Hi,
I have some Dahua Speed-Dome and have do a mismatch in the config, so I try to reset the cam by press the reset butoom inside the cam. But that does not take any effect.The cam are not change anything and I get response an answer by the old IP, but I can't get access via telnet or webbrowser. Only ping are possible.
I need help for that problem. Any idea what can I do?
