The Reolink B800 is a 4K 8MP PoE bullet camera built for continuous, wired outdoor or indoor coverage rather than battery operation. Reolink has since positioned the RLC-810A as its direct successor, but the B800 remains a capable option if you already own one or find it at a good price. Here’s what it offers and how to set it up.
Key Specs
- 4K (8MP) resolution at 3840×2160
- 87° horizontal field of view, 47° vertical
- 18 infrared LEDs with 3D-DNR noise reduction for night footage
- IP66 weatherproof rating, suitable for both indoor and outdoor mounting
- Powered via PoE, with a single Ethernet cable carrying both power and data up to roughly 330 feet
Setting Up the B800
- Connect the camera to a PoE NVR or PoE injector using a standard Ethernet cable
- Add the camera in the Reolink app, either automatically if connected to a Reolink NVR or manually via its IP address
- Mount at your chosen height and angle, then confirm the field of view covers your intended area
- Adjust detection settings and recording schedule to match your needs
Since the B800 is officially discontinued in favor of the RLC-810A, it’s worth checking Reolink’s current compatibility lists before buying additional B800 units to expand an existing system — newer NVR firmware is tested primarily against current models, and older discontinued cameras occasionally see reduced testing priority over time.
Is It Worth Buying Now?
If you’re expanding an existing system that already uses B800 units, adding more for consistency makes sense. For a brand-new purchase, the RLC-810A is the more future-proof choice since it’s Reolink’s actively supported current model in the same product tier.
For full specifications, see the official B800 IP Camera Specifications sheet, and Reolink’s B800/D800 support section.
Frequently Asked Questions
Is the B800 still supported with firmware updates?
Discontinued models typically still receive occasional updates for a period, but check Reolink’s support section for the latest status on your specific unit.
Can the B800 work without an NVR?
Yes, it can connect to a PoE injector and be added directly to the Reolink app without requiring a full NVR system.
Does the B800 support audio recording?
Yes, it includes a built-in microphone for audio alongside video recording.
What’s the practical difference between the B800 and RLC-810A?
They’re closely related in specs, with the RLC-810A being the actively sold and supported successor model in Reolink’s current lineup.
Conclusion
The B800 remains a solid 4K PoE camera if you already own one or are expanding a matching system, though new buyers are generally better served by its current successor, the RLC-810A. Either way, the PoE-based wired approach means one cable handles both power and data, keeping installation simple.
