Covert RFID Video Surveillance
Das RFID Journal berichtet über das Covert RFID Video Surveillance System nox der Firma SimplyRFID.
A handful of government agencies and private companies such as electronics suppliers are employing a clandestine RFID system known as NOX that allows them to use RFID interrogators hidden in walls, in conjunction with video surveillance and, in some cases, luminescent dust, to thwart theft or other unauthorized activities within their facilities. (…) The optically charged dust consists of microporous fibers that glow when exposed to low-power laser light. This luminescence is not visible to the human eye but can be detected by a video camera. The dust is scattered in areas where there is a risk of unauthorized activity, or where entry is generally forbidden. A camera can be programmed to watch for any dust that a person might inadvertently pick by walking through an unauthorized area. When that individual passes in front of the camera, it detects the glow as the dust is illuminated by a laser and triggers an alarm.
