120dB Door Stop Alarm with Vibration Sensor and Three Sensitivity Levels for Home Security

This compact door stop alarm combines a physical wedge block with a powerful 120dB electronic alert to help secure your home, office, or hotel room. The vibration sensor detects any attempt to open the door, sounding a loud alarm that deters intruders and alerts occupants. With three sensitivity settings, you can adjust the device to suit different door types and levels of foot traffic. The stainless steel cover adds resilience, while the lightweight design (94g) makes it easy to carry when travelling.

Features and Construction

Built around a simple but effective concept, this alarm uses a vibration sensor and a loud piezoelectric siren to provide reliable entry detection. The wedge shape ensures a secure fit under most doors.

Sensitivity Settings

Choose from high, medium, or low sensitivity to match your environment. High sensitivity catches light door movement, ideal for quiet spaces; low sensitivity reduces false triggers in busy areas.

Stainless Steel Cover

The outer casing is made from stainless steel, offering better impact resistance than plastic-only alternatives. This helps the alarm withstand accidental knocks and repeated use.

Size and Portability

Measuring just 14 x 4.5 x 3.5 cm and weighing 94g, the alarm fits easily into a bag or pocket. Its compact footprint means it does not obstruct door operation when not in use.

Uses and Placement

This device is designed for any inward-opening door where you want an extra layer of security. It works in residential and commercial settings alike.

Home Security

Place it under front doors, back doors, or bedroom doors to alert you to unexpected entry. The wedge block also makes it harder to force the door open.

Travel and Hotel Use

Lightweight and battery-powered, it is ideal for hotel rooms, hostels, or rented accommodation. Simply slide it under the door and activate the alarm for portable peace of mind.

Office or Shared Spaces

Use it on meeting rooms, storage closets, or private offices where you want to control access. Adjust sensitivity to avoid false alarms from normal building movement.

Benefits and Buying Value

This alarm offers an affordable, non-permanent security solution that requires no installation. Its low maintenance and reusable design provide ongoing value.

Battery-Powered Simplicity

Powered by a standard 9V battery (not included), the alarm has no wires or mounting hardware. Battery life depends on usage, but a single battery typically lasts many weeks under normal conditions.

Reusable and Portable

Unlike adhesive or screw-fixed alarms, this wedge unit can be moved from door to door in seconds. Take it with you when you move home or travel.

Why Choose This Product
