There are multiple wifi-connected solar powered cameras that will do the motion-activation, IR night mode, etc. thing that you’re asking for, that you can just drop into a location, but they won’t be self hosted.
Unfortunately pretty much everything you’d self host takes time and finagling, it’s just the price of privacy/independence. I know you’re asking for a self hosted solution but that will be difficult with little free time. I’ve been running frigate for a year and I still can’t get some object detection masks to properly ignore detections.


You got it! Best of luck with the baby
