First off, your cabling doubles as your telephone wiring, so 2 per room is reasonable. Put a jack anywhere you think you may need a phone, computer, or media device (TV/Boxee/game console/etc). If you know you are going to likely need a couple at some particular spot (eg, a home office, or your main TV watching area) then you can do that as well. Run all ...

You have good answers so far, but I have several items that I don't think have been covered yet. I will start by recapping. Number of Cables per room Cat5e (and cat6) can be used for telephone, both the old school phone and VoIP phones. This makes it easier to not have to worry about running as many different types of cables. I would highly suggest going ...

Gigabit Ethernet If you need Gigabit Ethernet (1000Base-T), you're out of luck and will have to run new wires with CAT 5e or better cabling. It's likely not that difficult depending on your house. It seems like these jacks are above each other in the same place on each floor. Thus, you could easily drop a cable down from the upper floor and run them all ...

Before you spend too much time and money on this, buy a new wireless router. They've come a long way. When finishing my basement I added two communication drops to each room and...never used them. Wireless was fine. What's more important than the cable is that you have an easily accessible way to run what you need at a later date. Smurf tube is a common ...

It's not real critical. When wiring phone centers we used metal raceways (or a thrown-together wood one) in the ceiling, but for my house I used pipe clamps like the one you posted at about 4' spacing. I like to add a wrap of double-sided velcro around bundles going to the same box, also about every 4'. Near the demarcation point I might use a few screw-in ...

Fiber would be ideal, but... Bear in mind that terminating fiber is more exacting and more expensive. It requires special equipment and special skills. You can't just cut fiber with a pair of wire snips and crimp a plug on the end of it. The ends have to be angled and polished, and it sucks when you poke the little fibers in the ends of your fingers, etc. ...

What I have yet to find a solid answer on is what is typically run to the keypads. Do I run cat5/6, or use the same security wire (or both)? I recommend running 22/4 and cat5e from the security panel to the keypads. That provides lots of options. Once I run the wires to each window, where do I leave the wire? I recommend leaving a coil of wire in the ...

They are called "wire grommets" or "electrical bulkhead fittings", and if you search for those (or some combination of those words) you should find what you're after. I typically seal large exterior holes with expanding foam, and smaller holes with silicone caulk. I've run many cat5 and coax cables through walls, and generally keep the hole just slightly ...

Since you are in a one-family dwelling, there is really only one important article to be aware of. 800.26 Spread of Fire or Products of Combustion.

"No Volume Limit" Advantage of Open-back Boxes The open-backed boxes have the advantage that they don't limit the termination area's volume to the size of the box. Here are a few scenarios where having more volume than what a box provides is important: In the case where the structured cable will be run directly to a device in the room (think speakers), ...

Here's the caveat with old coaxial cable. If this is an older house, it might have cable already, but it's probably RG-59. This is from back in the days of analog signals, well before we were sending digital signals down them. If you have a satellite dish, you'll note they need RG-6 or better. What's the difference? Shielding Now, it's possible there's no ...

Yes, its still valid. Power and data cable coatings are insulation - designed to protect from electric shock and to avoid short circuits. They do not interfere with magnetic fields. I do not know what kind of shielding you are talking about - I have never seen any modern power or data cables with shielding that blocks magnetic fields. Magnetic fields are ...

This has been discussed many times on this site and maybe even a few times on Server Fault. Step 1: The plan Come up with a plan - how many drops per room? Where will you terminate all the wires back to? Are there clear path's from floor to floor via the walls? ie: is there an empty part of the wall on the first floor but not on the 2nd floor? Do interior ...

What about running it along the underside of that shelf that runs around the perimeter of the room? Just drill through the wall underneath the shelf and between some studs, and run the wire tucked under the shelf all the way back against the wall. You won't be able to see it unless you're sitting on the floor.

2 Cat5e drops to each bedroom. You can put them in the same faceplate; you can also put your coax cable for the tv / receiver in that panel also (including phone) - Leviton makes face plates that accept from 1 to 6 universal connections (this can be rj45, rj11, coax, etc...) You need a switch regardless to break out your modem (be it DSL, Fiber, cable modem)...

