OK no luck yet. Since the camera is 5 years old I decided to upgrade the camera firmware which I found on the Dahua site. I verified that the camera accepted the firmware update again updated the password to xxxx123 and checked to see that ONVIF was enabled.
Per someone’s suggestion I downloaded the sourceforge ONVIF Device Manager (same download is recommended by Dahua on their website). When I launched it,it showed the camera’s IP 192.168.1.108 on the left hand side of the screen, however on the right hand side none of the click buttons showed anything about the camera (eg. Identification button resulted with error: “The remote server returned an unexpected response. Network Setting button resulted with error: “Sender not authorized”. So it does not seem that it is working properly. Got same result prior to and after camera firmware upgrade.
Then, with the camera plugged into the POE switch I tried again to “custom add” the camera and got the error “network is unreachable”. Then I plugged the camera into the NVR and tried again to “custom add” it and got the error “username or password is wrong”.
Then, I went back using the Config tool and changed the camera IP to 192.168.254.2 and gateway 192.168.254.1 and plugged the camera back into the NVR. Again, got the error “username or password is wrong” (even though I used the same password for the camera and in the NVR when trying to add the camera – password xxxx123)
Then, I plugged the camera back into the switch and launched the ONVIF Device Manager again. When I logged into the Device manager as admin, admin, it did not see the camera. So I logged in again to the Device Manager using admin, xxxx123 and it could see the camera on the left hand side of the screen (with IP 192.168.254.2). However, on the right hand side of the Device Manager screen it gave the error “There was no endpoint listening at http://192.168.252.2/onvif/dev.....ce_service that could accept the message …”.
So this is where I am stuck. Seems like an issue with the ONVIF?
