Simply place the alarm behind any door or window and feel safe!
This is a stainless steel cover door stop alarm. Just put the alarm under the door and turn on the switch. If an intruder attempts to open the door, the wedge-shaped design will prevent it from opening and activate a 120 dB alarm. The alarm will scare off the would-be intruder and alert you to the attempted entry.
Adjustable sensitivity switch prevents tampering. There are 3 sensitivity levels you can choose. The maximum loudness can be up to 120dB.
There is the high damping rubber at the bottom which can prevent the door sliding when any intruders attempt to enter.
