Selection of lighting systems in outdoor electrical stations working together with camera systems

摘要

When installing outdoor surveillance camera systems, a suitable choice and setting of outdoor lighting are important to ensure the right functioning of a camera and a legible and sharp picture. To these camera systems could transmit relevant visual information in the electric station is necessary correctly settings of illumination. The paper deals with the necessity to cooperate lighting system watchdog lighting and camera system and is discussed the sensitivity of cameras and their requirements for illuminance and luminance. Standard values of speed of monochrome camera chips are around 0.1 lx and for colour chips around 1 lx. Values of monochrome sensors are one digit place higher than of colour sensors so they are convenient especially for bad light conditions. Is necessary to explain that higher described illuminance are on the camera chips and not on the working places.
