Remote view/access camera

I Came across a camera in the bush recently where the fella had run an antenna wire up the tree its on.

Im assuming its one that he can view remotely or something, didnt want to mess with is to coudl not see make/model etc

Anyway, who uses these types of setups? id be keen to have a camera or 2 that I can log into and see what's going on without having to walk in and pull memory cards.

Any pros/cons, recommendations?

Id imagine you need 4g signal, the camera i found above was in a sport with little to no signal, but i guess thats why the antenna wire was up the tree

cameras transmit in the top of the uhf range around 800MHz longer antenna may give more capture area but unless it tuned right its worthless.
