Here is a number most enterprise security managers have never calculated: what percentage of your cameras are actually online right now?

Not theoretically online. Actually streaming, unobstructed, with working storage, correct timestamp, and no signal degradation.
For most multi-site operations the honest answer is: unknown.
Camera health monitoring exists to answer that question continuously, automatically, without anyone manually checking.
What a camera health monitoring system tracks:
Device uptime — is the camera online and streaming
Signal quality — is the feed clear or degraded
Storage status — is the NVR recording correctly
Tamper detection — has the camera been moved or covered
Timestamp sync — is the footage timestamped accurately for legal validity
Why this matters beyond security:
For retail chains, a camera down in a high-value zone means a gap in shrinkage coverage. For logistics hubs, a blind dock bay is a theft liability. For banks, a non-functioning ATM camera is a regulatory compliance failure.

Agrex AI's AIVIS platform currently monitors 150,000+ cameras across 10,000+ facilities in India. The security camera system health monitoring module sits as a live dashboard — every device, every site, every alert in one view.
The industry benchmark for camera uptime SLA in enterprise deployments is 99.5%. Most operations without active monitoring are running at 88–92% without knowing it.
That 7–10% gap is where incidents happen.
