Hi  @Wayne-TP,

Thank you for the reply.

No, I did the same as in case of that when the SD card was put directly into the camera, started from the oldest or older video, set the playback speed eg. 2x or 4x and just (tried to) watching records after each others.

Since I created this thread, found that this is a random issue and not affects all footages.

I found these further symptoms:

 - sometimes the app plays video than properly starts the next one once the previous ends but

 - there is no guarantee if the next next video will be found and playback starts

- and sometimes the playback skip few clips and starts playing a clip recorded sometimes later. For example, I was watching a clip recorded at sometime around 6AM and the app/HUB skipped some of the next clips and started to play an another recorded at 9AM.

It seems, the app/HUB doesn't recognise the next video and skip or miss the following recordings.

I didn't put the SD card into a computer and check e.g. filenames or creation date and time.

And I don't know the logic how the app/HUB determines which recorded footage is the next, maybe this is the problematic part or it doesn't save files in consecutive order.

Of course, I checked the app version (it's 3.12.108) and tried it on different Android device - result was the same.

And random slowness within the clips is also there on the another device (tablet).

Thank you.

Thank you @Wayne-TP

Email from the support has arrived.

I'll continue with providing further details, screen recordings.

  @SecCamFan Any update with this? I too have the C520WS which I orginally had the Micro SD in and it worked perfectly. I have since got the H200 hub with the camera recording to the hub. I am experiencing the same issues with the slow playback also when watching footage from continous playback, when an event happens it says no video and I have to press the event at the bottom for it to play.

Hi @JAYZ303,

I'm still waiting for the new firmware.

TP-link support informed me about that the issue investigation is still in progress on R&D department's side. As they found in the logs, there is an issue with the timestamp - date in the timestamps is not matching with the real date of event detected and recorded.

Once you have free time, please check this thread:

https://community.tp-link.com/en/smart-home/forum/topic/827066

I mentioned there another strange behaviour - missing recordings even if we were there in FOV of the C520WS camera

I'm curious if you have this kind of issue as well. If yes, we'll need to raise that...

Thanks.

  @SecCamFan I can't say I have experienced any issues regarding lack of activity detections or even false alerts.

For me it's purely just playback that seems to be bugged. Do you have the issue whilst on playback just before an event there's a small black line which indicates no recording but if you let it continue playing up to the event it will just skip the entire event and continue on the next non-event recording? 

It's hard to explain so I have attached a gif to show what I mean.

Hi, @JAYZ303,

Yes, I understand that you described.

I didn't experience same behaviour because I don't use continuous recording.

We have different recording settings - continuous vs. event triggered.

Probably, this is why we experienced different issues with playback.

The responsible engineer from TP-Link informed me about that the new beta FW can be released next week...
