My home is undergoing a total renovation.  Right now you can see every stud, joist, and rafter in the home.

What kind of wires should I run to provide power and communication to security cameras in the future?

Cat 6. for IP cameras, and PoE for power.



Run extras, and run some to every room.



IMHO YMMV

fiber optic

 
Cat6 is what you want. PoE is something that runs over Cat6 though, so you just need 1 wire per camera.


However, as stated, run at least 4 to each room. Even if you only terminate 2, you can have 2 more in the jbox for future proofing.

Since it is so easy to do now, run a couple of cables to a chubby hole where you can locate a network disk,
which the dvr can copy to live ,in case the closet dvr is damaged or stolen during a break in.
Power to the chubby for a small ups is probably not a bad idea as well.

Id focus some effort on creating a chase from the attic to the basement or main floor. 10-15 years from now it might be a labor saver. If possible make some runs in conduit so you can replace them if need be.

I would suggest running pvc pipe in case you need to change wires it the future

This ^ in addition to the conduit/pvc suggestion are valuable. Sure, it will cost money, but it can be a HUGE money saver down the road if any re-wiring needs done.

Cat 5e & Cad 6 are "good" now, but then again, at the rate of technology improvement who knows when things could change and the wires in your home are considered obsolete.

run flex conduit, decide later when you have a system ready to go.

And label the conduit.

Run a 220 to the garage.

Might be a draft stop/fire stop code issue.  Check first.

Cat 6

I was going to say the same thing.  12 years ago when we built our custom home I ran all of the low voltage wiring (11K ft +...I know, overkill! but this is before wifi was really stable so lots of CAT5e for networking, voice, video cams plus audio/video and home automation too) and when first trying to plan out where to run it all, I asked the builder about a chase/pipe between the basement (home run location) and two floors above. He said it would never pass inspection, major fire code violation.  Acts like a chimney in a fire.

So I had to run everything up through wall spaces like the electrical guys had done. Each break in the floor and top plates of the walls had foam installed by the drywall guys once I was done.  You want to go last after the other trades so that you can avoid 110/220 lines and cross them at 90 degree angles where you must.  I used CAT5e and RG6 quad shield, it will support 1Gb speeds and was more forgiving & easy then to work with.  CAT6 was much more expensive then, esp the hardware (punch/patch panels, connectors).  That might have changed.

Fill it with fire stop, done.


Easy to dig out the fire stop, not easy to traverse two floors with cables.

1" or larger conduit. It sounds huge but if you end up needing to pull something with a connector on it you will appreciate it.

And if you terminate it in a box get the big ones for bending wires.

2 cat 6 wires
2 coax wires

In each room, including kitchen, dining, living, mudroom, workshop, etc.

Every single room. Don't skimp. You'll be cursing yourself later.

Run homeruns from a central point easily accessible for your cable/tv/internet provider
