Well, I missed when it started recording over the part of July 13@2300.
When I checked today (7/27/21) @1430 the earliest clip was July 13th @0800 and showing 114.2G used.
When I checked again @2000 the camera had overwitten up to July 14th@0500 and was down to 111.52G.
Doing the math that is 13 days, 15 hours of recording on SD. Not bad for an $18 card.
(Note the most I saw recorded on it was 115.2G., but that was with some HD from early on)
It gets a little flaky scrolling though the card, I have to go slow with the app. And sometimes when I scrolled all the way to the beginning it wouldn’t replay, but sat there with the live view.
