Have you ever felt uneasy about an intruder while you're home alone or staying in a motel?
Now, simply position this Door Stopper Security Alarm behind any door or window for guaranteed safety.
‘ON’ Mode - Door Stopper Security Alarm: When the alarm is activated, applying pressure to the door will trigger a loud 120db siren. This efficiently helps alert homeowners or renters, deter intruders, and potentially notify neighbors for added security.

‘OFF’ Mode - Non-Skid Door Stopper: In "off" mode, this device serves as a standard damping rubber door wedge, keeping the door propped open without making any loud sounds.
3 Sensitivity Levels: Low - Medium - High, with three sensitivity settings available via an adjustable switch on the side. The highest sensitivity level will trigger the alarm with any vibration.

Simple Installation: This door stopper alarm requires no wiring. It operates with a 9 V battery (not included). Just place it under the door. The height between the door's bottom and the floor should be about 0.38 in to 1.35 in. It will not slip on tiles, wood floors, carpets, or concrete. The H-type sensitivity is recommended for smooth surfaces.

Lightweight and Portable: This product is lightweight and easy to transport. It's perfect for use in bedrooms, hotels, apartments, dorms, or front doors. Excellent for travelers or anyone spending the night in a new location.
