Ethernet Connections and the WT-6
The camera can connect to existing networks via a third-party Ethernet cable inserted in the camera’s Ethernet connector or an optional WT-6 wireless transmitter attached via the peripheral connector. The connection is more reliable than that offered by the camera’s built-in Wi-Fi.
