I don't know if you had already solved your problem. I also have a Chinese WiFi camera running the Yoosee App.
To get it work with D-Link router, you may read the
Yoosee FAQ webpage.
Gwell, the real solution provider declared the camera uses the RTSP protocol to broadcast video stream.
rtsp://IPadr:554/onvif1
Main stream rtsp://IPadr:554/onvif1
Sub-stream rtsp://IPadr:554/onvif2
Additionally, please check these ports with your router for troubleshooting.
