WHO R U / Burglar Alarm


Prevention is better than cure.
“Who R U” is different from usual alarm system that making a alert sounds when burglar opens the door.
It is trick device which has a fake indication that makes your place safety from burglar.
If burglar touches your door while you're away, it sounds.
"Who are you?"

It sounds a ready recorded voice when sensors in the doorknob are touched.
Seems like somebody present!
Also you can record sound of TV or barking of the dog.

It could do the prevention of the crimes perviously with urgent request to a police station or a guardhouse when sensors in the doorknob are touched three times over.
