Outdoor power stations CCTV systems that work synergistically with the security lighting

Abstract

At present time, in the operation of the outdoor electric power stations providers access their unattended operation. Linked to this there is necessary to know what is happening in the station not only during the day, but especially at night. Since the operation of the entire lighting system in normal operation is highly uneconomical and generates light pollution too, the solution is that in permanent night operation is only lighting system providing illumination around the fence for security cameras and for visibility of the borders of power station from outside. Synergistically with this type of lighting should be set up security cameras system providing information about potential disruption perimeter of the power station. The article deals with the proper selection and mutual synergy of outdoor lighting systems and security cameras system. The issue is not only in the power stations, but generally in using of the cameras systems in industrial applications which are dependent on artificial lighting. Main chapters of the article will solve following problems. At the beginning it is necessary to describe the need to choose the color of light of artificial lighting system to spectral sensitivity of chips inside the cameras. It will continue with recommending for a design of artificial lighting system with respect to the placement of cameras. It means the design which calculates not only with horizontal illuminance, but cameras (vertical) illuminance too. The camera illuminance is necessary for recording of images the whole distance between the luminaires. The whole policy of illumination for cameras must be re-evaluated compared to standard public lighting systems design. In the last part of this article will be described relations between the horizontal illuminance, the camera illuminance, luminance and illuminance on the camera which are given by manufacturers.
