Interference in footage

[jackl123]

Lately, my Frigate footage has intermittently been picking up blocky shape artefacts (for want of a better term - see attached screenshots to see what I mean) which aren't on the original camera stream. Does anyone have any idea of what could be causing this and/or what I can do to prevent it please?

I'm running HA on a Raspberry Pi 4, and wonder if it's a sign of the hardware struggling or something else.

Typically I see this when a camera uses UDP rather than TCP and there is packet loss. Both of those examples could have been eliminated with a min_area filter for person.

Got it, thanks for your reply

I had similar issue with reolink camera and rstp stream.
I have swapped to http and it seems to have gone away.
