Not new to Dahua IP cams and have read the wiki 100x. Just got an IPC-B5442E-ZE to augment my system from Andy's Amazon store. Powered her up via POE switch, and all was well. Changed the IP, grabbed the MAC, reset, and all was fine. Stepped away and powered her up again and can't get an image. Tried Pale Moon, NACL,.... nothing. Did a factory reset, nothing. Tried several POE injectors, external power, nothing. Sometimes I can't get the settings tree on the left to work, sometimes I can. I've been trying to get the FW version and can't get the tab to work. What am I missing here? She worked, now she don't?
