UniFi Protect Camera Buying Guide: Cameras, Recorders & Storage

UniFi Protect is Ubiquiti's all-in-one video surveillance platform: cameras, a recorder and one app — with no per-camera license fees and no required cloud subscription. That integration is its biggest strength and the main reason buyers choose it, but it also means the smart way to shop is to plan the whole system, not just pick a camera. This guide covers the three decisions that matter: the recorder, the cameras, and storage & power.

How UniFi Protect works

Every UniFi Protect system has two parts: one or more cameras, and a console that runs the Protect application and records footage. Cameras connect over a single Ethernet cable that carries both data and power (PoE), and you manage everything — live view, recordings, motion and AI detections, users — from the UniFi Protect app on your phone or browser, with no monthly fee. Because the console decides how many cameras you can run and how much footage you can keep, choose the recorder first.

Step 1: Choose your recorder (console)

The console is the brain and the storage. Options, from small sites up:

• Entry / small sites: the UniFi Cloud Key Gen2 Plus is a compact Protect recorder with a built-in hard drive — ideal for a home or small office running a handful of cameras.
• All-in-one router + Protect: the Dream Machine SE and Dream Machine Pro combine your gateway, network controller and Protect NVR in one unit with a drive bay — the popular pick when you want networking and cameras on one box. The Dream Machine Pro Max adds more capacity and camera headroom.
• Dedicated / enterprise: the Enterprise NVR (ENVR) is a purpose-built, multi-bay recorder for larger camera counts and longer retention.

Rule of thumb: match the console to your camera count and how long you need to keep footage, and leave headroom — camera counts always grow. Browse recorders and cameras together under Cameras & Surveillance.

Step 2: Choose your cameras by use case

UniFi cameras share the same app and features, so pick by where they go and what you need to see.

• Compact / indoor & entry outdoor: the G5 Turret Ultra is a small, affordable turret for doorways, offices and tight spaces (also in black).
• General outdoor coverage: the G5 Bullet is the everyday outdoor workhorse for parking areas, entrances and yards.
• Higher-end outdoor & low light: the G6 Bullet brings the newer G6 sensor for more detail, better night performance and stronger on-device AI.
• Wide areas & specialty: UniFi also offers PTZ, multi-lens (AI Theta), doorbells and AI-focused models for large or specialized sites — see the full range in Cameras & Surveillance.

Tip: higher resolution captures more detail but uses more storage and bandwidth, so match resolution to the job rather than buying the biggest sensor everywhere.

Step 3: Size storage & power

Storage

Footage is kept on a drive inside the console. How long you can retain it depends on the number of cameras, their resolution and frame rate, and how much motion they see — more cameras or higher resolution means more storage for the same number of days. Use surveillance-rated hard drives built for continuous 24/7 writing, and if long retention matters, choose a console with a larger or expandable drive bay.

Power (PoE)

UniFi cameras are powered over Ethernet, so each needs a PoE source — either a Dream Machine/console with PoE ports or a separate PoE switch. Add up the cameras' power draw and make sure your switch's PoE budget covers it; our free PoE Budget Calculator does the math. Keep cable runs within 100 m (328 ft) per the Ethernet limit, and use outdoor-rated cable for exterior runs.

Does UniFi Protect work with third-party (ONVIF) cameras?

UniFi Protect is designed as an integrated ecosystem — UniFi cameras plus a UniFi console — and that is where it shines: no licensing, seamless updates, and unified AI and app. As of Protect 5.0, Ubiquiti added limited ONVIF support, so some third-party ONVIF cameras can be added and UniFi cameras can act as ONVIF sources — but support and features vary by model, so don't assume full parity with a native UniFi camera. If your project is specifically about mixing vendors or you need broad ONVIF interoperability, an open-ONVIF line such as Grandstream is the better fit; for a clean single-vendor system, stay all-UniFi.

Frequently asked questions

Do I need a subscription for UniFi Protect?

No. UniFi Protect has no per-camera license and no required cloud subscription — footage records locally to the console's drive, and remote viewing through your free UniFi account is included.

Which UniFi recorder do I need?

Match it to camera count and retention. A Cloud Key Gen2 Plus suits small sites; a Dream Machine SE, Pro or Pro Max is the popular all-in-one for homes and businesses; the Enterprise NVR handles larger camera counts and longer storage. Leave headroom for growth.

How much storage do I need for my cameras?

It depends on the number of cameras, their resolution and frame rate, and how much they record. More or higher-resolution cameras need more storage for the same number of days. Use surveillance-rated drives and pick a console with room to expand if long retention matters.

How are UniFi cameras powered?

Over PoE (Power over Ethernet) — one cable carries data and power. Power them from a Dream Machine/console with PoE ports or a dedicated PoE switch, and size the switch's PoE budget to the cameras with our PoE Budget Calculator.

Can UniFi Protect record third-party cameras?

Partially. Protect 5.0 added limited ONVIF support, so some third-party ONVIF cameras work, but features vary by model. For a fully integrated system use UniFi cameras; for broad multi-vendor interoperability, consider an ONVIF-focused brand such as Grandstream.
