Build a security camera system with Raspberry Pi Zero and cheap webcams

This project is very similar to an earlier project in that again we are using the MotionEyesOS: Build your own security camera system with Raspberry Pi and cheap webcams
The difference is that this time it uses the Zero W, and it involves setting up multiple Zero W's with a Raspberry Pi 3 as a hub.
With MotionEyesOS you can easily configure multiple "Remote MotionEyes" systems, making them all appear on one screen. When adding a camera it's a simple matter of telling MotionEyes to look for a Remote system. It then makes all the required connections, and causes video from the remote system to display on the dashboard.
In this video the guy chooses to upload any captured videos to a Google Drive account. I wouldn't do that myself, because Google is a 3rd party whom I do not know if they are entirely trustable. In my case I would have it upload videos to the Drobo sitting on my home network.
To implement "night vision" he used the NO-IR Raspberry Pi camera. This is a version of the Raspberry Pi camera that lacks the IR filter. You then buy an inexpensive IR light unit - the unit bought by this guy has a light sensor so it turns on the IR light when it's dark. As you see below, night vision with the IR light is excellent.
