1、 In the maintenance of security monitoring equipment, it is necessary to focus on dust prevention, moisture prevention and anti-corrosion, and regularly clean the dust exposed by the equipment. The camera and protective cover components need to be removed and thoroughly cleaned, and then wipe the lens with anhydrous alcohol cotton to prevent dust from being sucked into the equipment due to machine operation, static electricity and other reasons. To ensure the normal operation of the equipment.

2、 Pay attention to check the ventilation and heat dissipation of the machine room, regularly check the aging parts, and find problems in time for maintenance and replacement.

3、 The hard disk video recorder needs to be maintained on time. If too much heat is generated due to long working hours, it may lead to fan failure, which will affect the heat removal problem and make the video recorder unable to operate normally.

4、 At ordinary times, we should master the operation status of security monitoring equipment and system and analyze the operation situation, so as to find problems and eliminate faults in time.

5、 Finally, in the maintenance of monitoring equipment, one thing that needs special attention is lightning protection. As for lightning protection, it is mainly necessary to do a good job in the lightning protection grounding grid for the corresponding grounding of the equipment, and prevent the lightning protection grounding of the weak current system from mixing with the power lightning protection grounding grid, so as to prevent the interference of the clutter of the power grounding grid to the equipment.
