This lightweight, easy-to-use security device transforms an ordinary doorknob into a highly sensitive burglar alarm.
Simply hang the alarm on the inside door knob, turn it on, wait 10 seconds and the unit is set.
If someone touches your doorknob (from the outside) this device will instantly emit an 85-90 dB alarm (on the inside) to scare them away and alert you to the attempted entry.
It has a sound/light selector switch which allows you to either hear an alarm or see a flashing
light when the door knob is touched.
