Planning estimate, not a quote. The written proposal after the walk is the number that matters. RAID is not a backup. On-prem UniFi Protect only. No cloud-camera seats. UniFi list prices and the chassis tariff move.
Recommended stack
3× UniFi 8 TB in a UNVR G2
You buy 3 drives. 2 store footage, 1 is protection (RAID 5). Usable 16 TB. One can die. Video stays. 1 bay left empty so we can add storage later.
This recorder does not power cameras. You'll need a PoE switch, and we spec a UPS.

What the UniFi store would ring up before tax, August 2026. Not a quote. Labor, tax, cameras, and cabling are on the written proposal. Surcharge is approximate. UniFi changes it.
Protection is shown as its own sled so the space cost is obvious. On RAID 5/6 the spare copy is striped across every drive.
All sleds spinning.

Other ways to build it
Planning estimate, not a quote. The written proposal after the walk is the number that matters. RAID is not a backup. On-prem UniFi Protect only. No cloud-camera seats. UniFi list prices and the chassis tariff move. UniFi US store: NVR chassis currently add ~7.8% as a tariff / import surcharge at checkout. Enterprise HDDs are sold at list, no extra line, but those prices move. Prices as of August 2026.
