Same here but for urban foxes.

We had motion triggered sprinklers that worked great, but they did not differentiate between foxes and 4 year old children if I forgot to turn them off haha.

We have more or less 360 degrees CCTV coverage of the garden via 7 or 8 CCTV cameras so rough plan is to have basic motion pixel detection to detect frames with something happening then fire those frames off for inference (rather than trying to stream all video feeds through the algorithm 24/7) and turn the sprinklers on. Hope to get to about 500ms end-to-end latency from detection to sprinklers/tap activated to cement the "causality" of stepping into the garden and then ~immediately getting soaked and scared in the foxes brains. Most latency will be for the water to physically move and make the sprinklers start, but that is another issue really.

Probably will use a RPi 5 + AI Hat as the main local inference provider, and ZigBee controlled valve solenoid on the hose tap.
