Bottom line: a configuration that says 30 days does not prove that footage from 30 days ago exists. The defensible measure is the earliest recording that authorized users can locate and retrieve for each required stream.

\n

Source fact: low free space can override a day target

\n

The AXIS Camera Station Pro User Manual — Select storage devices to connect documents retention settings and displays information about the oldest recording. It also explains that when the storage space reserved for AXIS Camera Station Pro becomes full, the system can delete old recordings even when they have not reached the configured retention age.

\n

This is expected capacity management, not necessarily a software failure. Variable scene complexity, added cameras, changed frame rates, event volume, evidence locks, other files, or a storage fault can consume the reserve that made the original calculation work.

\n

Source boundary and applicability

\n

The manual applies to AXIS Camera Station Pro and does not define an organization’s required retention. Editions, versions, storage topology, archive configuration, and camera-specific policies affect behavior. A displayed oldest timestamp also does not by itself prove that every interval between that point and now is continuous and playable.

\n

Applicability questions

\n\n

DSE recommendation: make oldest retrievable footage a service indicator

\n

The following steps are DSE recommendations based on the cited source.

\n

Record the approved minimum for each camera class and compare it on a defined cadence with the actual oldest searchable recording. Add a warning margin long enough for investigation and capacity remediation. Trend used and free capacity, write rate, camera count, profile changes, recording gaps, storage health, and locked evidence so the cause can be distinguished.

\n

Periodically retrieve clips at the oldest boundary, a midpoint, and a recent timestamp through the normal investigator account. If actual history is short, preserve active evidence, identify the constraint, and use approved changes to capacity, recording profile, or retention priority. Do not silently lower the requirement to match current storage.

\n

Verification and evidence

\n

Retain the approved retention matrix, configuration export, oldest-recording samples by camera, retrieved clips, capacity and bitrate trends, deletion or storage events, alert test, investigation tickets, and remediation approval. Repeat after adding devices or changing resolution, frame rate, compression, archive, or evidence-lock behavior.
