    LOADING...

    The Reolink CX820 is an 8MP 4K PoE outdoor dome camera with ColorX color night vision, HDR, and smart person, vehicle, and animal detection, suited to homeowners and small businesses seeking detailed, wired security coverage.

    Recommended For

    • Homeowners or small-property operators who can run Ethernet and PoE to a fixed outdoor view—such as a porch, driveway, or side entrance—and want 4K recording with person, vehicle, or animal alerts.
    • People monitoring entrances, driveways, or yards with some ambient light who want to see nighttime footage in color; CX820 owners report strong results with street or exterior lighting, while performance is less suited to completely dark scenes.
    • Users building a wired Reolink or local-recording setup who want an outdoor camera with smart person, vehicle, and animal detection rather than a battery-powered camera.
    • Property owners who need a fixed, aimed view—such as a particular gate or doorway—and value low-light color footage more than camera movement or optical zoom.
