I've purchased a POE NVR home surveillance system with 4 cameras.

Going to run the wiring from each camera under my vinyl siding and into the garage. Going to drill a hole from my bonus room which is directly above the garage down into my garage and pull the wires to the NVR.

Figure I will drill directly through the carpet in the bonus room and then use a rubber grommet on both holes.

Are there any cons to this type of wiring or pitfalls I should be aware of? Having never done this before I am slightly apprehensive but it seems pretty straight forward to me.

Thanks in advance

 

Drilling thru the carpet can sometimes be disastrous.

Usually the carpet is held down with a tackless strip around the edge. It would be better to try and peel up a corner of the rug and then drill your hole then push the rug back down. Cut a small slot in the rug if the cables won't allow the rug back down.

I'm always hesitant when I drill into a blind area. What I do when I pass thru the floor in closets.... I'll use a 3/16"-1/4" x 18" long feeler bit to drill thru the floor and out the ceiling below. Then I'll drill the proper size, just thru the floor, for the cables. Below the floor where the bit comes out should be sheetrock and you can just enlarge that as needed.

 

I agree that it's a bad idea to drill through carpet. Often the fibers catch on the bit and it ends up unraveling and creates a run. You can cut the carpet with a box cutter or other sharp knife and then drill through the subfloor.

There are wire pulling drill bits that might help. They are available in different lengths but mine is about 4' long. It has a 3/4" sprial drill on one end and then a really long flexible shaft so you can bend the drill. The very tip of the drill bit has a hole so after you drill through a floor or wall cavity you leave the drill in place. Attach the wire or a pull cord to the tip of the drill so when you pull the bit out you also pull the wire or cord through the holes just drilled.

 

I think PJmax and Pilot Dane covered it pretty well. The only thing I might add is hole size and trim-out.

Once I've got a wire path from A-to-B, it seems I always come up with something else that "needs" a cable from A-to-B. Make your hole a little bigger than it needs to be.

At a electrical supply house or electrical section of a big box store (NOT the HVAC section), get a block, usually a pound, of what I call duct seal. Mold it around the cable in the hole in the floor to prevent air (and critter) infiltration. It's easily removed (and sometimes reuseable) when you run the next cable.

For the garage ceiling, get a single-gang low-voltage mounting bracket (sample picture below) and a single-gang Brush Plate for Audio/Visual (2nd picture). Install these before or as you pull the wire; they won't slide around the cables! They provide a finished appearance and access "for the next time". Personally, I'd use the same set up exiting the garage wall (inside only) and add some duct seal to the exterior hole under your siding.

Thanks everyone. Went very well. Used a box cutter to just reveal where I wanted to drill. Used a small bit to initially drill through before going to the 18" 1/2" bit. Am going to use either a door lock drill bit or a 1" spade bit to widen the entry and exit holes.

I've got a hole in the end of the 18" bit and I've also got fish tape so hopefully that part will be easy. Picked up a 1lb block of duct seal for the walls.

Have been limited in what I am able to do right now because of constant rain. Oh well, we can surely use the rain.

Thanks again

 

I was about to comment that you must be somewhere nearby when you commented about the rain. Sure enough... you are.
