This case study examines a connection issue experienced by a customer using Sanyo IP cameras with a GV-NVR video management system. The cameras would disconnect and reconnect periodically. Testing showed the problem occurred when directly accessing the cameras and was not specific to the video management system. The cause was determined to be an issue with the Sanyo cameras disconnecting and reconnecting on their own. The customer reported the problem to Sanyo for resolution.

- 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. GeoVision Inc. 2 Revision Date: 8/26/2010
