17. Wifi Devices that Can See Through Walls

A wifi device that can see through walls?  "Researchers have devised a prototype device that can see through walls by tracking signal changes of WiFi frequency signal changes" http://blog.alexanderhiggins.com/2012/08/20/big-brother-walls-wifi-171201/.  As a new technology, its innovation and entrepreneurship in the context of the current world economic and business domains are yet to be established.  

Reported on 3 News Firstline TVNZ 30 August 2012, this device aims to be modeled for use by the Police.  The wifi device senses other electronics in the room, and reflects sonar rays from it back to the wifi device.  Any movement between these rays will be identified.  The notion that any movement sensed must be that of the attacker, (not of the victim) therefore police can fire rounds through these walls.  More information is expected on its accuracy, and efficiency.  

Its ability to detect people and items in enclosed spaces not only benefits the Police force, but defence force also. The impact this device would have for the emergency services, search and rescue operations would be resourceful and life saving, especially in highly dangerous mining disasters. 

On the other hand, identified risks raise warning bells especially where the Police are instructed to fire at the next moving target - bank robbers may decoy one of their victims into a shower of bullets. 

It is anticipated that its diffusion for our defense  emergency and police departments would be slow to begin with as accuracy, limitations, and even legalities must be defined. However predicted to rise as security industries, and other industries find use for the tool.
