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.

Commission illumination as part of the camera system
Light quantity alone does not determine video performance. Distribution, spectrum, beam angle, distance, surfaces, exposure, and the required task must be tested together.

Prove infrared imagery on the real materials and distances
Infrared reflectance differs from visible appearance. Test clothing, plates, surfaces, weather, and target distances in the actual night mode before relying on the image.

Preserve scene metadata as a separately verified evidence track
Scene metadata can support search, alerts, and trends, but it has its own generation, transport, retention, and export path. Verify that path independently from video.

Make edge-storage encryption recoverable before enabling it
Encrypting a camera card can protect removed media, but initialization and recovery actions can erase recordings. Establish passphrase custody and recovery tests first.
