if your going to caulk around the camera just make sure to bench test it well before deploying since doing so after the fact will be a PITA; might also make using internal SD a bit of a pain as the cards are known to flake out after a few weeks/months of operation if you cheap out.
but I agree, I prefer to flush mount cameras when possible.. but I dont mind the look of EMT Conduit when the alternative is cables strung along the outside of the house.. Mine is half Brick half Vinyl, on the brick side it was easiest and cleanest to use junction boxes up high, then black painted conduit down to ground level where I could drill directly into my basement.. its all on the sides and back of the house and my brick is black so nobody ever see's any of it.
Maybe I type it out wrong. Let me try to explain it differently.
I am not caulking the camera itself. I haven't install it yet and I never installed an turret "eyeball" camera before but from looking at the turret on my table, it in three pieces right? The back mount, camera and camera cover plate.
My thinking is that I will be drilling at least 3/4 to one inch holes to be able to run the Ethernet/power jack through the wall.
After drilling the hole, I would screw the back mount to the wall then that where I would do a half moon caulking. I would apply silicone only on the top half of that mount so rain water will run down around the back mount but if rain water somehow get inside the mount then it will drain out of the bottom since there no caulk there.
Then when I started to put the camera onto the back mount at same time feed the Ethernet/power cable into the hole, I would just screw the cover plate on it and adjust if necessary.
One thing that I thought about is I might use a rubber stopper with hole and slice to insert the cable and stop up the hole to further seal it up but I could always remove the stopper and pull the cable back out if I need to service the camera.
The camera itself seem to be sealed so no worries there, just need a way to prevent the rain water going into the hole where the cable is run through but I don't want to fill it up silicone after feeding cable into it. I would have to break the silicon seal and clean silicon off the cable every time I need to service the camera.
