Just run a bare length of burial grade cat 5 through a tiny hole and run it straight up into a junction box with a drip loop. One tiny small wire and it's waterproof. So, cam on the box, wire coming out pointed straight down, then in a bit of a J and up and then into the house under the eave. Angle the drill up so any rain that gets into the hole will drain back out instead of having a downhill run into your home. Seal the hole around the wire as well. Big waterproof conduit like hook3m used isn't really necessary although it does protect the wire from the elements (not necessary with burial grade wire) and tampering (IMHO not necessary in home installations). Why protect the wire if they can just rip off the cam, spraypaint the lens, or put on a ski mask? If the criminals know they're there in advance and determined to defeat them then they won't be much good for facial ID but they'll at least provide some evidence as to what was done.
