What you'll notice
The NVR runs, but admin access is locked and nobody holds the credentials.
Why it happens
Unrecorded installer passwords, staff changes, or defaults changed and forgotten.
How we fix it
Official manufacturer reset with proof of ownership, then a proper credential handover — including the camera passwords, which are frequently different from the recorder's.
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.
