Thanks for that little tip, and on my 2 cameras disk usage is only 5%.
That was my one camera that updated online via the GUI. Maybe it happened during the upgarde? Fixed for now anyway.
Something I’m noticing with the camera thats giving me all the issues is the metal window frame is messing with its WIFI. That window has aluminum flashing on it. If I rest the Pi right on top of the window sill with the wifi antenna close to the metal surface the FPS drop dramatically. Les than 5 FPS some times. Prop it up a bit on something non metallic and they perk up again, +10 FPS. Take it out of the window and I get around 20 FPS.
