Record panoramic video investigators can dewarp later
Panoramic cameras can deliver different views and dewarping options. Confirm that the archive preserves the view investigators need, not only a convenient live layout.

Accept focus across the required depth, not at one target point
A sharp test chart at one distance can hide unusable foreground or background detail. Commission lens choice and focus across the full operational zone.

Tune image-health alerts with human validation
Image-health analytics can flag blocked, redirected, blurred, or underexposed views, but they cannot determine operational intent. Validate alerts against each scene and workflow.

Use RTCP loss and jitter as transport evidence, not image proof
RTP control reports can expose packet loss and interarrival jitter. They help diagnose delivery but do not prove that recorded video is complete or usable for the intended task.

Treat SRTP as stream protection, not complete VMS security
SRTP can protect RTP and RTCP media traffic, but its result depends on key management and does not secure camera administration, storage, export, or operator access.

Test RTSP session survival across firewalls and idle periods
RTSP is stateful and includes session timeout behavior. Verify keepalives, transport choices, recovery, and version support through the exact production path.

Size edge storage from write workload and recovery needs
Retention capacity is only one edge-storage requirement. Sustained writes, media endurance, outage duration, and copy-back time determine whether the design can recover.

Accept intelligent compression with incident scenes, not average savings
Content-aware compression can reduce bandwidth and storage, but averages do not prove that fast or complex incident detail survives. Test the tasks that matter.

Ground the complete camera path before claiming surge protection
A surge protector is only one part of a camera installation. Cable routing, shielding, grounding, PoE equipment, and building practices determine the real protection path.

Test cold startup separately from normal camera operation
A camera may have different operating and startup temperature limits. A device that continues running in cold weather may not restart after a power event at the same temperature.
