The camera is compatible with the Cloud Gateway Max as it is part of the UniFi ecosystem. The camera's AI functions, such as people and licence plate recognition, are also available when connected to a suitable UniFi system. The Cloud Gateway Max supports multiple UniFi devices and provides sufficient capacity to manage network cameras.
The AI features of the "AI Pro (3840 x 2160 pixels)" camera from Ubiquiti work with the CloudKey+, as the camera itself has advanced AI functions. It is not mandatory to use the AI Key to utilise these functions. However, the AI Key could provide additional AI functions that go beyond the standard capabilities of the camera.
I just checked and you are right, this network camera is connected to the network via LAN, thanks for the hint! I will revise the incorrect specification as soon as possible.
