Door Stopper Security Alarm with 120 dB Sensor

Compact Door Stopper with Built‑In Security Alarm

Enhance entryway security at home, in the office, or while traveling with this Door Stopper Security Alarm Sensor. Combining a physical door wedge with a motion‑triggered alarm, it helps deter unauthorized entry and provides an instant audible alert. The integrated sensor activates an alarm of up to approximately 120 dB, with three selectable sound levels (low, medium, high) to suit different environments and noise sensitivities.

This unit can be used as a quiet door stopper or as an active security alarm. In door stopper mode, simply switch the alarm off at the back of the device and position it under or just behind the door to help prevent it from opening fully and to protect walls from doorknob impact. In alarm mode, switch the unit on and place it a few inches behind a fully closed door. Any attempt to open the door will press down on the wedge, triggering the loud alarm and drawing immediate attention to the entry point. The device is powered by one 9V battery (not included) and is available in multiple colors (pink, green, blue) to match your preference.
