Are you allowed to run your usb cables behind your walls the way you do a TV?

We have wired cameras and motion detectors and the wires running down the walls don’t look good, esp when I have the devices in the middle of a wall (vs in the corner where cables hide a little better).

Can you run usb power cables through the walls? Not sure how I’d do it but basically drop the wire down behind the drywall in between the studs. Is this up to code and are there risks of fire?

And if it isn’t allowed, can someone explain why you can do so with TV wires?
