Reading through this it is indeed the exact same problem I am having in my
BI recordings black screen post.
Also only affecting my 3 Dahua ipc-hdw5231r-z cameras set to H.265. My other cameras of different brand on H.264 are not affected.
The first one was affected 9/28, then the other two a day or so later started doing the same thing.
If I reboot the cameras through BI they begin to record clips properly but only for a couple of clips before going back to gray then black.
I too emailed support through the BI app.
My personal product support ran out just over a month ago. My response from them was not quite as customer friendly.
The reply was simply, "Please take the time to get back onto support and maintenance ... use the Upgrade/Renew button from the Options page."
Now I agree the application itself is great and a fair price and I don't mind paying for additional support of an issue I directly caused if necessary and I certainly don't expect anyone to just sit around answering my general product questions or resolving self inflicted issues all day for free. However, seeing as the issue occurred after an application update when I had made no changes, I do not see how it is applicable to my personally paying for further individual support. So I was a bit disappointed in that response.
