Monitoring system monitoring system consists of the monitoring system software, monitoring host, front camera, composed of three parts, transmission line transmission line into the video, feet line transmission, power transmission systems, control line transmission. Maintenance Equipment Overview: 1. an industrial-type hard disk recorders, installed system windowsXP, configuration 512 RAM, 17-inch display, the current user is equipped with 14 cameras in use. 2. Monitoring software comes with a 16-channel monitoring software, its main functions include monitoring, recording, image capture, video playback, monitoring software is currently set different permission levels in order to prevent non-account management operations. 3. The front of the camera is divided into two types: 3.1 Video line transmission Camera: The camera lens control signals are directly connected to the control room, the camera power transformer for the front (~ 220V turn DC12v) supply. 3.2 twisted road Camera: The camera lens is attached to the control signal after Balun turn is connected to the control room, the camera power transformer for the front (~ 220V turn DC12v) supply. Surveillance camera manufacturers to share the recipe to help you solve the problem of camera surveillance cameras camera Backlight basic condition is smooth light, smooth light sensitive CCD cameras will allow uniform backlighting has been shooting taboo, when the backlight brightness, and background compared to the object being photographed will appear dark, easy to form a shadow home installation of monitoring systems, will result in more intense backlighting is too strong degree subject is underexposed. First, through the choice of having the corresponding functions surveillance camera surveillance camera manufacturers to install monitoring systems to improve backlighting phenomenon. The second contract to install monitoring systems, surveillance cameras installed to adjust the position of the entrance, try to avoid direct sunlight from the outside world, can improve the phenomenon largely backlit entrances. Third, by increasing the interior light source illumination, improved backlight phenomenon.
