The practical signal
Spiderwebs, dust, rain debris and impact often occur on outdoor cameras. However, a blurry image can also come from moisture inside or reflection outside the lens.
advice
Cleaning camera lenses without damage
A dirty lens can disturb image and night vision, but aggressive cleaning can damage coating, sealing or housing.
The control sequence
First, check whether the dirt is really on the outer glass and look for damage, condensation, or loose sealing. Compare day and night images to determine the cause of the complaint.
What is smart to do
Use only a suitable soft method according to the camera instructions and avoid abrasive substances. Have a damaged seal or internal condensation examined instead of polishing harder.
When it is completed
Check sharpness and night vision after cleaning on the relevant route. Note recurring pollution; it may indicate a mounting spot that needs maintenance more frequently.
