Whenagain To connect to your WiFi network, follow the included instructions and prompts from the camera and the Yoosee App. Once connected, you can get the camera's MAC from a simple network scan, then you can make an IP address reservation on your DHCP server. This camera does not have PoE functionality, though you could technically run it with power from a PoE connection with a PoE to ethernet-MicroUSB splitter.
