Maintenance / Cleaning

How Often Should Outdoor Security Cameras Be Cleaned?

There is no useful universal cleaning interval. A sheltered camera in a dry location may stay clear far longer than a camera beside a road, tree, sprinkler, salt air or insect-heavy light source.

Use the image as the trigger. Clean when day or night footage shows haze, flare, IR reflection, water spotting, dust, webbing or insects that reduce evidence quality.

Inspect both day and night

Compare current image sharpness with a known-good reference frame.
At night, look for halos or bright fog caused by residue, webs or objects reflecting infrared close to the lens.
Check whether leaves, new growth, signs or seasonal decorations now obstruct the scene.
Inspect the housing, mount and cable entry while you are already at the camera.

Cleaning method

Follow the camera manufacturer’s cleaning instructions. In general, remove loose debris gently before wiping optical surfaces, use a clean soft lens-safe cloth, and avoid abrasive cleaners or methods that can scratch a dome or damage seals. Do not aim high-pressure water at connectors, seals or the camera body.

After cleaning, verify evidence

Do not stop at “the lens looks clean.” Check live video, then review a fresh daytime and nighttime recording. Confirm focus, field of view, timestamps and motion/event behavior are still correct.
