Pixel Paradox makes NO claim that STOP THIEF will prevent any kind of criminal activity whatsoever, under any circumstances. It has NO ability to detect motion, or call the police. Everything is FAKE. It is comparable to "the electronic barking dog", which is not really a dog, but just a recording of a barking dog. DO NOT RELY ON THIS PRODUCT TO PROTECT YOUR PROPERTY, OR OFFER ANY KIND OF HOME SECURITY.
