Dahua DH-IPC-PDW3849-A180-AS-PV. This is a wide angle camera that is actually 2 cams in one. it stitches the 2 images together to make one ultra wide image. For some reason it will not display alerts in UI3. I've gone over the settings until I'm blue in the face and nothing works. I've set it exactly like other cams and no joy. It did used to display alerts just fine. I'm guessing a BI update broke it. Other than this problem the camera works fine. Any help much appreciated.
