Door Stoppers

A door stop alarm is a portable security device that combines the function of a physical door wedge with an electronic alarm system. Its core structure typically includes a wedge-shaped blocking component and a high-decibel siren. When an external force attempts to push open the secured door, the mechanical component creates a physical barrier, while a built-in sensor triggers the alarm system to emit a warning sound exceeding 100 decibels. This type of device primarily serves users in scenarios such as frequent business travel, solo living, student dormitories, and short-term rentals. It is particularly suitable for situations requiring temporary door security where permanent installations are not feasible. Product variants mainly include three types: portable wedge-style, adjustable bracket-style, and suction cup-mounted. Some advanced models also feature vibration-sensor activation, flashing LED warning lights, or smartphone app connectivity. Its key distinction from traditional door locks is the complete absence of drilling for installation. Utilizing a pressure-sensing mechanism, it offers instant, tool-free use. It represents a lightweight personal security solution that integrates both physical deterrence and audible alarm capabilities.
