Features and Construction

Material and Build
The alarm unit is constructed from ABS plastic, chosen for its light weight and structural rigidity to house the internal components safely. A stainless steel cover provides a durable external layer, protecting the main body of the device. This material combination results in a robust product suitable for repeated placement and removal from under doors.Size and Practical Fit
Described as a mini size, the alarm is compact to save space and enhance portability. Its defining feature is the wedge-shaped base, engineered to fit securely under the gap of most inward-opening, hinged doors. This design ensures immediate contact with the door, allowing the integrated vibration sensor to detect movement effectively without any need for screws, adhesive, or permanent installation.Uses and Placement

Event or Professional Use
Everyday Home Use In a residential setting, it offers added peace of mind for ground-floor windows or doors, children's rooms, or dormitories. It serves as a secondary security measure that is visually obvious to potential intruders. When the alarm function is switched off via the power button, the wedge shape allows it to function as a standard door stop, holding a door ajar or fully open, providing everyday utility beyond its security role.Benefits and Buying Value

It avoids the permanence and wiring of installed systems, offering a practical solution for those who need security on the go or in temporary lodgings.
