REOLINK RLK16-800B8 Review

What sixteen channels actually buys over eight

The recorder ships with eight bullet cameras connected and eight channels open. That headroom is the entire reason to choose this kit over the RLK8-800B6: a detached garage, a second driveway camera, or a gate added a year later can be plugged straight into a spare channel rather than forcing a recorder swap.

REOLINK publishes a PoE cable run of up to 330 feet for this kit. That figure sits essentially at the 100 meter (about 328 foot) ANSI/TIA-568 Ethernet channel limit, so the extra two feet in the marketing figure reads as a rounding of the metric conversion rather than a genuine claim of exceeding the standard.

The storage math on the 4TB drive

At the typical 6 Mbps H.265 convention for an 8MP stream, one camera writes about 2,700 MB per hour. Across eight cameras recording continuously, that is 8 times 2,700 times 24, or 518,400 MB per day.

A 4TB drive holds about 3,720,000 MB of usable capacity once the standard 93 percent usable fraction is applied. Divided by the daily write, that is about 7.2 days of continuous 24/7 recording across all eight cameras. Motion-only recording extends this figure, though REOLINK does not publish a typical duty cycle to size the extension precisely, and a scene with a lot of night motion will write closer to the top of the typical bitrate range than the bottom.

What is not published for this listing

This listing does not state a focal length, an IR range in feet, or a low-light lux figure for the bundled cameras. Where the RLK8-800B6 listing does publish an IR distance for its cameras, this listing does not carry the same figure, and treating the two kits as identical on that point would be an assumption this review is not willing to make.

Anyone who wants an exact DORI identify distance for these cameras should pull the focal length from the printed manufacturer datasheet and run it through the DORI distance calculator, since a computed distance built on a guessed focal length is worse than no distance at all.

Price per camera against the RLK8-800B6

At $1,259.99 for eight cameras, this kit works out to about $157 per camera including the recorder and the drive. The RLK8-800B6 at $755.99 for six cameras works out to about $126 per camera, a meaningfully lower figure. The difference is the price of the eight spare channels and the larger 4TB drive, not the cameras themselves, so a buyer who genuinely needs sixteen channels should expect to pay a premium over a same-brand eight channel kit rather than assuming a larger box scales down in per-camera cost.

That premium is easiest to justify when the spare channels have a concrete plan behind them, a garage, a gate, a second building, rather than sitting empty as generic headroom. Empty channels do not depreciate, but they also do not pay for themselves.

Is this a hands-on review

No. This is not a hands-on review. This system has not been installed or run on a property by anyone on this team. The figures above come from the published listing and from the standard formulas this site documents, not from a mounted camera watched over time.

Who should not buy this

A four to six entry point house does not need sixteen channels, and the eight empty channels here are a cost with no return until they are filled. The RLK8-800B6, at six cameras on eight channels, is the better fit for that property size.

Anyone who has already decided on dome bodies for eave mounting should look at the RLK16-800D8 instead, which uses the identical recorder and drive specification in a dome housing that is harder to knock out of alignment.

A long single approach that needs to resolve a face at range, rather than eight separate detect-only positions, is better served by fewer cameras with real optical zoom, such as the RLC-823S1 PTZ, than by more fixed 4K bullets.
