An ordinary door wedge blocks a door leaf. It says nothing about what happens next: if someone pushes, insists, or forces it, no one knows until the door gives way. It is this silence that a door wedge equipped with an alarm addresses.
Two ways to block a door, two different logics
The portable door lock inserts into the strike plate and physically blocks the opening in silence. It is a discreet solution, designed not to disturb anyone. The alarm door wedge works the opposite way: it slides under the door leaf and triggers a 120-decibel audible signal as soon as pressure is applied to the door. One prevents, the other warns. Both meet the same need—blocking a door you don't have total control over—through two complementary rather than competing mechanisms.
What the official side says, and what it doesn't
We must be transparent on one point: no official French source consulted specifically addresses the security of a hotel room or temporary accommodation. The burglary prevention fact sheets from the Ministry of the Interior and the National Gendarmerie concern the home, and the "Operation Tranquility Holidays" covers monitoring a residence during an absence, not the vigilance of a traveler in a room that is not their own. This gap is not proof of an absence of risk; it is simply a subject that is not covered by public statistics, and it is better to say so than to invent a figure to fill the silence.
How it works
The alarm door wedge slides under any door in two seconds, on a non-slip base compatible with most floors. As soon as movement is applied to the door, the alarm triggers at 120 decibels, adjustable to three levels of sensitivity depending on whether you want to detect a simple nudge or only a determined attempt. It runs on batteries, without WiFi or an app, making it usable in any accommodation without setup.
At home too, not just when traveling
The travel reflex is the most obvious—hotel room, Airbnb, student dorm. But home use is just as relevant: the door of a teenager sleeping alone at home during a shared custody night, the bedroom of an elderly person living alone, or simply an additional door to monitor while sleeping. Unlike the portable lock, which requires an accessible strike plate, the wedge adapts to practically any door without prior verification.
What it does not do
An audible alarm does not physically hold anyone back; it warns. Faced with someone who forces it despite the noise, it does not block the door as firmly as a lock inserted into the strike plate. And if no one is within earshot, the alert is lost, as with any local alarm without a connection. It is a detection and deterrence product, not a high-security lock.
