CCTV maintenance: catch it before the day you need the footage
A CCTV system rarely breaks in a way you notice. It degrades. A disk starts failing, a camera drops out at night, the retention quietly shrinks from thirty days to eleven. You find out the day you need the footage. Maintenance is there to find out before that day.
Short answer
What does CCTV maintenance involve?
Checking that every camera records what it should, that the disks are healthy and the retention is what you were promised, that firmware and software are up to date, and that only the right people still have access. Plus testing that failover actually works, rather than discovering it doesn’t during an outage.
Checklist
What should a CCTV maintenance checklist include?
- Every camera records. Not just live view: is there actually footage for the last days, at the expected quality?
- Real retention. How many days are on disk now, compared with what was agreed. Cameras added later often eat into it.
- Disk health. Warnings, errors and age. A disk that starts failing gets replaced before it takes footage with it.
- Firmware and software. Cameras, servers and the video management software up to date, with known security issues fixed.
- View and image. Lenses clean, nothing grown or built in front of a camera, night images still usable.
- Access. Who still has an account, and who should no longer have one.
- Failover and alerts. Does recording move when a server or disk fails, and does the alert actually arrive?
Frequency
How often should CCTV be serviced?
For most business systems, a full check once a year, with remote health monitoring in between, so a failing disk or an offline camera is noticed within days rather than months. Larger or critical systems benefit from a quarterly check. What matters more than the interval is that alerts are set up and someone acts on them.
Updates
Why are updates part of maintenance?
Because an update sometimes changes more than the version number. Since Nx Witness 6.1, for example, devices without a licence get a live-view interruption every ten minutes, see Live Streaming Time Limit Reached. We count channels and check licences before every update, test it first and roll it out in stages, so your reception doesn’t find out the hard way.
Who we are
Who maintains your Nx Witness system?
For Nx Witness, technical support runs through the authorised reseller, and that is us. We maintain systems we installed and systems we took over, including ones where the original installer can no longer be reached. Licences and servers we supply across Europe, maintenance and monitoring we do remotely, and on-site work in the Netherlands and the immediate border region.

Questions about CCTV maintenance
Can maintenance be done remotely?
Most of it. Health checks, firmware, software updates and access reviews can be done remotely. Cleaning lenses and replacing hardware needs someone on site.
Do you maintain systems you didn’t install?
Yes. We take over existing Nx Witness systems and other systems, and first check what is installed and that the system is yours.
What does a maintenance report include?
Which cameras record and at what quality, the real retention, disk health, versions, who has access, and what we recommend fixing. Useful as evidence for an audit too.
When was your system last checked?
We check every camera, disk, version and account, and tell you what needs attention. Also for systems we didn’t install.
