Monitoring in hazardous areas

Thanks to the individual design of its CCTV systems for Ex zones 1, 2, 21 and 22, R. Stahl guarantees reliable monitoring and detection of potential ignition sources and sources of fire.

To optimally adapt the systems to the conditions on site, the company carries out plant inspections and accompanies its customers from the conception to the commissioning of the CCTV system. R. Stahl 's camera technology prevents costly false alarms.

The new IP thermal imaging cameras in the EC-840S-TIC series are able to detect flame movement and temperature independently of each other. They measure temperatures with pixel precision to monitor production areas of up to 650m2 and only trigger the programmed alarm sequence when predefined temperature values are exceeded.

Efficient surveillance concepts can be implemented in conjunction with the fast pan-tilt-zoom (PTZ) cameras. The PTZ cameras are able to precisely focus on control points and objects within 0.2 s and reproduce them in excellent quality. In addition, IP PTZ cameras with dynamic masking also take data protection into account, as this feature can be used to make people, moving objects and areas that should not be displayed unrecognizable. The S, T and Q profiles of the open protocol standard ONVIF ensure simple network integration of the cameras and uncomplicated data provision for all relevant persons. The cameras are certified in accordance with ATEX, IECEx, NEC, CEC, EAC and Lloyd's and, depending on the type, are approved for use in temperature ranges from -50 to 65 °C.
