I recently installed some wired CCTV cameras and a network video recorder. The cameras are streaming happily and the recorder records just fine most of the time, but approximately 100-150 times a day I have missing 30-90 second stints. On investigating the HH logs I'm seeing this:
01:36:46, 06 Jan. eth3:An Ethernet port is now connected (4/100/FULL)
01:36:43, 06 Jan. eth3:A device has been disconnected from an Ethernet port (4)
These times match the missing data, and show disconnection of the network recorder which is hard-wired into one of the rear ports. I'm surprised as I thought it would be the cameras over a TP-Link powerline connection!
I can see no reason for the PNR dropping the connection (new cable, tried another, short Cat6E cable).
Can anyone think of a decent way of identifying the cause?
Welcome to this user forum.
I am sure this issue has been reported before.
What make of CCTV/DVR cameras are they?
Did you try a different port on the home hub?
Have you got a spare network switch that you can connect between the home hub port and the network recorder, as I seem to remember that is what the fix was?
It could be the DVR or the home hub, or some form of mismatch. If you can interpose an Ethernet switch between the home hub and the DVR, to see if it stops the disconnects. It would also allow you to see which end is dropping the link.
There is another similar post about this in the forum, which I will try to find.
