Lose WiFi in winter

We've been frustrated with the original camera with weather sleeves (as when we purchased, the outdoor camera was not available) because every time it gets very cold , the camera disconnects from the WiFi.  I understand this happens, but I need the camera high enough to see anything and prevent theft of the camera, which means that I need to climb the ladder to take them down physically reset them.  Therefore a good chunk of the year, the cameras are useless. Plus, I need to contact my ISP to allow me access to the 2 G WiFi network and only have one hour to get them down, reset them , and get them placed again. Is there a way to not have to climb the ladder every time they go offline?
