Commercial Security Camera Maintenance Checklist

A camera system only helps if it works when footage is needed. This checklist covers the checks that keep a commercial camera system working — the cameras, the recorder, the storage, the software and the remote viewing.

Camera Checks

Check every camera live, and confirm that each one is recording — a camera can show live video and still not be recording. Check the image quality of each camera, in daylight and at night. Check that each camera is aimed where it was designed to point, and that its mount is secure.

Outdoor cameras need extra attention: check the housing for water ingress, the lens for dirt and insects, and the mount for looseness. A camera that has moved a few degrees may be watching a wall instead of a doorway.

Lens and Mount Care

Clean the lenses, especially outdoors, where dust, rain spots and insects degrade video gradually. Check the mounts for looseness, and check that the camera has not been knocked out of position. A clean lens and a secure mount are the simplest maintenance there is, and they make the largest difference to video quality.

Check the housing seals on outdoor cameras. A seal that has failed lets moisture in, and moisture fogs the lens from the inside. A fogged lens cannot be cleaned from the outside, and the camera will need to be opened or replaced.

Recorder and Storage Checks

Check the recorder's status screen: which cameras are connected, which are recording, and whether any drives report errors. Check the drive health, because hard drives in a recorder run constantly and wear out. Check the storage capacity and the retention period, to confirm the system keeps the days of footage the business expects.

Check that playback works, and that a clip can be exported. A system whose export does not work will only be discovered when footage is actually needed, which is the worst time to find out.

Software and Remote Viewing

Update the firmware and recorder software when updates are available, and check that the system still works after the update. Test remote viewing from a phone, on a mobile connection, from outside the property. Check that user accounts are current, and remove accounts for staff who have left.

Check the alerts, if the system uses them. Motion alerts should fire when they should and stay quiet when they should not. An alert that fires constantly will be ignored, and an alert that never fires is not working.

Keeping a Record

Each maintenance visit should leave a record: the date, what was checked, what was found, and what was done. Over a year or two that record shows patterns — the camera that keeps failing, the drive that is near the end of its life, the outdoor mount that needs replacing. Those patterns are how a business plans replacements instead of reacting to failures.

The record also shows that the system is being looked after, which matters when footage is needed for an incident. A system with a maintenance record is a system that can be trusted; a system without one is a system that may or may not work.
