What you'll notice
The recorder restarts endlessly, freezes at the logo, or powers off at random.
Why it happens
Corrupted firmware after a power cut, a failing PSU, an overheating unit in a closed cabinet, or a shorted drive.
How we fix it
We isolate the failed element, re-flash or replace, and fix the environment — ventilation and a small UPS — so the next load-shedding cycle does not repeat the damage.
Still not working?
If the checks above haven't restored your nvr (network video recorder), this usually needs a technician. Our NVR Repairs service covers exactly this fault.
