How come you don't fence your property?
While I'm no security expert, I have several layers of security at my house:
Property is fully fenced and gated, I have a remote controlled gate opener and key pad, if I buy anything online you can include the gate code in the shipping comments for the delivery driver, driver enters the gate 45seconds later the gate closes, driver leaves there is a sensor along the driveway gate opens and closes 45seconds later, property secured.
Roving dog patrol, sometimes this is a problem when drivers deliver, my dogs usually followed them out the gate, after a few times of looking for them I caged them on delivery days.
Security lights, I have a street light on my utility pole and motion lights on my back garage.
I have a couple cameras, I'll get more soon (better ones), I have WYZE cameras there inexpensive and will notify you immediately on your phone and back up to the cloud free for 2wks.
Hopefully it all stops at the gate!
