I have purchased some Swann security cameras, and one of the places that I would like to place a security camera is at the front door area. However my question is how would I route the cabling seeing as to how this is a two story house, and I don't want to run the cable in front of the house up to the attic. The DVR will be placed upstairs. I have provided a pic of the house, I know it's hard to see with all the trees, but you can see what I'm dealing with and the front door area.
