Unifi Protect Cameras: A Beginner's Buyer's Guide (UK 2026)

Three structural differences shape every buying decision here.

Local storage by default. Footage records to a network video recorder (NVR) in your house - a UNVR, a Cloud Key Gen2 Plus, or a Dream Machine, the Unifi all-in-one router that integrates security gateway and network controller, with a hard drive. There's no cloud subscription, and the cameras refuse to phone home with your video. You can opt in to remote viewing through the Unifi mobile app, which routes through Ubiquiti's relay service, but the footage stays local. For people who want home security cameras without sending video clips to a third party indefinitely, this is the whole point.

Power over Ethernet (PoE) is the default. Most Unifi cameras run on a single network cable that carries both data and power. You'll need a PoE switch (Unifi makes several, but any 802.3af or 802.3at PoE switch works) or a Dream Machine with built-in PoE ports. There are a couple of wireless/battery models for cases where running a cable is impossible, but the system is structurally wire-first.

The hardware costs more upfront, but the spend stops. A reasonable 4-camera setup with NVR runs £600-£1,000 depending on the cameras you pick. Compare that against £200-300 for a starter Ring kit plus £100-150/year for Ring Protect Plus. Break-even is usually 2-3 years, after which Unifi is purely cheaper. Our Unifi starter kit guide covers the cost breakdown in detail.

Four questions narrow the lineup down quickly:

Ubiquiti has been rolling out the G5 generation for a couple of years now, but G4 models are still on shelves at lower prices and they remain perfectly functional. The headline differences are sensor quality (G5 handles low light noticeably better), form factor (G5 has more compact options), and ongoing firmware support (G5 will outlive G4 by several years).

Every Unifi Protect setup needs a place to store the recordings. Three viable options:

For storage sizing, the rule of thumb: 1TB stores about 10-14 days of continuous recording from one 4MP camera at sensible settings. If you record on motion only rather than continuously, you can multiply that by 5-10x. Most home setups land on 2TB-4TB of storage for 4 cameras and never run out.

The marketing pages around Unifi Protect's AI features are intentionally vague. Here's the actual breakdown:

If you only need person/vehicle/animal alerts (which covers 80% of what home users actually want), the standard G5 Bullet at £170 is fine - you don't need the £640 AI Pro. The premium AI features are useful for specific use cases (driveway with regular deliveries, gate monitoring with car identification) and decorative for most others.

Three points to be explicit about:

Footage stays local by default. Cameras stream to your NVR via the LAN; the NVR holds the footage. Ubiquiti's cloud service doesn't see your video. If you enable remote viewing in the Unifi app, the connection goes through Ubiquiti's relay servers but the relay is end-to-end encrypted and they don't keep the content.

The app needs an account. You'll create a Ubiquiti SSO account during setup. The account is used to authorise the mobile app against your NVR. Use a unique password and enable 2FA - these accounts have been hit by credential-stuffing attacks (so has every smart-home vendor), and the consequence of a compromised Ubiquiti account is access to your camera feeds.

Face recognition opt-in matters. If you turn on face recognition you're storing facial fingerprints (locally). That's fine for many households but worth being deliberate about, especially if children or live-in carers are in scope. There's no requirement to use the feature; it's off by default.

Worked example for a typical UK semi-detached house:

Total: roughly £1,490 one-time. Compare against a Ring kit at £250 + Ring Protect Plus at £100/year = £550 over 3 years, £850 over 6 years. Unifi crosses over at year 6 in pure cash terms - but you also get materially better cameras (G5 sensors beat Ring's at low light), local storage, and no vendor-lock-in. The Ring kit isn't wrong for many households; the cost story just isn't as one-sided as it looks at first glance.
