I've had a couple app updates, now on 3.1.2 build 1318. Things seem "better" but I've been reformatting when the cards get full and viewing response gets flakey. I have not seen any firmware updates. I have two 411s with 128G cards and two 420s with 256G cards. All 4 have exhibited the viewing "stall"  at some point but the 411s have always performed better. I keep meaning to swap the cards, putting the larger cards in the 411s, to see if that helps the 420s.

Right now I'm more frustrated by the app nagging to use 2-factor every couple uses. And the fact that the latest version doesn't open on the last viewed page. You have to select the camera tab every time.

Viewing performance: better than two months ago but not 100%. App experience, worse than previous design.

Thanks for following up though, I appreciate it.

Update: 411s on 2.3.14. 420s on 2.3.15. Must have been an update without the firmware check page. Last checked in June and 420s were 2.3.13.

  @Riley_S I have 5 KC410S cameras and all are still on the debug 2.3.14 firmware.

One of the cameras had the issue recur with that firmware installed and I notified developers, it then recovered on its own and began recording again. It's still working currently.

The four other cameras are in the problematic state currently and have not recovered (no 24/7 recording).

Whatever they've done, the developers haven't fixed the issue on these cameras or at least haven't pushed the firmware fix to mine.

Also I'm using the Kasa app version 3.1.2 | Builld 1318 on iOS 16.1.

When the camera reaches card capacity, it sporadically overwrites. I'll see a couple recordings from the current day but nothing on the day or two before. Go back 3 or more days and there's fairly normal recordings. Trying to view any of them is mostly just waiting and probably nothing happens.

This was all before though, like I said it's been better tha past could weeks. It stil happens though.

I could use smaller cards but I specifically bought higher capacity cards because they were listed as supported..

Thanks again.

My 410S cameras are still on 2.3.14 while my 400 and 420WS cameras are on 2.3.15.

One theory I have had about this but (not mentioned in this thread) was that when I travel and go to a different time zone, I felt like this corrupted recording bug showed up then (something to do with the App/Camera wanting to adjust to my current time zone and screwing up the recording files/directories).  But agree this seems likely to be timing of when the cards fill up.  In my case, when I pull the card(s) and try to view files, I find only a 00 and 23 directories and all of the files are 2487 KB in size (very small) and won't play anything.

Until the bug fixed is confirmed, it might be best to reformat cards about the time they fill up and start trying to overwrite and/or when you think there's been nothing unusual to go back and look at.

I did just have an incident a few weeks ago I wanted to check and both the front yard 400 and 420WS cameras were not recording anything for several days.  That's kind of frustrating but everything turned out okay in this case and reformatting the cards has these cameras working great again.  I really like/want the 24/7 recording so that's a key feature that Kasa needs to get right.  Hoping the .15 firmware solves this.

Only as a follow-up. My two 420s on 2.3.15 haven't had any issues in the past month. I turned the resolution down to 1080 about 6 weeks ago and formatted the card. Now it has filled the 256GB card and is continuing to keep new recordings, presumably deleting the oldest ones. My 410s on 2.3.14 seem to have missed a few recordings.

I haven't had any corrupted playback issues recently either.

I've turned it back to 2160 now but didn't reformat the cards. I'll keep watching.

  @RP707 Brief update - all 5 of my KS410S cameras and the single KC420WS have updated to firmware 2.3.15.

All except for one are now working as expected for 24/7 recordings.

A single KS410S has had 24/7 recording stop at some point.

I reformatted the SD card in that one and am waiting to see if the issue recurs.

  @Riley_S The one KC410S showed the SD card was full at the time the 24/7 recording stopped.

The app indicated 0.00 GB Available/ 226.32 GB Total.

The camera is in a different location than I am, so unplugging/plugging is not an option currently - I'll try power cycling if it happens again and I'm at the location.

Would be nice if one could trigger a power cycle for the camera remotely.
