To ensure the imaging quality and service life of the surveillance lens, it is essential to avoid scratching the mirror surface or damaging the coating during the cleaning process. The following outlines professional cleaning procedures and precautions:
I. Preparations Before Cleaning
1. Power Off: Ensure that the monitoring equipment is completely powered off to prevent accidental contact or liquid infiltration.
2. Dust Removal: Use an air-blowing bulb or compressed air canister to remove loose particles from the lens surface. It is recommended to position the lens downward or sideways during this process to prevent dust from resettling on the surface. This step is critical to avoid abrasive particles causing scratches during wiping.
II. Selection of Cleaning Tools
1. Cleaning Fabric: Use only microfiber cloths or specialized lens paper. Avoid using fibrous or lint-releasing materials such as tissues or cotton towels.
2. Cleaning Agent: Only use dedicated lens cleaning solutions. The use of cleaning agents containing alcohol, ammonia, or fragrances is strictly prohibited, as they may damage the protective coating of the lens, leading to light spots or image distortion. For persistent oil stains, a neutral detergent diluted at a ratio of 1:10 may be used as an alternative.
III. Cleaning Procedure
1. Application Method: Apply the cleaning solution onto the cleaning cloth rather than directly onto the lens surface. Wipe gently in a spiral motion from the center outward; avoid aggressive back-and-forth rubbing.
2. Removal of Stubborn Stains: For persistent stains, apply a small amount of cleaning solution locally and wipe repeatedly with controlled pressure. Be cautious not to use excessive liquid, which may seep into internal components.
3. Final Inspection: Use a clean, dry cloth to absorb any residual moisture, ensuring that no streaks, water marks, or scratches remain on the lens surface.
IV. Special Precautions
1. Cleaning Frequency: It is recommended to clean the lens every 3 to 6 months. Excessive cleaning may accelerate wear on the lens coating.
2. Outdoor Equipment: After cleaning, inspect the waterproof seals and rubber gaskets to ensure proper sealing and prevent water ingress.
3. Prohibited Actions: Do not attempt to disassemble or clean the internal components of the lens without authorization. Additionally, avoid using breath to moisten the lens, as this may promote mold growth. If internal fogging or blurring occurs, contact a qualified technician for assistance.
V. Common Mistakes to Avoid
1. Avoid using generic household cleaning agents or alcohol-based solutions.
2. Do not wipe the lens surface without first removing loose dust.
3. Do not disassemble the lens or attempt internal cleaning without professional authorization.
4. Avoid using breath to moisten the lens surface for cleaning purposes.
