Grandstream Networks GXV3601 Some notes on using SD cards / USB drives, Port forwarding

GXV3601 IP Camera

You must set the video resolution to QCIF to watch the GXV3501/3504 /3601 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 GXV3501 /3504 /3601 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 / USB drives.

1.The GXV3501/ 3504/ 3601 only supports FAT32 formatted USB drives

2.The GXV3501/ 3504/ 3601 support SD and SDHC

3.It takes 10-15 seconds to read SDHC and USB drives with large memory capacities. Please wait 15 seconds to unplug the SD/USB drive after you plug them into the device.

4.If there are many files (ie. 1800 or more image batch files) on the SD/USB drive, it can take up to 5 minutes to read them. Please do not refresh the web interface at this time as the GXV3501/3504 will restart reading the SD/USB drive. Grandstream is currently working on a fix for this issue.

5.Why is there a black / flashing bar at the bottom of the video feed?

This can occur if the GXV3501 /3504 does not recognize the standard of the connected camera. If you experience this issue, please restart the GXV3501 /3504. The GXV3501 /3504 will detect the standard of the connected camera and use it when the GXV3501 /3504 boots up. To avoid this make sure to connect analog cameras before booting up the GXV3501 /3504.

6.Port forwarding

Two ports must be forwarded on your router to watch video from a GXV3501 /3504 /3601/3611 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.
