Here is the screenshot of the recording setting on my NVR. Just wondering if it needs some optimizing. For exemple if there is a noticable difference between Image Quality 6 and 5. And for Bit Rate what benefit can I get if i increase it from 4096 to 6000? I know there is always a compromise between video quality and storage size, Just trying to find a sweet spot where increasing Bit Rate and Image Quality will not gain a noticeable difference.
And once I finish the recording setting here do i need to go to each camera and update the settings there as well? Thanks,