Note, I'm not anywhere near an alarm professional, however I have installed a couple systems before and have just recently been researching again as I prepare to move into a new house where I'd like to install an alarm. Keypads You'll want a keypad anywhere you normally enter/exit the house, such as by the garage door or back door. As @bib points out, you ...

No, not a bit. Twisted pair cables are HIGHLY resistant to interference pickup. Furthermore, DC does not cause interference, since it is basically an unchanging current, so there's no change in magnetic fields from it to cause interference (other than when turned on, and off - and the twisted pair cables will reject that interference by design, anyway.) I ...

This is what ENT (or any sort of conduit) is for If you want to leave "room for installing wires in the future" in an electrical installation, you put a conduit in the wall so that the installer who is doing the pulls can actually do the pull without getting wires damaged on edges and whatnot. For data wiring, electrical nonmetallic tubing (ENT) ("smurf ...

Wire is cheap, opening up walls later is expensive. I would lean towards running as much cable as you think you might need, even if it isn't terminated, and just coiled behind the wall, or in a junction box with a blank plate on it. Another tip, not just for cabling, is to take pictures of the pipes, wires, etc, before the walls are closed. This will be ...

Well, here I go potentially disagreeing with some more experienced folks. Assuming you have clearance over the ceiling all the way to the back wall, this is doable with fish tape and a hole in the wall with the tv on it. Get some small conduit (even thin pvc pipe will do), and put a 90 degree angle in the end. In the case of metal conduit you would bend it ...

TL;DR it should be OK to run them together. The signals from a security sensor are typically very low frequency because they're generated by the switch within the sensor opening and closing as the sensor activates. So for a motion detector, it might open and close a few times as you cross the field of view; a door or window sensor would switch as often as ...

The first step is to cut the cable to length. You can use any tool capable of cutting the cable, personally I reach for my trusty lineman pliers. Once you cut the cable, it will look something like this Now that the cable is the proper length, you'll have to strip the insulation off. Again, you can use any tool capable of stripping the insulation without ...

(Lots of) Home runs are good You are correct that you want to run a cable to each room from the central switch. In fact, I would run at least 1 more cable than you think you will need to each room, and consider running a line or 2 to other rooms as well - especially if your walls are open. Cable is cheap, and pulling 4 cables instead of 3 is no more work ...

Pin 6 is not crimped. Your crimp die is defective or you need to try again. All the pins should be at the same level. But really, punch-down into jacks and buy patch cables as already suggested. Cheaper and more reliable.

If you want to bury the cable directly in the ground then you need to use direct burial-grade cable and not "standard" cable, otherwise you need to use conduit. First you need to consider the distance to the poll. Depending on the distance and use of the cable, you might be able to use RG6, but you also might need to use RG11. You want to bury it deep ...

If you are at construction level I would most certainly advise you use PVC conduit to run multimedia cables. In Europe I have noticed that nobody bothers too much about that in home construction because it is an extra cost. In Africa we used them everywhere because they are a time saver! Why do I suggest using them? If you clip these cables using the clips ...

From this photo: Cable modem is likely attached to the cable at the lower right corner. Cable modem network jack goes to the internet port on your router. Lan ports on the router are connected to the patch panel in the center. The yellow cat5/6 wires are networking to the rooms. If you want TV's in different rooms, you can swap out which white cables are ...

First, don't use the wiring for anything else. It's a life safety system. Don't mess with things that are this critical. Second, the signaling is simple: voltage on the line means one of the detectors has detected something. To address your ideas: Anything but the cheapest detectors has an indicator light on the front that tells you which one has been ...

There's no substitute for it: You're going to have to fish that wire. A couple observations: 1. If you were the "cable guy" you'd probably take the easy way out: Drill from the living room through an exterior wall, then go up the outside of that wall. Pretty cheesy, but common enough that people pretty much accept it without much question. I'd ...
