Full published values, conditions and source notes.
| Model-specific camera ceiling and licenses | Up to 44 IP cameras; 4 camera licenses included[1] Manufacturer camera-family lookup in the same archive.

| Included storage and optional costs | Diskless; HDDs/SSDs and backup storage purchased separately[2][1] Model-specific B&H new-enclosure listing; cameras beyond included licenses, optional network hardware and cloud storage can add costs. |

Software — Current limits (2026-09-11)
ADM 5.1, Docker family eligibility and series compatibility reread 2026-09-11.
| Current ADM branch | ADM 5.1 family. After installing ADM 5.1, Asustor says a downgrade to a previous version is no longer possible.[6] Policy page, not a hardware capability. Confirm the installed build on a retail unit. |
|---|---|
| Docker Engine family eligibility | Official Docker requirements explicitly include AS54. Container compatibility and practical capacity depend on image architecture, ADM/package release and installed RAM/CPU.[7] Family eligibility is not measured container capacity. |
| Drive compatibility policy | ASUSTOR publishes a series-level HDD/SSD list (including AS 12, AS 33 v2, AS 54, AS 67/AS 67 v2). Recertified drives are not recommended. Confirm the exact MPN on the live list.[8] |
