13. How to use a cell phone to watch the GXV3672HD_FHD video stream?
You must set the video resolution to QCIF to watch the GXV3672HD_FHD video stream from
a cell phone. Make sure to set the bit rate to 64kbps to ensure the best video quality.
14. Why the IP address of the device NOT reset when clicking the “Restore” button?
The GXV3672HD_FHD could be installed in areas that are not easy to access. For example,
it could be installed on the roof of a building or the ceiling of an office. This makes it difficult
to reinstall the device, therefore the “Restorefunction will not clear the IP address.
15. Why can’t the live video stream be viewed using a mobile phone or GSurf_Pro
after changing the HTTP Port of the device?
Make sure that the RTSP port of the device is set to 2000 plus the HTTP Port number. For
example, if the HTTP port is 88, then the RTSP port of the device that you configured on
GSurf_Pro or mobile phone should be 2088.
16. Port forwarding
Two ports must be forwarded on your router to watch video from a GXV3672HD_FHD that is
located on a private network from a PC in a public network. The web port (HTTP) and the
RTSP port. Please make note that the RTSP port number changes according to the web port.
If the web port is 80, then the RTSP port is 554. If the web port is not 80, then the RTSP port
equals the web port +2000. For example, if the web port is 88, then the RTSP port will be
2088.
