UniFi Network Video Recorder G2 Pro

The Ubiquiti UNVR-G2-Pro is a 2U rack-mount UniFi Protect network video recorder built for large-scale surveillance. Eight 2.5"/3.5" drive bays, a 10G SFP+ uplink and an eight-core Qualcomm Kryo processor let it record and analyse up to 100 Full HD, 70 2K or 50 4K cameras — with AI event analytics running on the appliance itself, no per-camera licence fees, and no cloud subscription.

Key features

• Up to 50 x 4K cameras — or 70 x 2K, or 100 x Full HD on a single appliance.
• Eight 2.5"/3.5" drive bays — HDD or SSD, with RAID data protection.
• Built-in AI event analytics — smart detections and search processed on-device.
• 10G SFP+ + 2.5 GbE RJ45 — headroom for dozens of high-bitrate streams.
• HDMI output — drive a wall display directly, no separate viewing PC.
• Runs Protect, Access and Connect — video, doors and displays on one console.
• Redundant power ready — USP-RPS DC input alongside the internal 200 W PSU.
• NDAA compliant — approved for government, education and defence-adjacent projects.
• 2U rack-mount, SGCC steel chassis — 442.4 x 87.4 x 325 mm, 8.4 kg.

Record and analyse up to 50 4K cameras on one appliance

The UNVR-G2-Pro is the highest-capacity recorder in the UniFi Protect NVR range. It manages 100 HD, 70 2K or 50 4K cameras, which makes it a fit for a full site rather than a single building — warehouses, schools, multi-storey offices, retail chains, car parks and logistics yards.

Because capacity scales by resolution rather than by licence tier, you can mix G5, G6 and AI-series cameras across the same recorder and rebalance later without buying anything extra. Every camera you add is a camera you own outright.

On-device AI event analytics — no cloud, no subscription

An eight-core Qualcomm Kryo CPU built on 4 nm Arm Cortex technology (one 3.2 GHz prime core, four 2.8 GHz performance cores, three 2.0 GHz efficiency cores) with 16 GB of memory does the analytics work locally. That means person, vehicle and animal detection, licence plate reading and smart search run inside your network, on your hardware.

Practically, this matters in three ways: footage never leaves the site unless you send it, there is no recurring analytics bill, and detection keeps working when the internet link drops.

Eight drive bays with RAID data protection

Eight 2.5" or 3.5" bays accept standard SATA HDDs or SSDs, with a 155 W drive power budget so you can populate all eight with full-size surveillance drives. RAID-based redundancy protects the array against a single drive failure — a genuine requirement when footage is evidence and retention is a compliance obligation.

Drives are not included. Pair the UNVR-G2-Pro with surveillance-rated drives such as WD Purple or Seagate SkyHawk, which are built for the continuous write cycles that CCTV produces. Desktop drives will work, but they will not last.

Sizing rule of thumb: multiply your camera count by your average bitrate by your retention days.

10G SFP+ networking so the uplink is never the bottleneck

The recorder pairs a 10G SFP+ port with a 2.5 GbE RJ45 port. On a 50-camera 4K deployment, gigabit uplinks are the usual failure point — streams stutter, playback scrubs badly, and exports crawl. A 10G fibre or DAC link into your aggregation switch removes that constraint entirely.

HDMI viewport for live wall displays

An integrated HDMI output drives a monitor or video wall directly from the recorder, showing up to 16 simultaneous 4K viewport streams. Reception desks, security offices and control rooms get a live view without a dedicated viewing workstation or a separate Protect Viewport device.

One console for video, door access and displays

The UNVR-G2-Pro is a UniFi OS console, not a single-purpose recorder. Alongside UniFi Protect, it runs UniFi Access as a controller for 150+ access hubs, and supports UniFi Connect for digital signage and room displays.

For an integrator, that is one appliance, one interface and one support surface instead of three. Door-forced-open events sit in the same timeline as the camera footage that captured them.

Software requirements: UniFi Protect 7.1.55 or later; UniFi Access 4.2.16 or later.

Built for continuous duty

• 200 W internal AC/DC PSU with universal 100–240 V AC input (3 A max, 50/60 Hz).
• USP-RPS 11.5 V DC input for redundant power — a second supply path if the primary fails.
• SGCC steel enclosure and rack ears.
• Status LEDs for Ethernet, SFP+, RPS, each HDD and system state.
• 0–40 °C operating range, 5–95% non-condensing humidity.
• Certified CE, FCC, IC and NDAA compliant.
