 FAQ video surveillance video surveillance is an important part of the social security system of law and order, it is a comprehensive system of prevention ability. Video surveillance system has been used in various fields of its intuitive, accurate, timely and rich information content and widely used in many occasions. In recent years, a contract to install monitoring systems, along with computers, networks and the rapid development of image processing, transmission technology to install monitoring systems, video surveillance technology has made leaps and bounds. Because of its weak system is mainly composed of electronic equipment, systems problems arise during installation, use. To users and works to cause unnecessary trouble. To improve work efficiency, and ensure the normal operation of the monitoring system, combined with a rich source maintenance monitoring system maintenance experience, the monitoring system of common problems, as described below DVR can not control PTZ possible reasons: 1, the front-end PTZ failure 2 PTZ decoder setup, connection, installed incorrectly 3, DVR 4 PTZ settings are not correct, PTZ decoder and DVR protocol mismatch 5, when connected to a plurality of decoders, PTZ decoder AB line The most distal need to add 120 ohm resistor to eliminate reflections and impedance matching, otherwise it will create instability 6 PTZ control, real-time image problems too far away, such as video image color, brightness distortion and serious surveillance camera manufacturers to share the recipe to help you solve The basic conditions for camera surveillance cameras camera backlight problem is smooth light, smooth light sensitive CCD cameras will allow uniform backlighting has been a taboo shooting in backlit, when compared with the brightness of the background, the object being photographed will was relatively dark, easy to form a shadow, backlit subject too will result in more intense degree of underexposed. First, through the choice of having the corresponding functions surveillance camera surveillance camera manufacturers, improve backlighting phenomenon. Second, adjust the installation of surveillance cameras installed entrance position monitoring system manufacturers, try to avoid direct sunlight to install monitoring systems cost from the outside world, can improve the phenomenon largely backlit entrances. Third, by increasing the interior light source illumination, improved backlight phenomenon.
