Access to camera images and remote control from HMI stations

23 July 2009

R. Stahl is introducing a CCTV complete solution for safe and hazardous areas that can be integrated in plant control systems. The ActiveX and OPC software interfaces are used to fully integrate the cameras. The camera signals can then be easily incorporated into process images and can be displayed at any operating station, from where the video equipment can also be directly operated. Cameras, software solutions and HMI systems can be supplied as a complete package including all accessories.

Access to camera images and remote control from HMI stations

Three camera types are available for installation in hazardous areas. The pan/tilt EC-730 is an autofocus camera. Its 22x zoom is supplemented by an 11x digital zoom function for extreme magnification. The EC-730 is suitable for ambient temperatures ranging from -30 °C to +50 °C and also has a seawater-proof aluminium housing. Thanks to its zero-lux night vision mode the camera can also be used in very dark environments. The second model is the extremely compact, spherical EC-710-090 which, due to its diameter of only 55 mm, fits into the smallest spaces. The fixed camera viewing angle is +/- 90° horizontally and 68° vertically. Although the EC-710-090 weighs 435 g, its steel housing can withstand aggressive chemical substances and protects the camera from substantial mechanical stress. It can be installed in ambient temperatures ranging from -30 °C to +75 °C. Located under a transparent dome, the third Ex-protected camera is the EC-750, which gives users maximum flexibility, particularly for an all-round view. With a tilt angle of ±90° it can freely pan across 360°. It has an 18x zoom lens. This intelligent model can follow up to 64 programmable positions and paths.
