Compatibility and Installation

The CX820 utilizes Power over Ethernet (PoE) technology, which allows for both data transmission and power delivery through a single Ethernet cable, simplifying the installation process. Before purchasing, ensure your network infrastructure supports PoE, or have a compatible 12V DC power source available, as the power adapter is not included in the package. The camera is compatible with Windows, Mac OS, iOS, and Android platforms, and supports standard browser access including Edge, Chrome, Firefox, and Safari. Users should verify that their preferred storage method—whether a local microSD card, an NVR, or an FTP server—meets their 24/7 recording requirements.

Does the REOLINK CX820 require a separate power adapter?

The camera supports Power over Ethernet (PoE), which provides power through the network cable. If you are not using a PoE-enabled setup, you will need a separate 12V DC power adapter, which is not included in the box.

What storage options are available for this camera?

The CX820 supports local storage via a microSD card (up to 512GB), as well as connection to an NVR or an FTP server for flexible 24/7 recording.

Can the CX820 detect different types of motion?

Yes, the camera features AI-powered detection capable of distinguishing between people, vehicles, and animals to help reduce false alerts.
