Reolink CX820 4K PoE Dome Camera

The Reolink CX820 is a single 8MP dome network camera built for outdoor surveillance. It delivers 4K resolution at 3840*2160 with HDR technology for balanced shadows and highlights. Power over Ethernet simplifies installation with a single RJ45 cable carrying both data and power. Smart detection identifies people, vehicles and animals to reduce false alerts.

IP67 Weatherproof Thermals and Power

The IP67-rated housing protects the camera from dust and rain across challenging outdoor conditions. PoE power delivery eliminates separate power adapters and reduces cable runs. The F1.0 super aperture and 1/1.8" sensor gather four times more light than F2.0 lenses for brighter images day and night. ColorX night vision provides full-colour footage in low light without extra illumination.

3000K Spotlights and Local Storage

Integrated 3000K spotlights activate with motion detection alongside a siren for sound-light deterrence. Two-way audio allows remote communication to warn off intruders. A micro SD slot accepts cards up to 256GB for onboard recording. The camera also supports NVR and FTP storage options. ONVIF compliance enables integration with compatible third-party systems.

Questions about this item

How do I install the Reolink CX820 dome camera on a wall or ceiling and which step is most often missed?

Mount the base to the wall or ceiling, run a single Ethernet cable to a PoE switch or injector, then secure the dome; the step most often missed is verifying the PoE source delivers enough power before final tightening.

What maintenance will the Reolink CX820 need over time?

Clean the dome cover periodically to keep the F1.0 aperture clear, check the Micro SD card health if recording locally up to 256GB, and apply firmware updates when released.

What limit appears first during continuous 4K recording on the Reolink CX820?

The Micro SD card capacity tops out at 256GB, so sustained 3840×2160 capture will fill the card before any other hardware limit is reached.
