Portable Door Alarm 98dB with Vibration Sensor – Travel Security Device, Hotel Room Protection, Emergency LED Flashlight

You’re staying somewhere that doesn’t feel completely secure. Hotel room, Airbnb, dorm, temporary housing. The locks work, but you want that extra layer of awareness — something that tells you immediately if someone tries to come through that door while you’re sleeping or away.

This alarm is built for people who travel frequently, live in shared housing, or stay in places where they can’t modify the existing security. Business travelers who cycle through hotels. College students in dorms. Anyone renting short-term housing. If you need reliable door security that sets up in seconds and travels in your bag, this handles it.

The decision is simple: you want door security that doesn’t require installation, works instantly, and alerts you the moment someone tries to enter. This alarm wedges under any door, detects both opening motion and vibration, and delivers a 98dB alert that wakes you up and makes intruders back off. Battery-powered, portable, and ready when you need it.

Legal in all US states as a personal security device. Operates on one 9V battery (included). Works on doors that open inward with at least 1/2 inch clearance at the bottom.

Frequently Asked Questions

How loud is 98dB compared to everyday sounds?
About as loud as a motorcycle engine or power lawn mower. Loud enough to wake you from deep sleep and alert people in adjacent rooms, but focused enough not to disturb an entire floor of a hotel.

Will this work on all types of doors?
Works on any door that opens inward with floor clearance. Most hotel rooms, dorm rooms, and residential doors work perfectly. Won’t work on doors that open outward or have extremely tight floor seals.

How sensitive is the vibration detection?
Calibrated to detect deliberate door manipulation — someone trying the handle, picking the lock, or forcing entry. Normal building vibrations or people walking by won’t trigger false alarms.

How long does the battery last?
Several months of regular use. The device only draws power when actively alarming, so standby battery life is excellent. Always test before each trip to confirm the battery is working properly.
