Have been desperately wanting something like this so I can build an AI to detect when people don't pick up their dog shit in front of my gate. I am saved.

You can get the latest most powerful Raspberry Pi and connect any decent compatible camera, find a telescope adapter, and run something like Tiny-YOLO. That will save you around $200.

I’m not sure if you’re serious but this is pretty overkill for that.

If you're serious, please do a write up. I'm sure TONS of people would appreciate a project like this.

  Seconded. If they built and blogged about this it would go viral I would think. :)

  Oh I'm dead serious. I want it to play an audio file when it detects a dog shit: "Thank you for kindly picking up your dog shit."

Just get a fake camera with a light and put it in an obvious place so everyone that walks by notices they are being filmed.

You probably want to mount a weather-resistant camera outside. You could buy an eg Reolink security camera for this fairly cheaply. [1] Then you can stream the video to a Raspberry Pi 4 + Coral USB accelerator, an nVidia Jetson nano, or the like and do analysis there. [Edit: oh, I missed that the Vizy has an outdoor enclosure available. Still, it's extra $60 and is huge/ugly. The off-the-shelf IP camera + separate computer for analysis should be cheaper and IMHO better.] I'm working on a Free Software security camera NVR system. [2] I have a pretty solid core recording engine now and am just thinking about what the API for on-NVR analytics plugins should look like. I'm imagining a Python API where you write some coroutine that can iterate through decoded video frames (either live or backlogged) and make calls to your favorite ML frameworks; add events, object detection tracks, and other metadata to the database; instruct that MQTT messages be sent; etc. If you're interested in using this kind of thing, I'd love to talk more. [1] I used to recommend Dahua or Hikvision, but it seems they're actively supporting the Uyghur genocide via custom software, eg <https://www.latimes.com/business/technology/story/2021-02-09/dahua-facial-recognition-china-surveillance-uighur https://www.latimes.com/business/technology/story/2021-02-09...>. I won't be buying any more cameras from them; I'm sure my boycott will devastate their business and cause them to reconsider their position immediately. As far as I know, Reolink is uninvolved, despite also being a Chinese company. [2] https://github.com/scottlamb/moonfire-nvr https://github.com/scottlamb/moonfire-nvr
