The camera and NAS databases answer "is this compatible" and "what does it cost." These guides cover the questions that come before and after that: which platform to buy into, how many licenses you need, how to plan storage, and what to check before buying used gear. Independently written -- see Methodology for how the underlying data is sourced.
Buying assessment on the model page: what Surveillance Station supports, which revision and Device Pack the evidence covers, what is still unverified. Also: RLC-510A (budget PoE) and Duo 2 PoE (wide coverage).
The 2.5GbE-vs-10GbE trade-off, who each suits, what filling the bays costs today, and the drive, memory and expansion constraints - above the spec table on the model page. Plus the QNAP TS-464 vs TS-473A.
Compare exact models, recent listing evidence and explained value scores in a regularly rebuilt shortlist.
The same shortlist for QNAP's QVR Pro compatibility list: exact models, recent prices and a short take on each.
What a Device Pack actually is, why it's the basis for this site's "current" vs. "legacy" split, and how to check what version your own NAS is running.
Surveillance Station and QVR Pro both charge per camera channel past a free allotment. How to count what you actually need, with room to grow.
Choosing between Synology and QNAP as a surveillance platform -- licensing, compatibility model, and catalog differences, not a verdict on which is "better."
A walkthrough of the filters, sections, and badges on the camera databases -- including what "Verified" on Amazon actually means.
The tradeoffs that matter for a NAS-based install specifically: cabling, power, reliability, and the PoE switch you'll probably also need to budget for.
The math behind the bandwidth & storage calculator on this site, and how to think about continuous vs. motion-triggered retention.
What "legacy" means here (not "broken"), and a practical checklist for buying used surveillance gear on eBay.
