Reolink CX810 Specs & Ownership Analysis

The CX810 prioritizes full-color low-light imaging rather than infrared-heavy night vision. It uses a 1/1.8-inch sensor, F1.0 aperture and 4K resolution.

Architecture difference

The reason to choose CX810 is not more resolution than other 4K Reolink models; it is the low-light optical design. For areas with ambient light where color evidence matters, that can be more useful than a generic IR specification.

The CX810 is a low-light design, not a zoom camera

Reolink documents a 1/1.8-inch sensor, F1.0 4mm lens and 3840×2160 video at up to 25fps. The optical system is the reason to choose it: the CX810 is designed for full-color low-light capture and has no infrared night-vision mode. Its warm 3000K spotlights can add illumination when the scene is too dark.

What that means in a real camera plan

The fixed 93.2° horizontal field of view is useful for a driveway, patio or storefront approach where the target zone is known before installation. It is not the right tool when you need to tighten framing after mounting. For that, a motorized model such as the RLC-811A or RLC-843A offers optical zoom.

Local-first architecture is the second major advantage

Reolink currently documents microSD storage up to 512GB plus RTSP, ONVIF and FTP, along with H.265/H.264 video. The camera is powered by 802.3af PoE or 12V DC. That combination supports several ownership paths: standalone microSD, Reolink NVR, NAS/third-party software where compatible, or a self-hosted recorder.

Storage planning

At 4K and up to 25fps, retention depends heavily on bitrate and whether you record continuously. If you plan 24/7 recording, size storage from the expected bitrate instead of assuming a fixed number of days from card capacity alone.
