A CCTV system that isn't maintained is decoration. In our experience, most camera failures aren't dramatic — they are silent. A lens cakes up with dust, a hard drive quietly fills to capacity, a camera drops off the network and nobody notices for weeks. Then something happens — a break-in, a dispute with a delivery driver, a missing laptop — and the footage you needed was never recorded. This is the checklist we run on maintenance visits across Dubai, adapted so your team can do the monthly basics themselves and know when to call a professional.
Monthly: the 15-minute health check
Once a month, someone on your team should open the live view and confirm every camera is actually showing video. It sounds obvious — and it is the single most commonly skipped step. While you're there:
- Confirm every camera is online: check the NVR channel list or your mobile app for "no video" or "offline" flags.
- Spot-check recordings: play back a minute from two or three cameras at different times of day to confirm the system is writing, not just displaying.
- Clean the lenses: in the UAE, dust from air conditioning and seasonal sand haze settles on lenses fast. A microfibre cloth is enough — never use harsh solvents.
- Verify date and time: footage with the wrong timestamp is useless as evidence. If the system isn't syncing to an NTP time server, set one up.
Quarterly: storage, firmware and the settings nobody revisits
Quarterly checks go deeper, into the parts of the system that degrade over time:
- Audit your retention: find the oldest playable footage and count the days. If your policy is 30 days but the drives only hold 21, your storage is undersized or configured wrong. Our guide on how long to keep CCTV footage explains how to size it.
- Check drive health: most NVRs report S.M.A.R.T. status for their hard drives. A drive showing warnings is a failure in progress — replace it before it dies.
- Update firmware: camera and NVR firmware patches close security vulnerabilities and fix bugs. Schedule updates outside business hours and confirm every device comes back online afterwards.
- Review motion and analytics zones: offices get rearranged, warehouse racking moves, seasons change the light. Zones that made sense in January may be triggering on a swaying banner in July.
- Test remote access: open the phone app and the web client as a normal user would. Logins that "worked when it was installed" have a habit of breaking after password changes and ISP swaps.
- Confirm night vision works: IR LEDs degrade over time, and a camera that looks fine at noon can be blind at midnight. Check the after-dark view at least once per quarter.
Twice a year: cabling, power and access
- Inspect outdoor equipment: UAE heat is hard on electronics and housings. Look for sun-faded seals, water ingress after rain (rare but destructive), corroded brackets and loose mountings.
- Test the UPS: if your recorder is on a UPS, run a battery self-test. A UPS with a dead battery gives you exactly zero minutes of runtime.
- Review user accounts: remove access for staff who have left and check who holds admin rights. Fewer admins means fewer accidental setting changes.
- Verify export works: copy a short clip to USB or download it, then play it on a different computer. The export function is what you reach for in an incident — discover it's broken before you need it.
Annually: the full system audit
Once a year, treat the system like a stranger. Walk the site against the original camera plan and look for new blind spots: new partitions, higher shelving, a relocated entrance, a camera whose field of view no longer answers the question it was bought for. Check the NVR for spare channel headroom, review whether your retention target still matches your policy, and review compliance — certain Dubai premises may have SIRA requirements — confirm applicability with your security consultant or the relevant authority before finalising any system design.
Know when to hand it to professionals
Monthly lens-cleaning and spot checks are fine in-house. Quarterly firmware, drive health and cabling work is where a technician earns their keep — one wrong firmware flash can brick a camera. This is exactly what an IT AMC covers: scheduled preventive visits where an engineer runs this whole checklist, documents the findings, and fixes small problems before they become incident-day failures.
