For CCTV systems to be effective, keeping your system in tip-top form is crucial. If your cameras are externally located, dust and grime will inevitably build up, causing poor image and false motion detection events. Spiders are also a particular concern as they are attracted to the warmth of infra-red heat.
So, how do you clean your cameras?
Safety First
Falls from height is the 3rd highest cause of fatal injuries comprising approximately 20% of all occupational deaths each year.
- If your cameras are located above your reach, select the most suitable ladder for the task.
- Ensure your ladder is on a dry, stable level surface.
- If using a fixed or extension ladder to rest against the face of a building, set the ladder to a ratio of 4:1 (for every 4 metres the ladder goes up, the foot of the ladder needs to be 1 metre away from the building.
- If you are using a fixed or extension ladder, tie the ladder to the wall using a wall plug and anchor with a ratchet strap; if this is not feasible, ask a friend to foot the ladder to avoid the bottom slipping.

What you will need
- A can of compressed air
- Glass cleaning wipes
- A microfibre cloth
Method
- First, use the compressed air to spray any excess debris off the camera and pay particular attention to gaps between the camera and the mounting surface (this is where the creepy-crawlies like to hide).
- Use a glass cleaning wipe on the lens of the camera to remove any stubborn grime.
- Use a clean and dry microfibre cloth to remove any excess glass cleaner.
- Wait a few seconds for the glass cleaner to evaporate.
- Inspect the camera lens and repeat if necessary.
If the camera lens is clouded, this is a sign that water has made its way into the watertight compartment of a camera. There is little to be done to rectify the issue safe from replacing the camera or lens.
Price of a professional camera clean
