To use the
GXV300x
as a video surveillance camera, please configure the
GXV300x
and the monitor PC in
the same LAN environment. Advanced users may manipulate it to work over WAN (configuration not rec-
ommended and not covered in this User Manual). For best results, Grandstream recommends using this
feature in the same LAN environment or ensure both monitor PC and phone have static public IP ad-
dress.

. This is the only free open source player that
supports both the Grandstream device and RFC 3984.
2. Launch VLC.
3. Go to Tools -> Preferences -> Show Settings “All” (in the bottom of the page) -> Input/Codecs -
>Demuxers -> H264. Change “Frames per Second” value to 5 and then save.
4. Go to Tools -> Preferences -> Show Settings “All” (in the bottom of the page) -> Input/Codecs ->
Access modules -> Real RTSP. Check “Advanced Options” in the bottom. The option will show.
Change “Caching value (ms)” value to 1000 and then save. You may change it to a smaller value
to reduce the delay.
5. Close the Preferences window and go to File ->Open Network Stream:
•
Select RTSP as the protocol
•
Enter the URL in the “Customize” field using the format:
rtsp://admin:
ADMIN_PASSWORD
@DEVICE_IP_ADDRESS:DEVICE_RTSP_PORT
.
•
Change the text in red to your own configuration parameter:
i. ADMIN_PASSWORD is the phone’s administrator password for WebUI.
ii. DEVICE_IP_ADDRESS is the phone’s IP.
iii. DEVICE_RTSP_PORT is the RTSP port setting of the device. If the phone is us-
ing default value 554, omit the port portion from the URL
•
Click OK or enter Return key. Start viewing the video surveillance from the PC.
Limitations:
1. Video surveillance supports only two (2) concurrent viewers on the GXV. The video stream is set
at 5 frame per second and 128kbps.
2. The video stream will stop if a call starts. The video stream server (the phone) will not actively
terminate the session. Most clients (the VLC software in PC) will terminate the session after cer-
tain interval of time. A restart of the VLC software is required to view the surveillance again.
