I agree with @jjr sadly its how the camera is going to view things that are close when the background, in this case the sky is much brighter.
if you are familiar with the camera on your phone, this is what the HDR mode is for , it basically take two photos, one for best light of the thing that is close, and one for the background and meshes them together.
some dashcams have an HDR mode for video and the results are amazing. but it takes much much more computing power then our wyze cams have which is more than likely the reason they are unable to implement it.
your best bet will be to mount it somewhere so the background to where the people you want to capture is considerably dimmer. I have the one for my front door mounted high and the light works out great using the ground as the background behind the person.
