The short version: these are not quite apples-to-apples, and that comparison is the point. The Reolink RLK8-800D4 is a complete 8-channel NVR system with four 4K cameras and 2TB of storage included in one box — buy it, wire it, done. The UniFi G5 Turret Ultra is a single premium camera that plugs into Ubiquiti’s separate UniFi Protect ecosystem, aimed at buyers who either already run UniFi networking gear or want to build a camera system piece by piece around it.
In Plain English
These two products look like competitors, but one is a whole system and the other is one piece of a system.
The Reolink RLK8-800D4 arrives as a complete kit: four sharp 4K cameras, a recorder box and a hard drive. You run a network cable from each camera to the recorder, and that one cable carries both power and video. The recorder then saves everything, all day and night, with no monthly fee.
The UniFi G5 Turret Ultra is a single camera. Owners rate it very highly, but it can’t record by itself. It needs a separate UniFi recorder or a UniFi router that runs Ubiquiti’s Protect software. That makes sense if your home or office already uses UniFi networking equipment, and it’s an extra purchase if it doesn’t.
Think of it like buying a boxed home cinema versus a premium speaker that plugs into a sound system you already own. The boxed kit works straight away. The premium speaker is excellent, but only once the rest of the system is in place.

Where the Real Differences Are
What’s actually included. The Reolink kit is genuinely all-in-one: four cameras, an 8-channel NVR and 2TB of storage in a single purchase. The UniFi G5 Turret Ultra is one camera — you separately need UniFi Protect-capable recording hardware to store and manage its footage, which is an additional cost and setup step if you are not already on a UniFi network.
Ecosystem lock-in. UniFi Protect is a polished, well-regarded platform, but it is Ubiquiti’s own ecosystem — worthwhile if you are already invested in UniFi networking, and a real barrier to entry if you are not. Reolink’s kit is self-contained and does not require buying into any wider ecosystem.
Rating. The UniFi camera edges ahead on average rating, though on a considerably smaller review base than Reolink’s.
Scale of purchase. Buying four Reolink-equivalent cameras plus an NVR and storage individually would typically cost more and take more research than the RLK8 kit’s single purchase; building an equivalent 8-camera UniFi system means buying eight G5 Turret Ultras plus NVR hardware separately, a considerably larger project and budget.
Video Quality and Resolution
The Reolink RLK8-800D4's four cameras shoot 8MP/4K with H.265 encoding. That keeps storage manageable across four channels recording around the clock. The UniFi G5 Turret Ultra is a single 2K camera — 4MP (2688 x 1512) on a 1/2.4-inch sensor, per Ubiquiti's spec sheet — so on raw resolution it actually sits below each of Reolink's 8MP cameras. Owner reviews consistently praise its image quality and low-light performance. Comparing the two on video quality alone somewhat misses the point. The Reolink kit optimizes for covering eight positions at a controlled cost per camera. The UniFi camera optimizes for the best single-camera image inside a network you already trust.
Night Vision
Both systems include night vision as standard. Infrared illumination does most of the work in full darkness on the Reolink dome cameras. The UniFi G5 Turret Ultra's night performance is one of the more consistently praised traits in its owner reviews, thanks to Ubiquiti's more premium sensor and processing pipeline. On paper the two are closely matched: Reolink rates the RLK8-800D4 cameras' infrared at up to 100 feet, and Ubiquiti rates the G5 Turret Ultra's at up to 98 feet (30 m). Check the current listing for whether color night vision is available, since that spec can shift between hardware revisions.
Connectivity, Storage and Recording
The Reolink RLK8-800D4 is genuinely self-contained. Four cameras, an 8-channel NVR and 2TB of storage arrive in one purchase, recording continuously with no subscription at any point. The UniFi G5 Turret Ultra needs separate UniFi Protect-capable hardware to record anything at all — either a dedicated UniFi NVR or a UniFi router/gateway with Protect support. That's a real additional purchase if you're not already on a UniFi network. Once that infrastructure exists, UniFi Protect is a well-regarded recording and management platform in its own right, and it scales cleanly as you add more UniFi cameras later.
