This also works for the Wyze Cam v3 PRO model. I own the newer model and hung the camera upside down as the camera itself adds more support by leaning against the window. I added a string to the bracket to the curtain rod just in case the suction cups let go. I have the camera mounted high up on the window on the inside. I also use a Wyze Window Mount which is made of rubber that fits around the front of the camera and reduces glare. Helpful at night if you have glare seeping thru some curtains & blinds as I do. Works for new model as well. I did not use the tape for the mount as I have the camera tilted down which means the camera is not flush to the window.
