Monitoring of the front-end equipment and back-end equipment, which consists of two major components, front-end equipment is usually composed of cameras, manual or motorized lenses, PTZ, shields, monitors, alarm detectors and multi-functional decoders and other components. Installation of monitoring equipment is as follows:
1, the first to determine the location and number of monitoring installation, the number of wires to use, the number of hard disk recorders, such as parameters, to determine the corresponding equipment parameters and list, to the nearby technology market to install the list of equipment for procurement.
2, after the completion of equipment procurement, first according to the previous design of the camera installation location and monitoring host installation location for wiring, there is a ceiling where as far as possible from the ceiling on the side of the line, do not leave open wires. There is no ceiling place can be used wire pipe or wire channel, beautiful and generous.
3, line laying is completed after the start of the previously designed point of installation of surveillance cameras and 12V power supply, surveillance cameras need to be fixed camera bracket and self-tapping wire, at this time you need to use an impact drill first in the wall wall holes, stuffed with a good up plug, with self-tapping wire fixed camera bracket. Then install the camera to the bracket gimbal.
4, front-end monitoring equipment is installed, but the installation of back-end equipment. The first program uses a video capture card, the video capture card is installed into the supermarket computer PCI slot, the use of computer hard disk for video storage.
Expanded Information:
The typical TV monitoring system is mainly composed of front-end monitoring equipment, transmission equipment, back-end storage, control and display equipment, which consists of five major components, of which the back-end equipment can be further divided into the center of the control equipment and sub-control equipment. Front and back-end equipment has a variety of ways to constitute the link between them (also known as transmission system) can be achieved through cable, fiber optic, microwave and other ways.
Many efforts have been made to overcome the shortcomings of thermal radiation infrared lamps, the first is the development and application of high-pass infrared filtering tempered glass. The longer the wavelength, the smaller the red storm, and can even achieve the full absence of red storm, however, the lower the efficiency of infrared light, infrared lamp heat is higher. The wavelength of the infrared glass can be selected according to the user's requirements for the high and low red storm.
Generally speaking, the same effective irradiation distance, the higher the red storm requirements, the higher the cost. Infrared glass after toughening, can withstand rapid changes in cold and heat, in the internal infrared bulb due to visible light filtered out of the part, the conversion of the heat generated, the temperature will be very high, the external cold winds and rain and snow under the sudden attack, the rapid cold and not damage.
In order to improve the life of the heat radiation infrared lamp, the use of light-controlled switching circuit, in order to reduce its working time; the use of a variable voltage regulator rectifier circuit, so that its luminous power to give full play to and improve the life of the infrared lamp.
