I have a DH-SD49225XA-HNR PTZ.    which had worked flawlessly ( as did all my dahua cams).  We have another rainstorm yesterday and now I see no connectivity    I checked the ethernet cable with a POE tester and also swapped it with a known good outside cable.   the device will power on,  I can see the LEDS and the motor moves fine.
I cleaned the POE connection ( was a bit grimy) and still no connection. Any suggestions?
I guess I try full reset but I dont have the instructions for finding the reset panel. I think you take the top 3 screws off. they do not make it easy. Sorry for 2nd post in 2 days!!!
