I'm sure I should know this, but I can't quite figure out how to calculate it. I have a client with a 31 cameras Hik system, newer with all 4MP cameras using H265+. They would like to live stream at another location on a PC using IVMS, 2 screens, all cameras playing simultaneously. They'll occasionally maximize/switch to live stream, but primarily with just have them sub streaming. How can I calculate upload/download bitrates, and thereby estimate monthly data requirements? Thanks!
