You’ll want to be running frigate, a self hosted nvr solution.

Camera wise, you’ll probably want a power over Ethernet (poe) amcrest or hikvision camera for continuous video to be sent to the nvr to do the detection. A list of recommended hardware is found here.

I’ll be honest though, depending on where this is you might be better off with a non-self hosted setup. For example, reolink makes several battery/solar powered wifi cameras that record on motion, shooting notifications to your phone. No cables to run
