"Connection dropped by remote end" and blue frame

[Turbid]

For some cameras (D-Link DCS-910, DCS-930) every 10-60 seconds I get these errors:

Code: Select all

and related events are falling blue frame.

Cameras are configured in a mode modetect and have sources:
DCS-910: /VIDEO.CGI? or /MJPEG.CGI?a=.mjpg
DCS-930: /image/jpeg.cgi

I tried to change the resolution from 640x480 to 320x240, but nothing has changed. Network connection to the camera is stable.

I had the same problem with an AXIS 207W Cam...

The problem was in the config of the cam, the "Bit Rate Control" in the MPEG-4 Settings was set to a maximum of 3000 kbit/s
