For simplicity - assume you just bought a house on 20 acres in an area that doesn't see much snowfall. There is a dirt trail that runs 100y to a (not busy) county road. The property is mostly wooded and overgrown. There is no fence at all.

Starting with day 1 - the moving truck just left and you are all unpacked.

What do you do to protect yourself from 2 legged and 4 legged predators?

Cameras? Where? What kind? Game cameras hooked up to cell networks with phone notifications? At the gate? Ring cameras around the house?

Gate (automatic/manual)?

Lighting? Motion activated or on all night?

Fencing? Barbed wire?
