Grandstream Networks GXV3651_FHD user manual Some notes on using SD cards, Port forwarding

GXV3651_FHD IP Camera

You must set the video resolution to QCIF to watch the GXV3651_FHD video stream from a cell phone. Make sure to set the bit rate to 64kbps to ensure the best video quality.

14.Why doesn’t the IP address of the device reset when I click the “Restore” button on the Maintenance page?

The GXV3651_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 ―Restore‖ function will not clear the IP address. Press the

RESET button on the device for at least 6 seconds until you hear a beep to perform a factory reset of all parameters (including the IP address).

15.Why can’t the live video stream be viewed using a mobile phone or GSurf 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 / mobile phone should be 2088.

16.Some notes on using SD cards

1.The GXV3651_FHD only supports FAT32 formatted SD cards

2.The GXV3651_FHD supports SD and SDHC

3.It takes 10-15 seconds to read SDHC cards with large memory capacities. Please wait 15 seconds to unplug the SD card after you plug them into the device.

4.If there are many files (ie. 1800 or more image batch files) on the SD card, it can take up to 5 minutes to read them. Please do not refresh the web interface at this time as the GXV3651_FHD will restart reading the SD card. Grandstream is currently working on a fix for this issue.

17.Port forwarding

Two ports must be forwarded on your router to watch video from a GXV3651_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.
