The Reolink DUO2-4KWS, an advancement of the Duo WiFi, can merge two views into a seamless 180° panorama without overlapping parts, effectively creating a true combination of two cameras. It not only offers a wider field of view but also a longer focal length than conventional wide-angle cameras. Even with an expanded viewing angle, the entire environment can be captured sharply in Ultra HD 4K. Every small detail can be captured with precision.

The intelligent detection of the Reolink DUO2-4KWS has also been optimized. It can recognize moving people and vehicles as well as pets. The built-in microphone and speaker make it easy to respond to unwanted actions from pets or communicate with visitors. Currently, only dogs and cats can be detected (Beta version).

With spotlights and infrared LEDs, users can choose between color or black-and-white night vision. Both options can capture the night in a clear and smooth manner. The Reolink DUO2-4KWS supports motion recording, 24/7 continuous recording, and scheduled recordings, which can be stored on an SD card of up to 256 GB (microSD card not included), a Reolink NVR, or an FTP server.
