In Amcrect View Pro, when I use the Snapshot icon in Live View or Playback with my Smart Home ASH21 camera, I get a full resolution snapshot. The same is true when using PC Amcrest Surveillance Pro.
Maybe this would also work with your Smart Home AD410. I don't know how it would affect your Home Assistant implementation.
AD410 Snapshot Quality Low
Re: AD410 Snapshot Quality Low
Asp crashes when you try to access ash21 or the 410 for me and some others anyway. Also on AVP as well even removed and reinstalled app today still crashes trying to access 410 snapshot area also won't play jpg of cameras with images for me anyway
Be Safe.
