Installing on PVC?

Hi, was looking at the video doorbell 2nd generation, however I have a complete porch at the front of my house so I can’t install it on brick, it’s all uPVC. I’ve seen online that it can be difficult to install on uPVC unless using adhesives, which sounds like it would be easy to steal? Does anyone have an experience with installing on uPVC porches etc, that would be able to let me know if it works on there or not, and how easy the installation is? Thanks.
