I run 13 cameras, all Dahua (EmpireTech). I'm slowly going through each network setting just to make sure things are in order. Anyway, in relation to Network/QoS the settings are the default setting of 0 out of 64. With these settings I have no issue with monitoring live feeds or recording, in Blue Iris. I understand if set that it informs my router (udm pro) to give the feed more priority but I'm not sure how that impacts the rest of my network. The CCTV system is on a VLAN. I notice at times, most times, when I have the web browser open for any camera the live feed (in the browswer) goes blank and get the windows circle thingy rotating. At these times I also have BI on and viewing the same camera.
Should I leave these settings as they are?
