A British company has invented a new camera that can see weapons, drugs or explosives under people's clothing from up to 80-feet away.
The Thruvision company developed the T5000 camera device to combat terrorism. They say it could be used in crowded airports, shopping malls and at military installations.
Company officials say the camera does not reveal any physical details and is harmless to people. They explain that it's a key way to enhance security.
"Acts of terrorism have shaken the world in recent years and security precautions have been tightened globally," said Clive Beattie, the chief executive of ThruVision. "The ability to see both metallic and non-metallic items on people out to 25 meters is certainly a key capability that will enhance any comprehensive security system."
But critics are worried that Britain is just becoming a surveillance society. Hundreds of thousands of closed-circuit cameras monitor people every day throughout the entire country.
How Does it Work?
The camera uses imaging technology to identify objects by the natural electromagnetic rays, known as Terahertz rags, or T-Rays that they emit.
The technology behind camera works on the basis that all people and objects emit low levels of electromagnetic radiation. Researchers say Terahertz rays are somewhere between infrared and microwaves on the electromagnetic spectrum and they travel through clouds and walls.
Each piece of material has its own unique wave. Therefore explosives can be distinguished from a block of clay and cocaine will appear different from a bag of flour.
