So I just learned that not all borders are fenced, very few of them are actually. So how are countries able to monitor thousands of kilometers of unfenced borders to fight off smuggling and illegal immigration ? Especially when it comes to long borders in arid/undeveloped areas, one example that comes to mind are the borders in Siberia.

Most of Canada and the US border is unfenced and unguarded. Some times the border runs through small towns, so you have to cross the border to get to school or the grocery store.
Why? Because Canadians and Americans travel mostly freely between nations anyway and it’s not worth it. Socially speaking there’s not much difference.
The southern US border is a whole different story.
However, major roads between Canada and the US do have border control. Cars and trucks carrying trade goods are checked as well as people.
However 3000 km of forest don’t need fences.
