Compatibility rows come directly from Synology's and QNAP's own published Surveillance Station / QVR Pro camera support lists - the same lists you'd find on their sites, made searchable. This site does not independently test camera-NAS pairings; it reflects what each vendor states it supports.
Synology doesn't publish a "still in production" flag for cameras, so this site uses the camera's required Device Pack version as a proxy: cameras requiring Device Pack 6.0+ are labeled "current," older ones "legacy." This is an approximation based on when Surveillance Station support was added, not a verified statement that a camera is currently manufactured or sold new.
Amazon and eBay prices come from live marketplace searches matched to each specific model by title and brand, not estimates. A few rules keep this data honest:
Pricing data is refreshed periodically, not in real time. If a price looks stale, the marketplace link itself always reflects live listings.
Fields like resolution, IP rating, PoE class, and IR distance are extracted from manufacturers' own published datasheets using automated text extraction. This process can occasionally misread a spec sheet's formatting; if something looks wrong, treat the manufacturer's own datasheet (usually linked from the product page) as the source of truth.
NAS model specs (bays, CPU, RAM, ports, capacity) are sourced from Synology's and QNAP's own product pages and datasheets, supplemented with the same automated extraction process used for camera features.
Data is refreshed on an ongoing basis, not a fixed daily schedule. If you spot an error - a wrong compatibility entry, a stale price, a misread spec - it's worth double-checking against the vendor's own published data (linked from each page) before relying on it for a purchase decision.
