I am a Wyze user, just like you, trying to help you. I don’t work for Wyze. I volunteer here in the forum to assist other users.
You are correct, I am confused about what you wrote. Because the terminology you are using is what is causing the confusion. “Playback” or “Playback Video” is a term Wyze uses for SD Card Video only, not uploaded cloud video.
“Events” or “Event Video” is the term used for Wyze Cloud uploaded video which is shown as individual video clips in the Recent Events or the Events tab for the Wyze Cam OG.
Without an SD Card in either of the the cams you previously posted which were removed due to language, you cannot access SD Card “Playback”.
In the OG Cam, that SD Card Playback is accessed by (1) clicking the SD Card button in the Live Stream toolbar above where Recent Events is shown; or (2) clicking the SD Card Icon labeled “Playback” while viewing an Event video from the Events tab. Without an SD Card, clicking either of these buttons will result in a message stating no SD Card is installed.
On the OG Cam with the Cam Plus Subscription you have, the “Recent Events” that show as video clips at the bottom of the Live View screen are a short list of Events that have been uploaded to the Wyze Cloud Server and are being streamed back down to your phone when you view them. The full list of Events Videos from that cam for the past 14 day history that is saved on the Wyze Cloud Server can be accessed from the Events Tab. Again, when you watch these Event Video clips, you are streaming them from the Wyze Cloud Server back down to your phone.
The only time you should see an SD Card not Inserted error is if you try to click on the SD Card icons shown above.
You are not required to have an SD Card installed. The cam will operate on Cam Plus and save all Event video to the cloud for you to view in Recent Events or the Events tab without an SD Card.
Uploaded Wyze Cloud Event Videos and SD Card Playback Videos are two separate and independent video recordings that are accessed in seperate ways. I recommend all cams have High Capacity High Endurance SD Cards installed recording Continuously if for nothing else but security video backup in case video Event uploads are interrupted due to an internet outage.
If, however, you are getting an SD Card not Inserted error when you are clicking a Recent Event or an Event video clip, that isn’t supposed to be happening and you may need to upgrade your firmware or app or reset your connection to the server.
