Central Distribution – Completed

Today involved a lot of wires. Corrected one problem involving the telco system, relocated the entire television distribution system halfway across the basement and then relocated all the old wiring to the new location (thankfully I had left plenty of slack when I made the temporary arrangement) and then crimped, stripped and drilled like mad.

Central distribution point for both telco, CATV and SATV

The final product is pretty slick. All the stuff tucked nicely out of the way and next to main electrical service, everything in the house wired to the nines so I don’t really see much need for expansion (although we have some room for it with one extension for both the telephone and television unused).

I’m proud of the finished result, but I am glad it’s done.

I love it when a plan comes together…

Wiring completed, old extensions removed and am running the new distribution board as the only extension off the main drop. I am still seeing some problems with my DSL connection, but I’ve got a few ideas as to how I might clear that up, and I think we can safely say that if these problems still exist then they are located on their side of the demarc.

The good news is that the new extensions and wiring function perfectly, so I get to spend a little while pulling the old wires out and removing the surface mounted outlets.

Another consequence is that the wiring in the basement is becoming considerably less complicated.

Cool, huh?

Is it a compulsion? Yes I think it is…

Ok, so every room in the house has new wiring for telephone service, a working network connection and at least one (sometimes two) cable connections. These are handled in an organized fashion through their respective trademarked S.T.A.B.screwed to a board” (©Impact) distribution systems and there is some room for expansion.

I think we’re wired at this point.

I’ve gone a little over budget and I need to scale my activities back to projects where I already have the materials at hand. Next on the drawing board is the installation of the intercom system (acquired ages ago) and it’s accompanying video feed.

I’ll also be selling off my old hardware (primarily on ebay) so anyone looking for a reasonable deal on some analog CCD cameras, small monitors, PCI capture cards, multiplexer and switcher should drop me an email. I’ve got to clean out my basement and the funds will go to my alarm system project.

On a final note, do you think that all this cabling in the walls counts as insulation? It seems warmer in the house recently.

-GRIN-

Turning messy now… and still more to go…

Still waiting for little bits and bobs, but the wiring continues. I think I’ve done all I can before I actually start moving services, so things are likely to go downhill asthetically from this point forward.

The wiring is going to clutter up things a bit, no?

See?

Telco Progress

I’m almost at the point where I can move the main telco drop to the new distribution system, as soon as my RJ11 connectors and crimper arrive I can wire all the components together and see if things work. In the meantime I’m re-running all the telephone wire in the house and replacing it with Cat5.

new and improved telco distribution

For those that are even remotely curious things will work like this. Telephone service is fed through the DSL splitter and then into the telephone hub as two seperate lines (one data and one POTS (plain old telephone system) eliminating the need for those pesky DSL filters.

It should result in a cleaner signal for the DSL and it will certainly be less visually offensive than the original stuff.

Eventually we’ll have rewired the entire house..

I’m pretty sure I’ve mentioned once or twice that our house is somewhere around 100 years old. While a lot of work has already been done (both by previous owners and now by us) more remains.

Most recently I’ve been unable to stay connected on the Playstation network for any period longer than 10 minutes, these disconnects caused by the DSL modem reestablishing a link. Line noise is evident when talking on the phone, and it’s top of the suspect list for internet interuptions.

This is seriously impairing my ability to entertain myself with Fraternal zombie mayhem!

So, I wander down to the basement and look at the wiring. I look again, and I feel that sinking feeling in my stomach. There are a lot more wires than receptacles in the house (or at least those I’ve found), and I can’t easily identify the main service (what I thought was the main service turned out to be a grounding wire that goes outside the house and then nowhere – don’t ask, I’ll deal with that one another time).

Nice wiring, eh?

So, the newest project is twofold. I’m identifying and removing dead cable runs, re-wiring the main distribution point and while I’m getting dusty and irritated I thought I’d trace the old alarm system wiring while I was at it (like most alarm system pulls the techs just cut the wires at the alarm system end and then at each device. Tracing these wires would make the installation of my burglary system CONSIDERABLY easier).

So far two dead runs have been dealt with (Including a phone outlet mounted in a 4′ space between a basement wall and the side of the basement stairs.. so well hidden this is the first time I’ve seen it since we bought the house).

Stay tuned….

DVR Project – Early Implementation

My old DVR system was a normal PC Tower with a 15″ crt monitor and occupied WAY too much space, it also utilized RCA connectors instead of the more typical BNC connectors. The end result? Every time I had to do any work on the surveillance system I would end up making a mess of things (this is the primary reason I wanted a compact desktop PC for the second version) popping cables off their connectors, mixing wires up. There was A LOT OF CLUTTER.

A few weeks ago I experienced a problem with one of the cameras, intermitant signal loss. An irritating problem to diagnose, and one that caused the usual chaos when I started tampering with things. I got angry and despite the fact that the RAM had not yet arrived for the new DVR I decided it was time to pull the old one out.

A few hours of manhandling hardware in and out, some mucking around with the configuration, more grumbling and more mucking around and finally the entire system comes back online.

The computer specs represent a significant increase in power and storage;

Old System: 1.7Ghz Processor, 256Mg Ram, 40Gig HD
New System: Dual 2.8Ghz processors, 2.5Gig Ram, 500Gig HD

By way of storage the old system recorded 6 video feeds (5 camera feeds at 320×240 @ approx 2.5fps recording only motion and 1 feed from the multiplexer at 320×240 and 5fps recorded 24/7) and would keep the last 4 days of activity before automatically overwriting the oldest activity.

New system records 7 feeds (6 camera feeds at 640×480 @5fps recording motion, motion recorded at 20fps when detected and 1 feed from the multiplexer at 1280×1024 @ 5fps recorded 24/7), settings are still being fine tuned but at present 10 days of activity are kept before oldest events are overwritten.

Of course the switch to 640×480 has introduced some interlacing issues as these are analog cameras, and I may finally have to begin experimenting with IP cameras to get around this.

In the meantime I couldn’t be happier with the system. I still need to clean up the wiring quite a bit, but for now it’s adequate (if ugly).

Home media server?

Until recently I used an 8gig usb drive to walk movies and MP3s over to my PS3 from my computer. It’s an inexpensive arrangement ($20 for the USB drive), but its recently seemed like an extra step as my computer and my PS3 are both connected through my home network.

I did some late night reading on the PS3s “media server” stuff and installed Mediatomb on my desktop (Ubuntu) system. Right off the bat (with no special effort or tweaking) the PS3 “saw” the MediaTomb media server on the PC.

Accessing the files was not so easy, at first I got a “There are no titles” message. With just a little mucking around the PS3 eventually saw the files that had been indexed on the PC, but attempting to play them first resulted in a “data is corrupted” error and then (after some more tweaking) a “DLNA 2104 protocol error”.

This is where we stand for the time being. There is more tweaking to be done, I’ve come across a step-by-step guide for Gentoo which seems to have several PS3 specific suggestions, and I’ll be trying them one by one.

Anyone have any experience with this sort of thing? It occurs to me it’s one of those things that would be handy should it work, but could be a whole lot of headache for little result.
