the would-be intruder while also alerting you to the intrusion attempt. Tampering is prevented by a sensitivity switch that can be adjusted. Simply chuck this compact device into your luggage while traveling. The unit’s on/off switch keeps it from unintentionally sounding.
