Portable wedge-shaped door alarm with 120 dB sounder and adjustable sensitivity for home and travel security

This battery-operated door security device combines alarm protection with physical door stopping in a compact wedge design. Requiring no permanent installation, it suits temporary security needs in homes, hotel rooms, offices or student accommodation. The vibration sensor detects door movement and triggers the audible 120 dB alarm, while the adjustable sensitivity settings allow customisation for different environments. When the alarm function is switched off, the wedge serves as a basic door stop, providing dual-purpose utility from a single portable unit.

Features and Construction

This security device prioritises straightforward functionality with practical design elements that enhance its versatility across different settings.

Material and Build

The housing is constructed from ABS plastic, creating a lightweight yet durable enclosure that withstands regular use. A stainless steel cover adds rigidity and surface protection where the wedge makes contact with the door and floor. This material combination provides sufficient robustness for the intended security function while maintaining portability for travel applications.

Size and Practical Fit

Described as mini-sized, the wedge-shaped profile is engineered to fit most standard hinged doors. This compact design saves storage space when travelling and allows discreet placement under doors. The wedge angle provides sufficient resistance to hold doors partially open while allowing the vibration sensor to detect movement attempts.

Uses and Placement

The device serves multiple security scenarios where temporary or portable protection is preferred over permanent installations.

Event or Professional Use

For business travellers or event organisers needing temporary room security, the portable wedge alarm offers instant protection without damaging hotel or venue doors. The 120 dB alarm provides audible deterrence, while the vibration sensor responds to forced entry attempts. The adjustable sensitivity accommodates different door types and environmental vibrations.

Everyday Home Use

In residential settings, the device adds an extra security layer to internal doors or secondary entrances. It functions as both alarm and physical barrier, with the option to disable the alarm for use as a standard door stop. The battery operation eliminates wiring concerns, making it suitable for rental properties where permanent alterations aren't permitted.

Benefits and Buying Value

The product delivers practical security advantages through its dual-function design and straightforward operation.

Reuse and Low Maintenance

With battery power and no installation requirements, the device maintains its functionality across multiple locations and uses. The ABS and stainless steel construction withstands regular handling during travel. Battery replacement (using standard 9V batteries) represents the primary maintenance requirement.

Why Choose This Product

This door alarm addresses specific scenarios where portable, non-permanent security is preferred. The wedge design provides physical resistance while housing the alarm components, creating a compact solution. The adjustable sensitivity allows customisation for different door types and environments, while the 120 dB alarm offers clear audible warning. Its dual functionality as both alarm and door stop adds practical value for various security needs.
