For camera surveillance in industrial facilities, this CCTV solution is also suitable for hazardous areas of zones 1,2, 21 and 22. At its core is the CCTV Smart Display, a touch screen HMI system inside a field housing, which displays live images of the connected surveillance cameras. The HMI system can display the image of one single camera or a split screen for two or four cameras. A separate Smart Board unit contains control and power electronics for the cameras.
