Portable Door Alarm, 98dB Vibration Sensor Security Device, Touch Detection Through Wood Metal and Gloves, LED Flashlight, Hang-On Design for Doorknobs Handles Window Latches, 4×2 inch Travel Size

I’ve helped countless travelers and renters find security solutions that work in temporary living situations. This Portable Door Alarm solves a problem that many people face: how do you secure a space when you can’t install permanent hardware? The answer is a device that provides immediate protection without leaving a mark.

Who This Door Alarm Is Best For:

• Frequent travelers who need reliable hotel and Airbnb room security without permanent installation
• College students in dormitories where traditional security devices aren’t permitted
• Apartment renters who want enhanced door security without violating lease agreements
• Caregivers monitoring doors to keep loved ones with dementia or special needs safely inside

Key Features: The vibration sensor technology is what sets this alarm apart from basic door contacts. While magnetic sensors only activate when a door actually opens, this device alerts you the moment someone touches or attempts to manipulate your doorknob or window latch. It detects movement through wood and metal, and even works when intruders wear gloves to avoid leaving fingerprints. The 98dB alarm is loud enough to wake you from sleep and alert neighbors without being so overwhelming that it causes hearing damage in close quarters.

The auto-reset feature is particularly valuable for ongoing threats. After sounding for 20-30 seconds, the alarm automatically rearms itself in just 3-5 seconds. If someone tries again, they’ll trigger a second alert. This prevents a determined intruder from simply waiting out the alarm. The built-in LED flashlight serves dual purposes: illuminate dark areas when entering your room, and check around your property perimeter before settling in for the night. This runs on two AAA batteries, which provide weeks of continuous monitoring.

Practical Details: Dimensions are 4″ x 2″ x 1¾” with a weight of 0.15 pounds including batteries. The compact size means it takes up minimal space in luggage but provides maximum protection in unfamiliar environments. Requires two AAA batteries (not included, available at any store). The hook design fits standard doorknobs, lever handles, and window latches without tools or adjustments. Manufactured by Safety Technology with a 1-year warranty covering defects in materials and workmanship.

Whether you’re securing a hotel room tonight or want peace of mind in your apartment, this alarm delivers instant protection without permanent installation. Be Prepared and Be Safe!
