The front-end equipment for security monitoring, such as camera, protective cover, distribution box, control box and other equipment, shall be exposed outdoors for a long time, and the security monitoring system shall be maintained regularly. Daily monitoring, maintenance and management of monitoring and security monitoring shall be carried out, and equipment maintenance services shall be undertaken to ensure the long-term, reliable and effective operation of the monitoring system. In addition to daily maintenance, various collection equipment for monitoring and security monitoring shall also focus on anti moisture, dust and anti-corrosion maintenance.

1. Regularly dust and clean the monitoring equipment, sweep the dust exposed by the monitoring equipment, remove the camera, protective cover and other parts, thoroughly blow and dust, and then wipe each lens with anhydrous alcohol cotton to adjust the definition, so as to prevent dust from being sucked into the body of the monitoring equipment due to machine operation, static electricity and other factors, so as to ensure the normal operation of the machine. At the same time, check and monitor the ventilation, heat dissipation, dust purification, power supply and other facilities of the machine room.

2. The monitoring equipment components that are easy to aging shall be comprehensively inspected once a month. Once aging is found, they shall be replaced and repaired in time, such as video head.

3. For the easy dust collection part of security monitoring, clean it regularly every quarter. If the monitor is exposed to the air, a lot of dust will be adsorbed on the monitor surface due to the electrostatic effect of the screen, affecting the definition of the picture. Wipe the monitor regularly and check the color and brightness of the monitor.

4. The monitoring equipment that works for a long time shall be maintained regularly once a month. For example, the hard disk video recorder will produce more heat if it works for a long time. Once its electric fan fails, it will affect the heat removal, so as to avoid the abnormal operation of the hard disk video recorder.

5. Monitor the operation of security monitoring and equipment, analyze the operation, find and eliminate faults in time.

6. According to the operation instructions of each part of the equipment for security monitoring, detect its technical parameters and monitor the quality of the transmission line for security monitoring every month, deal with potential faults, assist the monitoring center to set the use level and other data, so as to ensure that each part of the equipment has good functions and can operate normally.

7. Optimize security monitoring and equipment on a monthly basis.

8. During the maintenance of security monitoring system equipment, it is necessary to do a good job in moisture-proof, dust-proof, anti-corrosion, lightning protection and anti-interference.

9. Moisture proof, dust-proof and anti-corrosion

For various collection equipment for monitoring security monitoring, because the equipment is directly placed in the dust to improve the moisture-proof ability of the equipment itself, at the same time, dehumidification measures should be often taken in high humidity areas to solve the moisture-proof problem.

10. Lightning protection and interference prevention
During the maintenance of monitoring equipment, great attention must be paid to lightning protection. The lightning protection measures are mainly to do a good job in the lightning protection grounding grid for equipment grounding. An independent comprehensive grounding grid with ground resistance less than 1 Ω shall be done according to the equipotential body scheme, and the practice of mixing the lightning protection grounding of weak current system with the power lightning protection grounding grid shall be avoided, so as to prevent the interference of power grounding grid clutter to the equipment.
