If you throw in a classifier for detecting dog poop, and ideally, urine, I will buy five of them, place them around my home, and ensure the floors are clean before sending an API call to start my robotic vacuum. Thank you. Edit: there is a market! https://news.ycombinator.com/reply?id=26916974&goto=item%3Fi...

Speaking of, does anyone know of a good dog poop image classifier?

Well, you can do some basic things with this but honestly RPi4 is pretty much underpowered CPU for any serious AI. You can run some optimized networks probably even 200 fps like TinyYOLO linked below but it will always be a tradeoff between accuracy and hardware capabilities. If you want AI you'd better consider Jetson or figure out some other DNN accelerator.

For many applications 1 fps is plenty though

What I would really love is a camera looking out each side of my house and one upwards, looking at both ground and sky. Train it over the span of a year. And then notify me whenever something novel happens.

Beautiful sunset? Let me know. Strange car parked in front of my house? Let me know. Neighbours house on fire. Backyard intruder. Flooding. Etc. Anything sufficiently new that the camera hasn’t seen before.

Is there anything for that?

The problem is that something as ambiguous as you described requires human-level AI.

But if you could accept portions of it, you could build a detector for unusual vehicles (would yield a lot of false alarms). And a detector for beautiful sunsets. A system that would recognize individuals by gait and be trained by you for specific authorized persons. A detector for water on the ground.

It's possible to just detect any movement or significant change in the scene, but that would yield quite a few events that were actually not interesting. Like birds landing.

Jetson Nano does not seem a lot better than Rasp Pi to me. Nvidia Xavier NX is a different story.
