A British company has developed a camera that can detect weapons, drugs or explosives hidden under people's clothes from up to 25 meters away in what could be a breakthrough for the security industry.The T5000 camera, created by a company called ThruVision, uses what it calls "passive imaging technology" to identify objects by the natural electromagnetic rays -- known as Terahertz or T-rays -- that they emit.
The high-powered camera can detect hidden objects from up to 80 feet away and is effective even when people are moving. It does not reveal physical body details and the screening is harmless, the company says.
If this is real, it seems much less invasive than backscatter X ray.
