We do not have a problem with "ne'er do wells", but do have many four legged visitors which want to eat the cat's food or the vegetable garden.
You may consider POE (power over ethernet) cameras which require, solely, an internet cable.
I have run 2 Zavio ones, which continuously stream to a Qnap server, for several years (there are several companies which do same)..
You will additionally require a poe switch.
This eliminates the need for wireless which, in my use case, is range limited and a power connection.
Batteries will not last long, without recharging, if you are streaming.
In my forest, I have two, battery operated, game cameras, with 4G sim cards, which detect motion and email me pictures.
They will also send smc messages but I don't use that option (expensive).
The biggest problem, as I see it, is adequate infrared lighting of the area to be covered.
You may need to invest in additional ir lighting as, over the years, the Zavio camera ir lights have aged and do not illuminate well.
