Had a WOC fail and Wyze replaced it.
Could not find any information on how to take it apart so I went in and only managed to break 2 small clips holding the battery cover down.
The lens can be focused just like the v3.
There is one screw that can be difficult to remove. It is down inside the camera. The printed circuit boards are attached to a carrier which slides out of the housing once this screw is removed. Don’t use a Philips screwdriver with a pointed end. The drive is very shallow compared to the other screws, so a nice pointy Philips screwdriver will bottom out and the head will be damaged
