Install a camera outside front door of two story house

[Mase 0]

 

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.

I think you may be pushing poo uphill with a stick. It will all depend on the construction of the house which is a bit difficult to see. It appears to be cavity brick or brick veneer construction so there will be a cavity between inner & outer walls. The trouble you've got is can it be utilised. The house would appear to be on a slab so no underfloor access. There appears to be windows on the 2nd level above the front door so the cavity will be blocked there as well.
