I'm looking for something to run on a Raspberry Pi, to detect humans on a security camera. The built-in camera software has false triggering, esp. on windy days.

When looking at these projects, how do I figure out what hardware they're aimed at? This one mentions NVidia/CUDA.

Is there any sort of hardware abstraction layer that YOLO or R-CNNs can operate on? Can I use any of this code (or models) for my R-Pi?

Chezck out the Frigate project. It uses the Coral tpu accelerator which could be used with the rpi.
