Ex Zone Surveillance
The new EX270 dome from Hernis is engineered specifically with correct optical rendering in mind. The design allows for an astounding 36x zoom without mentionable image distortion. In poor lighting conditions the camera will automatically turn to black and white for optimal image quality. Autofocus increases the user comfort further.
The dome offers endless panoramic rotation and a 180deg tilt with vertical image flip. Speed; 116 degrees pr second. Tooth belt operation reduces risk of mechanical wear out failures. Optional interfaces are RS422, 232 and 485. The customized glass is electro- magnetically compatible (EMC). In practice this means that any extra safety measurements during cleaning in Ex zones are now rendered superfluous. A hard coating on the glass adds scratch resistance.
The new dome will be delivered in accordance with international standards. Already effective is EX certification by DNV to ATEX Directive 94/9/EC, certified as Ex II 2 G Ex d IIB + H2 T6.
Like other Hernis camera stations, the EX dome is designed to meet the DNV requirements for Type Approval Certification. The EX270 may be used with any Hernis CCTV control system and can be mounted standing or hanging depending on the viewport required
