Smart Door Stop Security Alarm

Sleep safely anywhere. This portable door stop alarm gives you an instant layer of security in any room — hotel, Airbnb, apartment, or office. When someone tries to force the door open, it triggers a piercing 150dB+ alarm that stops intruders in their tracks.

No installation needed. Just slide it under the door. When pressure is applied from the other side, the built-in sensor activates the alarm within milliseconds.
