People have used H.264 Hik with Blue Iris no problem AFAIK.
Please come back and let us know how it works, as this is a cheap Chinese market only camera which I think plenty of people would like to know how it gets on with BI.
I am using a synology NAS to record the streams and it seems it doesn't support h265. So can anyone confirm this camera (or any of the h265 hikvision) also capable of providing h264?
