Starting to work the sub stream as suggested but I can’t find Network IP camera configuration panel. I found this in the camera section my one and only.
Network IP camera configuration panel

Yes I’m bouncing back between the help section on sub stream subject and my camera log in information.
This is what I found.
The camera sub stream is exactly as it shows it should be in the help section Except maybe the bit rate. The difference in the bit rate, main 2048 and sub 512.
Also the resolution main, 2560-1440 and sub, 704x480.
Suggestion?
Hopefully everything I learn setting up this camera will be about the same as the others I purchase.

You'll set up the substream itself in the camera.
In BI, under the Video tab > Configure... button > Stream profiles > Sub is where you'll point BI to it.
For most Dahua cams the string for the substream will be:
/cam/realmonitor?channel=1&subtype=1&unicast=true&proto=Onvif
It differs from the Main by "subtype=1" vs "subtype=0" for the main.
The screen that you posted is just showing the current traffic flow from the streams.

With your help I think I’m getting somewhere. I accidentally hit the scroll wheel on my mouse and the information you gave me was right there. In the camera section it now shows the Main stream and Sub stream. The Sub stream didn’t show prior to this. Both streams now show about the same fps 30/0.50. The power consumption dropped about 3%. From approx. 8% to 3%. that’s with one camera.
30 fps is much too high for your purposes; Log into the cam's webGUI (a link to its IP is right there in BI on the "video" tab), go to video settings and on main stream lower frame rate to 15fps, set frame interval to match (15); change bit rate type to type "CBR" and bit rate to 4096 (as a start).

+1 above. You need to match FPS and iframes, especially if using BI AI.
Just keep in mind that "spec sheet wise" is under ideal conditions. Does your vehicle get the spec'd out MPG every fill up? I doubt it LOL.
Do a freeze frame capture of motion at night coming from 30 FPS. I bet it is a blur. But watching it realtime probably is silky smooth LOL.
Sure 30FPS can provide a smoother video but no police officer has said "wow that person really is running smooth". They want the ability to freeze frame and get a clean image. So be it if the video is a little choppy....and at 10-15FPS it won't be appreciable. My neighbor runs his at 60FPS, so the person or car goes by looking smooth, but it is a blur when trying to freeze frame it because the camera can't keep up. Meanwhile my camera at 15FPS with the proper shutter speed gets the clean shots.
Watch these, for most of us, it isn't annoying until below 10FPS

Ok did that and the Main stream and Sub stream dropped to 15/1fps.
What about the sub stream in the camera should I also change to the same settings in the Main stream. The numbers you recommended?
I can‘t see for crap with these old eyes but all the videos look pretty good except for the lower range being a bit choppy but they still look clear. I’m sure the camera used is of high quality. The one I have to be honest is pretty crappy. Next ones will be better I hope! Thanks for the Videos.
My 2MP cams' main is 1920 x 1080 and sub is 640x480, so set YOUR sub's resolution the next increment below your main's top resolution, FPS and frame interval to 15, bit rate type to CBR and bit rate to about 2048..see how that looks.
