I started with a combination of Raspberry Pi + Pi camera running motion - and then moved towards Ubiquiti with their PoE cameras and their NVR software.

This was when their NVR software came as a Debian package, and was well supported. It meant I could run up syncthing against the local instance to (near) instantaneously share new videos across from my remote network, on a satellite connection, back to my home network.

Ubiquiti now appear to have abandoned support of the run-your-own NVR approach, and instead are pushing dedicated devices, which remove a lot of the flexibility to use them as you see fit. Their motion detection is also done within the NVR, not the camera module itself, so you need an NVR close to the camera(s).

I mention this as the price in Australia for the entry-level Unifi camera devices is about the same as a raspberry pi + camera + microSD card. Power consumption will be higher with the latter, but the tradeoff is that it's a proper GNU/Linux host, not just a blackbox appliance.
