Is there anything that can mount a v2 to the outside of a window?
Welcome to the Wyze community @oaklane76!
If you place the V2 in a housing with a tripod screw, then use a suction cup mount, you should be able to attach the camera to the window. I have not tested any of these mounts so it’s guaranteed that it will hold. Also, the V2 is not an outdoor rated camera, so the warranty I’ll be void if it’s used outside.
You can use a V3 and connect it to a suction cup mount with the tripod screw(on the V3). There is also a interior window mount available for the V3.
