2. Problem Verification
Using the three methods listed below, we verified that the connection problem was occurring
on the cameras’ end as the cameras were disconnected frequently without the involvement of
GV-NVR.
• We tried to ping the IP addresses of the customer’s Sanyo IP cameras. The same
connection problem occurred from time to time.
• We tried to log into the Web page of the customer’s Sanyo IP cameras. When a second
user connected to the camera’s Web interface, the first camera Web interface became
disconnected. It was not allowed two users to log into the camera simultaneously.
• We used VLC media player (a third-party RTSP streaming player) to access the
customer’s Sanyo IP cameras. The cameras’ live streaming was also disconnected from
time to time.
Conclusion
After above careful verification, we concluded that the cause of the connection problem lies in
the Sanyo cameras since the cameras disconnect regularly even when GV-NVR is not
launched.
Result
The customer has contacted Sanyo to report the issue.
