How is Wyze Cam Pan v3 different than Pan v2?

It has a new design, weather resistance, and so much more. 

Wyze Cam Pan v3 has an entirely new, innovative design that doubles the total tilt range to 180º and produces 40% less dBA noise when rotating. It is also our first IP65-rated weather-resistant pan camera, ready to be used outdoors. It has an included mounting kit that lets you mount it literally anywhere - even upside-down. Lastly, it has Privacy Mode which points the camera lens down towards the camera body and obstructs any view.
