6. Why does IE indicate to install Grandstream Video Viewer add-on after a firmware
upgrade? The add-on was properly installed before the firmware upgrade process.
New firmware will often upgrade the add-on as well. To watch the live video stream, you must
install the newest version of the add-on.
7. How do you watch secondary video stream?
Login to the home page of the GXV3672HD_FHD web GUI, click Play to watch the video
stream. To watch a secondary video stream, right click on the video, and select Secondary
Stream on the pop-up menu. Try reinstalling the Grandstream Viewer add-on for IE if you
cannot see the video stream.
8. Why is audio missing from the recorded video when an alarm triggered?
To confirm to outdoor standard of IP66, GXV3672HD_FHD does NOT have microphone
installed although it has the interface in its PCB board. That is the reason of no audio.
9. What is DDNS? Is it important for IP surveillance product to have DDNS support?
DDNS is an acronym for Dynamic Domain Name Service. It is important to choose an IP
network camera that has DDNS support for dynamic IP addresses. Chances are that the
network has a dynamic IP address (which changes with every log on). A DDNS service makes
sure that the camera‘s IP address always matches up to the current server address. DDNS
also allows a website to be linked to the IP camera that is constantly updated with the correct
information and has a reliable feed.
10. Why is Windows Media Player unable to play the recorded video files?
The GXV3672HD_FHD uses the H.264 video codec. Windows Media Player may lack the
proper H.264 decoder to play the recorded video. Please download the Microsoft FFDShow
H.264 decoder from http://sourceforge.net/projects/ffdshow-tryout/
and install it.
11. Alarm Triggered Events do not work with Surf_Pro?
Please double check the Alarm Action on your GXV3672HD_FHD. Login to the web GUI of the
GXV3672HD_FHD, go to the Motion Detection or Alarm Events page, and make sure option
Upload to Alarm Center is checked.

recorded files you need.
