REOLINK RLK8-800B6 Review

What is actually included in the box

The kit ships as one 8 channel NVR, six 4K (3840x2160) bullet cameras with on-device person, vehicle and animal detection, and a 2TB hard drive already installed inside the recorder. REOLINK publishes a PoE cable run of up to 300 feet per camera, which sits comfortably inside the 100 meter (about 328 foot) ANSI/TIA-568 Ethernet channel limit, so the stated figure does not require anything unusual to hit.

Two of the recorder eight channels ship empty. That is a real feature, not a shortfall: it means a seventh and eighth REOLINK PoE camera, such as the RLC-810A reviewed separately on this site, can be added later without buying a new recorder.

How long does the pre-installed 2TB drive actually last

REOLINK typical sustained bitrate convention for an 8MP H.265 stream is about 6 Mbps, which converts to storage at 6 Mbps times 450, or roughly 2,700 MB per camera per hour. Across six cameras recording continuously, that is 6 times 2,700 times 24, or about 388,800 MB written every day.

Usable drive capacity runs at roughly 93 percent of the marketed figure once the recorder database and overwrite headroom are accounted for, so a 2TB drive offers about 1,860,000 MB of usable space. Divide that by the daily write and the result is about 4.8 days of continuous 24/7 recording across all six cameras. That number is a convention-based estimate, not a guarantee: REOLINK does not publish a fixed bitrate, and a hedge moving in wind at night can push real bitrate well past the typical figure used here.

In practice, most owners set the recorder to record on motion rather than continuously, which stretches that runway considerably, though REOLINK does not publish a typical motion duty cycle to plug into the same formula. Anyone planning to record continuously on all six channels should budget for the external drive expansion the features list mentions, up to 16TB across two additional drives.

What REOLINK does, and does not, publish about night vision

The listing states the infrared LEDs on these cameras reach up to 100 feet. That is a manufacturer figure measured under ideal conditions against a reflective target, and it is the only night vision distance published for this exact bundle. There is no published low-light lux rating and no published real-world working distance in typical conditions, so neither should be treated as known for this product.

The listing also does not publish a focal length for the bundled cameras, which means an exact DORI (detect, observe, recognise, identify) distance cannot be computed for this specific kit the way it can for a camera that does publish one, such as the standalone REOLINK RLC-810A reviewed separately, which lists a 4mm lens. Anyone who wants the actual DORI numbers for this kit should pull the focal length from the printed manufacturer datasheet that ships in the box, then run it through the DORI distance calculator.

Is this a hands-on review

No. This is not a hands-on review. Nobody on this team has installed the RLK8-800B6 on a real property, and there is no lab result or multi-week trial behind any figure above. Every number in this review is either quoted directly from the REOLINK listing or computed from those published figures using the standard DORI, storage and PoE formulas documented on this site.

Who should not buy this

A house with only four true entry points is paying for two cameras and two recorder channels it may never use; the four camera REOLINK RLK8-410B4-5MP kit covers that case at a lower price per camera.

A driveway or approach longer than the distance a fixed 4K bullet camera can actually identify a face at is not solved by adding more of these cameras. That calls for an optical zoom camera such as the RLC-823S1 or RLC-811A, since digital zoom on a fixed lens adds no real pixels to the scene.

Anyone who wants a stated low-light lux figure or a true DORI identify distance before buying will not find either published for this kit, and should look at a listing that states a lens focal length instead.
