For a 20-to-60 camera luxury estate, the recorder choice usually comes down to two Ubiquiti tiers: the Network Video Recorder Pro, rated for up to 24 4K cameras, or a step up into the Enterprise NVR line once the camera count or retention target grows. RAID protection is built into every tier, but how much usable storage survives RAID overhead depends on drive count, resolution, codec, and whether cameras record continuously or only on motion. Getting this right before cabling closes avoids a mid-project recorder swap.
How many cameras does each NVR tier actually support?
Ubiquiti's current lineup scales in clear steps. The Network Video Recorder Pro is "a 2U-sized video recorder with (7) 2.5/3.5" HDD bays that can provide up to 60 days of storage for (24) 4K cameras or (70) Full HD cameras," according to Network Video Recorder Pro - Ubiquiti Store United States. That puts the mid-tier NVR Pro at the low end of a 20-60 camera estate — comfortable for 24 cameras at 4K, but already at its rated ceiling before accounting for growth.
Above the NVR Pro sit the Network Video Recorder G2 Pro and the Enterprise NVR. Ubiquiti's product catalog describes the G2 Pro as a "2U UniFi Protect NVR with built-in AI event analytics, HDMI output, eight 2.5"/3.5" HDD bays, and support for up to (50) 4K or (100) Full HD cameras," while the Enterprise NVR is a "3U NVR with (16) 2.5/3.5" drive bays, supporting up to (70) 4K cameras or (210) Full HD cameras," per Ubiquiti Store United States. For an estate landing in the middle of the 20-60 camera range — say, 30 to 45 4K cameras across a main house, outbuildings, and perimeter — the G2 Pro or Enterprise NVR gives headroom that the entry-level NVR Pro does not. An estate expecting to stay near 20-24 cameras long-term can reasonably spec the NVR Pro; one planning toward 40+ should design around the larger bay count from the start rather than migrating hardware later.
If the property is likely to grow well past 60 cameras over time — a compound with multiple structures, or a main house plus a guest house and gatehouse each getting full coverage — the Enterprise NVR Core is the recorder built for that scale, supporting "up to (300) 4K or (500) Full HD cameras" with "hot-swappable power supplies" and RAID protection, per the same Ubiquiti catalog listing. That's almost certainly more recorder than a 20-60 camera estate needs today, but it's worth knowing where the ceiling sits before committing to a smaller chassis that can't be expanded.
What does RAID protection actually buy you on these recorders?
Every tier in Ubiquiti's current NVR lineup — from the entry NVR through the NVR Pro, G2 Pro, Enterprise NVR, and Enterprise NVR Core — is listed with "RAID Protection" as a standard feature, per Ubiquiti Store United States. RAID spreads footage across multiple drives so that a single drive failure doesn't take down the recording history for the whole estate. That matters more as camera count rises: a 40-camera estate recording continuously generates enough data that a drive failure without redundancy could mean losing days or weeks of footage at the worst possible moment. RAID overhead also means the usable storage is always less than the sum of the installed drives' raw capacity — a detail that should be worked out with your installer before drive capacity is ordered, since the math changes depending on which RAID level the recorder uses and how many bays are populated.
Ask your contractor to walk through the exact RAID configuration proposed for your recorder and what usable capacity — not raw drive capacity — that configuration actually delivers for your target retention window.
How does retention target change the recorder you need?
Retention — how many days of footage stay on the recorder before older clips are overwritten — is driven by drive capacity, not just bay count. Ubiquiti's own listing for the NVR Pro ties its 60-day retention figure specifically to 24 4K cameras, which illustrates how closely retention and camera count are linked on a given chassis: add more cameras, or raise resolution, and the same drives cover fewer days. A central station or insurer may expect a specific retention window to be documented as part of a monitored security program; that expectation should be set before drive capacity is finalized, not discovered afterward. For context on how alarm monitoring and documented retention windows fit into a broader program, see Cave Group's security upgrade page.
Resolution and codec also move the math. A camera recording in 4K continuously consumes dramatically more storage over a retention window than the same camera recording FHD or only on motion-triggered events — which is why Ubiquiti lists a materially higher Full-HD camera count against the same recorder hardware than its 4K figure, across every tier in the lineup. An estate that wants true 4K continuous recording on every camera needs a larger recorder, more drive bays, or a shorter retention window than one that mixes continuous recording on key entry points with motion-based recording elsewhere.
What should be decided before a recorder is ordered?
Before committing to a chassis, an estate's design team should settle: the camera count expected at full build-out (not just phase one), whether entry points and perimeter cameras need continuous 4K recording versus motion-triggered recording for interior or low-traffic zones, the retention window required by any insurer or monitoring agreement, and how much headroom to build in for cameras added later. These decisions determine whether a 7-bay NVR Pro, an 8-bay G2 Pro, or a 16-bay Enterprise NVR is the right starting chassis — and getting it wrong means either an undersized recorder that runs out of bays, or an oversized one that adds unnecessary rack space and power draw. Cave Group designs camera coverage and recorder sizing together as part of its complete security stack, pairing UniFi Protect cameras and recorders with access control and monitored alarm layers rather than treating storage sizing as an afterthought.

Frequently asked questions
How many cameras can a UniFi NVR Pro actually support?
The NVR Pro is rated for up to 24 4K cameras or 70 Full HD cameras across its seven drive bays, with up to 60 days of storage at the 24-camera 4K figure, according to Ubiquiti's product listing.
Is RAID included on every UniFi NVR tier?
Yes. Ubiquiti lists RAID Protection as a standard feature across its current NVR lineup, from the entry-level NVR through the NVR Pro, G2 Pro, Enterprise NVR, and Enterprise NVR Core.
When does an estate need the Enterprise NVR instead of the NVR Pro or G2 Pro?
The Enterprise NVR supports up to 70 4K cameras across 16 drive bays, well beyond the NVR Pro's 24-camera rating, making it the right choice once an estate's expected camera count moves toward the upper end of a 20-60 camera range or beyond.
Does camera resolution change how much retention a recorder delivers?
Yes. The same recorder hardware supports a much higher Full HD camera count than its 4K figure, which means recording in 4K continuously on every camera shortens the retention window compared to mixing resolutions or using motion-triggered recording on lower-priority cameras.
Who should set the retention window for a monitored estate?
The retention window should be agreed between the property owner, the installer, and any insurer or central-station monitoring provider before drive capacity is finalized, since central stations and some insurance policies expect a documented minimum retention period.
