I. Cleaning Cycle under Normal Environments
1. Quarterly: Suitable for indoor or relatively clean environments (such as control rooms, office areas, etc.), effectively preventing dust accumulation from affecting image quality.
2. Each cleaning should be combined with overall equipment maintenance, simultaneously checking the lens cover's seal, infrared lamp status, and lens coating integrity.
II. Increased Cleaning Frequency Required for Harsh Environments
1. Monthly: Suitable for the following high-risk scenarios:
2. High-dust environments (such as coal mines, grain silos, cement plants): Dust easily adheres to the lens surface, affecting light transmittance;
3. High-humidity or acid/alkaline environments (such as chemical plants, coastal areas): Moisture and corrosive gases can cause lens fogging and coating corrosion;
4. Outdoor open-air locations (such as oil depot perimeters, port terminals): Long-term exposure to rain, fog, and carbon ash mixtures easily leads to stubborn stains.
✅ It is recommended to record changes in image clarity after each cleaning to establish a maintenance record for tracking equipment health status.
III. Precautions Before and After Cleaning
1. Before Cleaning: Ensure the equipment is powered off and operate in a safe area to avoid sparks;
2. After Cleaning: Check if the IP66 protection rating has been restored, and confirm that the O-ring seals are intact and the wiring ports are secure;
3. If fogging, coating peeling, or ineffective wiping are found on the lens, stop using it immediately and return it to the factory for repair. Do not disassemble it yourself.
