The Reolink CX820 is a premium dome PoE IP security camera optimized for reliable outdoor monitoring, providing 4K UHD resolution with HDR for vivid, detailed footage across varying light conditions.

Its ColorX technology, featuring an F1.0 super aperture that captures four times more light than F2.0 lenses and a highly sensitive 1/1.8" image sensor, delivers true full-color night vision even in dim environments without additional illumination, enhanced by adjustable warm lights and spotlights for minimal disturbance.

Advanced AI detects persons, vehicles, and animals to minimize false alarms and enable precise alerts, including line crossing, zone intrusion, and loitering notifications for perimeter protection.

Two-way audio facilitates real-time communication, while a built-in siren and spotlights deter intruders upon detection. Powered via PoE for simple single-cable setup, it supports versatile storage like microSD up to 256GB, NVR integration, or FTP for 24/7 recording, with IP67 weatherproofing ensuring durability in harsh weather—ideal for subscription-free home or business security via the Reolink app.