App and Ecosystem
Reolink's app manages the whole kit — all four cameras and the NVR — from one interface. No separate account tier is required to unlock local recording. UniFi Protect is part of the wider Ubiquiti ecosystem. That's a genuine strength if you already run UniFi switches, access points or a UniFi gateway, since every device shows up in the same app and shares the same network intelligence. That same strength is a barrier if you have no other UniFi gear, because you're adopting an entire platform to run one camera.
Installation and Setup
The Reolink kit is a genuine cabling project. Four PoE cameras need Ethernet runs back to the NVR — a weekend job for most DIY installers, or a booked job for an electrician if the runs are long or go through brick. The UniFi G5 Turret Ultra is a single PoE camera, so its own installation is simpler in isolation. But building an equivalent 8-camera UniFi system means repeating that single-camera install eight times, plus configuring the separate NVR hardware — a considerably bigger project than the Reolink kit's one-box setup.
Price Tier and Total Cost
Check the current listing for both, since prices move. The shape of the cost comparison is durable, though. The Reolink RLK8-800D4 is a single purchase covering eight camera-ready channels, an NVR and 2TB of storage. Pricing a comparable 8-camera UniFi system means adding eight G5 Turret Ultras to whatever NVR or gateway hardware you need. That typically runs well past the Reolink kit's all-in price. The premium buys the UniFi ecosystem and its per-camera image quality, not just the camera itself.
Who Should Buy Which
Choose the Reolink RLK8-800D4 if you want a complete multi-camera system in one purchase with no separate ecosystem to research or buy into, and continuous local recording with no subscription. Choose the UniFi G5 Turret Ultra if you already run, or are actively planning, a UniFi network — the per-camera rating and image quality are genuinely stronger, but only worth the added cost and complexity if that networking investment already makes sense for your home or business.
Winner by Use Case
Best for a complete system in one purchase: Reolink RLK8-800D4, with everything included.
Best for buyers already on a UniFi network: UniFi G5 Turret Ultra, for tight integration with existing UniFi Protect infrastructure.
Best per-camera rating: UniFi G5 Turret Ultra, on the higher star average.
Best value for covering 8 positions without separate ecosystem research: Reolink RLK8-800D4.

Going Deeper: How PoE Powers Both Systems
Both products on this page rely on Power over Ethernet, and understanding it explains why neither needs an outlet at the camera and why the recorder you choose matters so much.
PoE is a published standard, not a brand feature. The IEEE 802.3af standard, board-approved in June 2003, added support for optionally powering 10BASE-T, 100BASE-TX and 1000BASE-T devices through the Ethernet connection. It defines how the power-sourcing equipment, such as an NVR or a PoE switch, detects a compatible device before sending it power. That detection step is why plugging a PoE camera into the right port is safe, and why the same cable can carry both power and video.
The Reolink kit builds the power supply into its recorder. Reolink’s RLK8-800D4 specifications list IEEE 802.3af/at compliance with a maximum of 25W per port. The same spec sheet says the NVR supports up to 12 IP cameras with a maximum of eight wired, records all cameras 24/7, and uses a single internal SATA bay (2TB included, up to 8TB per drive) plus an eSATA port. Each of the four included 4K dome cameras records at 3840 x 2160 with H.265 or H.264 compression and infrared out to 100 feet. Because the NVR supplies power directly, the kit needs no separate switch.
The UniFi camera is modest in its demands. Ubiquiti’s G5 Turret Ultra tech specs list PoE over a 10/100 Mbps Ethernet link, a maximum power draw of 4W, and a supported voltage range of 37 to 57V DC. They also list a 4MP 2688 x 1512 sensor, a 1/2.4-inch CMOS, infrared to 98 feet, an IP66 rating and people, vehicle and animal smart detections. Power is rarely the constraint with a camera like this. The real requirement, as covered above, is on the recording side.
In practice, that shapes the build. With Reolink, the recorder is the power source and the storage in one box. With UniFi, you are assembling PoE power, Protect recording and cameras as separate parts of a network, which is exactly why it suits people who already have that network in place.
Verdict
Choose the Reolink RLK8-800D4 if you want a complete, self-contained multi-camera system without building anything piece by piece. Choose the UniFi G5 Turret Ultra specifically if you are already on, or planning, a UniFi network — the per-camera quality and rating are strong, but only worth the added ecosystem cost and complexity if that infrastructure already makes sense for you.
