Barking sound without a dog.

This home security device is the most easiest way to thwart break ins. It just consists of a steel bar that is leaned onto the door.

When the door knob or the door itself is touched, it emits an alarm like a siren or the sound of dog bark.

So, the installation is quite easy and there is not much cost involved. It operates on a bateery. The whole device is less than $30.

Should be handy to take it along when you travel-right?
