Then you basically have an android phone on your computer. Since you already know how to use a phone, this makes it fairly easy to understand what to do. Once you open the Bluestacks program on your computer, just find and open Google Play and then go download the Wyze app onto it, and you can view everything through there just like on your phone.
Tiny Cam is a little more complicated, but it has a free version you can download, so you can see how easy it is for you to understand it. Here is an older walkthrough someone made for it:
Definitely a little more complicated to do that way though.
