Xeravos DoorGuard turns any inward-opening door into a security checkpoint. Slide the steel wedge under the door, switch it on, and if anyone tries to push the door open, a piercing 120dB alarm goes off instantly — while the wedge digs in to help hold the door shut.

Why you'll love it

  • Instantly loud. A 120dB siren — as loud as a rock concert — wakes you and startles an intruder the moment the door moves.
  • Zero installation. No drilling, no wiring, no apps. Place it and switch it on.
  • 3 sensitivity levels. Low, Medium or High to match your door and floor.
  • Built to travel. Compact and lightweight for hotels, Airbnbs, dorms and business trips.
  • Two in one. Switch the alarm off and it works as a regular doorstop.
  • Long battery life. One 9V battery lasts up to a year under normal use.

How it works

  1. Insert a 9V battery.
  2. Set the sensitivity level.
  3. Slide it under the door, tip first, and turn it on.
  4. Sleep easy.

FAQ

Before you
pack it.

Any door that opens inward, toward you — which covers most hotel rooms, apartments, bedrooms and dorms. It isn't designed for outward-opening or sliding doors.

No. Each alarm uses one standard 9V battery, available at any store. Under normal use a battery lasts up to a year.

Yes — set it to High sensitivity on thick carpet, Medium on thin carpet or wood, and Low on smooth tiles to avoid false alarms.

It's compact and lightweight, so it packs easily in a carry-on or checked bag. We recommend removing the battery while traveling.

Absolutely. Switch the alarm off and it works as a sturdy everyday doorstop to hold doors open.

Two Xeravos DoorGuard alarms per pack — one for home and one for your travel bag.
