Frigate vs Unifi Protect vs Synology NVR (UK 2026)

For UK smart-home users choosing a self-hosted NVR in 2026, three options dominate: Frigate (open-source HA add-on), Unifi Protect (Ubiquiti's polished ecosystem), and Synology Surveillance Station (running on a Synology NAS). Each suits a different starting point and budget; this comparison covers the practical trade-offs.

All three are credible self-hosted NVRs in 2026 but they target different users:

• Frigate is the developer-friendly open-source choice. Docker container or HA add-on; pairs with a Coral TPU (a £60 dedicated AI chip) for object detection that meaningfully outperforms most commercial NVR AI. Works with any RTSP/RTMP camera - mix-and-match Reolink, Amcrest, Hikvision, Dahua, anything ONVIF-compatible.
• Unifi Protect is the appliance-style commercial alternative. Buy a Cloud Key+, a Dream Machine, or a UNVR, plug in Unifi cameras, get a polished UI and mobile app. The trade-off is vendor lock-in: you can't add a £30 Reolink camera and expect it to work.
• Synology Surveillance Station sits on top of a Synology NAS. If you already own one for backups or media, surveillance is bolted on. Works with most ONVIF cameras; licences cost £50 per additional camera beyond the first 2 (which are free).

Worked example: 4 cameras, 4 weeks of continuous recording at 1080p, AI person/vehicle detection on 2 cameras.

• Frigate: Host PC £200-£400 (Mini PC or HA Green) + Coral TPU £60 + 4 cameras at £40-£80 each = £420-£780 total. Storage on the host PC; recording duration capped by drive size.
• Unifi Protect: Dream Machine SE £379 + 4 G4 Bullet cameras at £179 each = £1,095. AI features on the camera require G5-AI series (~£300/each), adding £450 for two of them.
• Synology Surveillance Station: DS923+ NAS £550 + 4 ONVIF cameras at £40-£80 each = £710-£870. First 2 camera licences free; additional 2 licences £100. For AI detection, upgrade to a DVA1622 (£700) or DVA3221 (£2000) instead.

For raw cost, Frigate wins. For polish per pound, Unifi Protect is the most consumer-ready. Synology is the best fit if a NAS is already in the cupboard.

AI object detection (person, vehicle, package, animal, etc.) is what separates a modern NVR from a glorified DVR:

• Frigate + Coral TPU: Hands down the best of the three. The £60 Coral TPU runs TensorFlow object detection at near-zero CPU cost and produces detections with very low false positive rates. Detected objects appear as HA entities for automation.
• Unifi Protect AI cameras (G5-AI, AI-Theta): Strong detection done on-camera. Person and vehicle detection are reliable; package detection is decent. The premium camera price is the cost.
• Synology Surveillance Station: No AI on standard DSM NAS. The DVA-series adds it but at £800-£2000 the NAS price is the gate.

For typical UK home smart-home users wanting AI without enterprise budgets, Frigate is the only credible answer under £150 total for the AI hardware.

HA integration quality drives most smart-home users' choice here:

• Frigate: Native HACS integration, official Frigate cards in Lovelace, motion events flow into HA as triggers. The best HA integration of any NVR by a meaningful margin.
• Unifi Protect: Community uiprotect integration is mature and reliable, but it's not an official Ubiquiti product. Cameras and motion events expose in HA cleanly; live stream playback works.
• Synology Surveillance Station: The synology_dsm community integration is more focused on the NAS itself than Surveillance Station. Camera streams and basic events expose; richer triggers require manual MQTT plumbing.

For UK smart-home users in 2026, the choice usually splits along existing-hardware lines. If you're running Home Assistant on a Mini PC or HA Green/Yellow, Frigate is the lowest-cost and tightest-integrated option, and the Coral TPU gives you AI detection that the commercial alternatives charge premium prices for. If you already run Unifi networking, Unifi Protect is the polish-per-pound winner. If you already run a Synology NAS, Synology Surveillance Station bolts on without new hardware, though the AI gap is real unless you go DVA.

For complete green-field installs choosing fresh from scratch, the order most HA-aware users settle on is Frigate first, Unifi Protect second, Synology Surveillance Station third - based on AI quality and HA integration. For families wanting a consumer-friendly UI without HA, the order flips: Unifi Protect first, Frigate second (only if you're comfortable maintaining it), Synology third.
