The mechanism, which the NYPD is developing with help from the U.S. Department of Defense, currently only works at a short range of three or four feet. But [NYPD Commissioner Ray ] Kelly thinks they can improve it to scan citizens from a distance of up to 25 meters away. He announced this morning that the gadget will be mounted on NYPD vans with "the infrared rays shooting up the street at the person," as the Post puts it.
The device detects the radiation emitting from a personís body, and it can't penetrate metal, so a concealed gun can be spotted from the image captured by the detector's lens.
In the 2006 movie Ultraviolet, the police make use of scanners placed at security portals to determine whether or not an individual is carrying weapons, and if so, how many. (Skip to about 1'10" to hear the quote, start from the beginning for stylish ultra-violence.)
Daxus - "How much weaponry does she have left?"
Daxus Aide 1 - "Based on scans taken from the security portal..." [pause'
Daxus Aide 1 - "...plenty."
Daxus [takes a deep breath]
