ok, I'm still seeing something weird here. I'm using Firefox.latest on Win10.latest, 64 bit fast desktop, etc. On the Camera->Conditions tab, or any of the other tabs that show a thumbnain, every few seconds, that thumbnail blanks, a time spinner runs for a second or two, then the video comes back. 5 seconds later, does it agian, over and over.
now, I currently have the substreams disabled, and
blueiris is running on a different dedicated NVR miniPC. on my large highres displays, the substreams are ugly even when they are smaller preview windows, and with 7 cameras, my core i7-6700 NVR seems to keep up just fine. I'm also not using any in-camera motion detection, because I have a motley fleet of 3 camera brands, 3 reolinks, 2 hikvision, and 2 different dahuas, an empire and a amcrest and getting all that sorted smells like work, and this is for fun at home.. If I had all Dahua 5442's, I'd probably be moving to camera detection, although the camera's webUI seems pretty convoluted.
