Ended up being my router. We can all agree that the cameras are pretty awesome at a great price. But the software is really hit or miss. I solved my issue with camera lagging by connecting to a brand new router. Works like a charm now. And once your cameras are at a point where they are doing good. Stop doing firmware updates. My last update goes back to about Nov, 2021. Cameras have been working good other than my [Mod Edit] old router.
