Substream bitrate similar to main stream

I am using substreams and CBR on the main and sub. It looks like the sub bitrate is almost the same as the main on most of my cameras. Should I be using VBR on the sub? Otherwise it seems I am not seeing an advantage of the sub.

The "normal" configuration for sub streams is to use a very low resolution for the sub stream, like D1, and I set a CBR that gives me a reasonable picture. Apparently, you have the sub and main streams set to the same resolutions. Be aware that you will need to re-configure motion detection for cameras using the sub stream since the resolution change effects the overall view for detection.

I don't think so.

You may not think so, but that's how I run my system and it works fine. Sub stream rates are between 10-20% of the main stream rates.

Please look at my settings. I have the substream set to D1 as you suggested. I do have the bitrate set to the default of 512 which I could lower I guess.
 
You settings don't mean much without knowing what camera it represents in your camera status capture.
 
The issue may be how I am referencing the camera in BI. I have the substream set to '/' which is probably not correct.
 
Well, it is running at 4.1 MP main stream, and 4.1 MP substream. Most of your cameras show this. Not sure how this happened, but, that is what the status window shows.

This is what I get if I do the Inspect. If I do this I don't get a sub so I add a / so yeah this is probably giving me the main stream on the sub.
 
Oops, double post.

I now have this and it appears to be working but not sure if it is correct.

Run "find/inspect" in the video configuration tab for each camera. The click the sub stream box and select the sub stream of Channel 1. Tis is a 5442T-AS identified as Front Yard East on the status capture.
