Hi,
I have a Dahua Sd52c225u-hni. It has been working great for a number of years. Firmware is 2.812.00000009.0.R (might be one more or less 0).
Nothing changed on my network, no firmware upgrade, working fine for a number of years. My DVR didnt have the image, so I logged in, checked settings, looked OK but I did enable multicast (which was disabled) as I was matching another camera settings, saved, then did a manual reboot (it does daily reboots).
So the camera comes online, responds to pings, when I do a port scan it shows ports 22 & 8088 open. The dahua config tool sees the camera but wont let me perform a factory reset. Wireshark shows the camera on the network.
The cameras are on an internet-less vlan so not sure if that is whats causing the issue. I access the camera from BlueIris, not using P2P.
Any suggestions on what I can try? I shut it off for 5 minutes but that hasnt helped (yet).
Thanks,
Rich
EDIT: It looks like SSH comes on for 10 seconds? I am able to login for a moment before it closes the connection:
Not sure what I could do within the SSH shell but figured I would try - sort of sucks it closes so fast.
