Good day! Can someone help me about this issue?
I bought 4 wyze cam 2. All of them works fine when they arrived I immediately tested them. But unfortunately one of them the camera got weird footage after I setup them 1 by 1.
Here’s a record that I uploaded. Thanks!
I would start with a factory reset of this camera: hold down the setup button for 20-30 seconds. Then set it up again. See if that resolves the issue.
Still the same after factory resetting and set up again 
The next thing to try would be to re-flash the firmware. See this:

If that doesn’t fix it, you’ll need to file a support ticket for possible replacement.
