Video surveillance system maintenance precautions

(1) spare parts

In general, each system must maintain a corresponding spare parts store for its maintenance. It mainly stores some equipment that is more important and can not be repaired immediately after damage, such as cameras, lenses, and monitors. Once these devices fail, they may make the system unable to operate normally and must be replaced in time. Therefore, a certain number of spare parts must be available, and the inventory of the spare parts library must be constantly updated according to the characteristics of the equipment maintenance and the operating cycle of the equipment.

(2) Accessories

The accessories are mainly the additional configuration of various discrete components and modules in the equipment, and can be prepared for more, mainly used for the maintenance of the equipment. The commonly used accessories include various integrated circuit chips and various circuit discrete components required for the circuit. Other larger devices must be equipped with certain functional modules for emergency use. In this way, after maintenance, small investments can be made to produce good benefits, saving a lot of money for updating equipment.

(3) Tools and testing instruments

To repair equipment, you must configure common maintenance tools and maintenance equipment, such as various pliers, screwdrivers, pencils, soldering irons, tapes, multimeters, oscilloscopes, etc. If necessary, you should also add them at any time. Make your own simulation load as a test tool.

2. Precautions when maintaining equipment

During the maintenance of the monitoring system equipment, some situations should be guarded against as far as possible so that the equipment can operate normally. The main work is to prevent moisture, dust, corrosion, lightning, and interference.

(1) moisture, dust, and corrosion

For various collection equipments of the monitoring system, since the equipment is directly placed in a dusty environment, the operation of the equipment will have a direct impact, and it is necessary to focus on the maintenance of moisture, dust, and corrosion. If the camera is hung on the shed for a long time, the protective cover and the dustproof glass will be quickly covered with a mixture of dust, carbon ash, etc., dirty and dark, but also corrosive, seriously affecting the viewing results, but also to the equipment To damage, so you must do a good job of camera dust, corrosion protection and maintenance work. In some places where the humidity is heavy, the installation position and equipment protection must be adjusted during the maintenance to increase the moisture resistance of the equipment. At the same time, dehumidification measures must be taken to solve the moisture problem in high humidity areas.

(2) Lightning protection and anti-interference

As long as people who have engaged in the maintenance work of electromechanical systems know that thunderstorms and lightning strikes are a common occurrence and cause great safety risks to the normal operation of monitoring equipment. Therefore, monitoring equipment must be protected against lightning during the maintenance process. highly valued. The measures for lightning protection are mainly to make grounding equipment grounding grounding, and should be based on the equipotential body program to do an independent grounding resistance less than 1 ohm of the integrated grounding network, to eliminate the lightning protection system grounding and power lightning protection grounding network Mixed practices to prevent power ground grid clutter from interfering with equipment. Anti-interference is mainly to adhere to the principle of strong and weak electricity separation when wiring, separate the power cable from the communication cable and the video cable, and strictly follow the communication and power industry wiring specification construction.
