Ring's claim is that the device can be set up in 5 minutes. If they were just talking about getting the device set up on your network I would agree, it is quick and easy. As you can see in the screen captures below, the first step is to download either the Android or iOS app and create an account if you don't already have one.
From there the app walks you through about a dozen steps. The set-up is done like many other cameras; first it requires you to connect to the camera directly and provide connection credentials for your home network. Then it connects and you are off to the races.
Once you have the device connected to your network you will be taken to the app's main screen and you can then start to decide where and how you want to mount this camera.
If you are using the optional solar panel you'll want to make sure whatever location you pick the cord is long enough to allow you to position the panel with good access to the sun. But with a 3 meter long cable you have lots of options. What I would suggest though is not to use the included hardware right away. Maybe try mounting the camera with zip ties or double stick tape until you find a good location for everything without making a ton of holes.
