Live view from Dahua camera freezes when someone enters field of view

The live view from my security cameras freeze for 10-30 seconds when someone enters the field of view.

  • By “live” view, I mean what is shown in a Picture Glance card or directly from the cameras local web view outside of HA.
  • I’m using “EmpireTech (Dahua/Loryta) 4MP 1/1.8” CMOS" cameras (IPC-T549M-ALED-S3). I have five cameras
  • The cameras are wired Ethernet via POA switches.
  • HA is using the ONVIF integration.
  • I have event detection and any local camera’s SDCARD recording disabled as I thought that might be causing the camera feed to freeze.
  • I don’t have this freezing happen with the camera’s direct web view if I have HA shut down. So it kind of looks like HA is doing something when someone enters the view. Maybe HA is doing something like requesting a bunch of stuff and overloading the camera’s direct view?
  • A given camera freezes when someone enters the view from another camera.
  • I have an automation that captures a snapshot of my front entry and texts the snapshot to my phone when someone trips an ultrasonic proximity sensor on my walkway. That works well. But when I go to HA to view the live view, whoever is there is gone by the time the Picture Glance card is un-frozen and starts updating 30 seconds later.
  • When I had local recording enabled on the cameras, the recording was continuous without gaps or freezing during this event.

Anybody seen this?

I figured this out. I was testing this by walking from my home office to the exterior camera location. This, while watching the “live” view on my Surface tablet. As I moved from my Wi-Fi access point in my office to the one at the end of garage, the feed would freeze for sever seconds as it was changing the route.

But I was also chasing latency issue. I think I solved that by changing from Duck DNS to Nabu Casa for remote access. I also upgraded my HA server to an N100 mini PC.
