Use a clean microfiber lens cloth to wipe the lens gently.
If there is dust, blow it off first with compressed air or a camera blower so you don't scratch the lens.
Dome Cleaning: Apply rubbing alcohol (isopropyl alcohol) to a clean microfiber cloth. Wipe both the inside and outside of the dome cover using a gentle, mini-circular motion.
For fingerprints or smudges, lightly dampen the microfiber cloth with lens cleaner or distilled water—don't spray directly onto the camera.
Wipe gently in a circular motion, then use a dry part of the cloth to finish.
Avoid paper towels, tissues, abrasive cloths, household glass cleaners, and harsh chemicals, as they can scratch or damage the lens coating.
If the camera is outdoors, check for water spots, dirt, grease, or spider webs around the lens and housing.
Make sure the lens is completely dry before checking the video quality
