I. Daily Cleaning Methods
1. Lens Cleaning
Use a soft cloth (such as a non-woven fabric) dampened with anhydrous alcohol or a specialized lens cleaner and wipe the lens surface in the same direction to avoid scratching the coating.
Stubborn stains can be pre-treated with a nano-coating spray to reduce dust adhesion. Clean once a month.
2. Explosion-proof Cover and Sealing Ring
Remove the cover regularly and blow out any accumulated dust inside with compressed air. Clean the sealing ring with an alcohol wipe to prevent grease and deterioration.
Do not use sealing putty to replace the factory sealing ring, as this will compromise the explosion-proof performance.
II. Key Points for Advanced Maintenance
1. Moisture-Proof, Dust-Proof, and Corrosion-Proofing
In high-humidity environments, install a dehumidifier and check that the device is installed in a location that facilitates heat dissipation.
In environments with corrosive dust (such as chemical plants), the cleaning cycle should be shortened to once a week. 2. Electrical Safety
Check the sealing of the cable entry and ensure the compression nut is tightened. Do not combine multiple wires into a single hole.
<1Ω) before thunderstorms to prevent weak and strong currents from sharing the same ground.
III. Intelligent Cleaning Solution
1. Automatic Cleaning Device
A visibility sensor and MCU-controlled automatic cleaning system can be installed. This system triggers the cleaning motor by monitoring image clarity.
This system is suitable for high-risk areas such as oil tank farms where manual maintenance is difficult.
2. Preventive Maintenance
Monthly inspect vulnerable parts such as cooling fans and DVRs. Increase ventilation measures during hot weather.
Deteriorating components (such as cameras) should be replaced promptly to avoid safety hazards caused by equipment failure.
IV. Precautions
Prohibited Behavior: Unauthorized disassembly of equipment, modification of internal wiring, or filling of sealed cavities.
Professional Operation: Maintenance of explosion-proof structures must be performed by certified personnel in accordance with manufacturer specifications.
