I just closed on a brand new house and the basement is unfinished. It is a 2 story house with unfinished basement. I want to have a wired security camera at the front door, at the side door, at the garage, at the kitchen patio door, and at the basement door. This is probably an easy question but should I just drill the holes from the outside in and then drop the cat5e cable to the basement at each location and then set up my security camera system that way?
