The U.S. Transportation Security Administration will test new heat-sensing cameras that can be used to screen people at a train or bus station without requiring a mandatory wait at a security checkpoint.The 10-inch cameras can be placed anywhere in a station, where they will be able to screen people as they walk by. The cameras can take a thermal image of the body from up to 20 yards away, highlighting materials colder than body temperature, signifying objects such as metals, plastics and ceramics.
Experts are sceptical about the cameras, claiming that the technology is not advanced enough and will result in the search of innocent people. ‘
