The LaserScan security system doesn't really do anything at all, but it does impersonate a heavy duty alarm, and that's the important thing. The only thing that this security system does is scan the room with fancy-looking laser beams. These laser beams look like they are protecting a expensive diamond ring in a museum, but in reality they do absolutely nothing.
The idea behind the LaserScan security system is that robbers will get too scared to even attempt to steal from you if they see these laser scanners. Basically, this security system acts like a guard dog sign with a much higher price tag. It seems that the best option may be a security system that scans your home and also calls the police.
