1. Achieve the "Four Qi", that is, complete spare parts, complete accessories, complete tools, and complete instruments.
Complete spare parts: Generally speaking, the maintenance of each system must establish a corresponding spare parts library, mainly to reserve some more important equipment that is not easy to repair immediately after damage, such as cameras, lenses, monitors, etc. Once these devices fail, the system may not operate normally and must be replaced in time.
Complete accessories: accessories are mainly the additional configuration of various discrete components and modules in the equipment, and more can be prepared, mainly used for equipment maintenance. In this way, a small investment can be used to produce good benefits after maintenance and save the cost of updating equipment.
Tools and testing instruments are complete: In order to repair the equipment frequently, it is necessary to configure the commonly used maintenance tools and overhaul instruments, such as various pliers, screwdrivers, electric test pens, electric soldering irons, tapes, multimeters, oscilloscopes, etc., and they should be available at any time when needed. Add, if necessary, you should also make your own such as simulated load as a test tool.
2. Some things to pay attention to in equipment maintenance
Moisture-proof, dust-proof, and anti-corrosion: If the camera is hung on the end of the shed for a long time, the protective cover and dust-proof glass will soon be covered with a mixture of dust, carbon dust, etc., which is dirty and black, and is corrosive, which will seriously affect The viewing effect also brings damage to the equipment, so it is necessary to do a good job of dust-proof and anti-corrosion maintenance of the camera. In some places with heavier humidity, it is necessary to adjust the installation position and equipment protection to improve the moisture resistance of the equipment itself. At the same time, dehumidification measures must be taken to solve the moisture problem in high humidity areas.
Lightning protection and interference prevention: The surveillance camera system has the characteristics of high density, low voltage and low power consumption of the original components, and is very sensitive to various electromagnetic interferences such as lightning overvoltage, power system operating overvoltage, electrostatic discharge, electromagnetic radiation, etc. This makes the surveillance system equipment extremely vulnerable to lightning strikes. Therefore, the surveillance camera system must attach great importance to lightning protection during the maintenance process. Lightning protection is a more complicated issue. The design of lightning protection for the monitoring system not only depends on the performance of the lightning protection device, but more importantly, before the design and construction of the monitoring system, it is necessary to consider the geographic environment where the monitoring system is located. , Design appropriate cable routing, shielding and grounding methods. In short, the design of lightning protection should be considered comprehensively to obtain good results. Anti-interference is mainly to adhere to the principle of separation of strong and weak electricity when wiring, separate power cables from communication cables and video cables, and construct in strict accordance with the wiring specifications of the communication and power industries.
3. Pay attention to details in daily maintenance work
Perform dust removal once a quarter to clean the dust on the surveillance camera system, remove the camera, protective cover and other components to thoroughly blow the dust, and then wipe the lens with anhydrous alcohol cotton to adjust the sharpness to prevent the machine from running and static electricity. Factors such as suck dust into the body of the surveillance camera system to ensure the normal operation of the machine. According to the operating instructions of each part of the monitoring system, check its technical parameters and the quality of the transmission line of the monitoring system every month to deal with hidden troubles.
A comprehensive inspection of the surveillance camera system components that are prone to aging shall be carried out once a month. Once aging is found, it shall be replaced and repaired in time, such as the video head.
