When you live in an urban area your house is as safe when you go to work as the thickest pane of glass.
If someone wants something they will try take it.
Living off grid and remote is no different.
Locked gates and good signage are reasonable deterant but doesnt stop people.
Cameras are only as good as the power supply, wifi, or recording device and are easily knocked down with a stick.
If you feel insecure on your own land or in your own house you made the wrong choice.
Be aware of the law.
In Canada for example.
A trespasser must leave when asked to or face charges.
A returning trespasser faces charges.
Trespassing at night is a criminal act and indictable.
So tell them politely and firmly that they are to leave. No threats. Inform the police that you had a trespasser and try get proof pic/vid recording if possible.
Do not threaten a trespasser.
Do not assault a trespasser.
Most people including locals are just plain nosey, and aren't thieves. If you move to the area ands stay recluse, someone will come looking. If you are polite but firm and say that you don't want visitors people will mostly stay away....but then you can't go asking for help when you need it.
Walking around armed is a sure fire way to attract the wrong kind of attention, ever heard of "the gray man". Everyone knows he's there but ignore him as he's not attracting attention.
Hope this helps somewhat.
