This door stop does not only block your door from being opened, if anyone would try to open the door it will set off a 125 decibel loud alarm.
The 125 dB Door Stop Alarm ($15) features a movement sensor with adjustable sensitivity that activates the alarm. You can activate/deactivate the feature with the on/off switch.
The DSAL-2 door stop uses one 9-volt battery (not included).
