You should not use Cat5 cable for alarm systems, its not designed for the
terminations and is prone to snapping off if you move it about a little.
Also BS 4737 has a specification for the cable type to be used, that's why
we have alarm cable. If you do use screened cable make sure you join the
screen at any joints and earth it at the panel otherwise it acts like a big
antenna to crap.

Does the homenet offer a high quality video distribution system like Kat5
(www.kat5.tv) using Cat5? I was under the impression they just had an RF
distribution system (which IMO is a waste of time if you want good quality
and are serious about video everywhere). Cat5e can be used for sensors
although I used screened 8 core alarm cable as it's more flexible and
easier
to fit and was only slightly more expensive than other cables.



I have a pretty full and complex HA/Alarm system comprising:



Comfort with second slave enclosure

2 x UCM's

Smartfit heating system with Smartfit UCM

At least one PIR in every room (something like 18 rooms/areas)

Glass break sensors

Cat5e absolutely everywhere (about 4Km ish)

Extron video matrix switcher (composite and stereo)

Whole-house audio

Whole-house microphone system (for voice recognition when the software
finally gets better!)

Various video sources including Sky+ and Sky (freeview)

Wired networking, wireless etc

5 CCTV cameras

something like 16 Kat5 units (including RGB for the plasma)

Motion detection system running under Linux

HomeVision HA controller

Lots of HA software running on server

40 X10 LD11's + AD10's in 3 54way enclosures for control of ALL lights in
the house

several phone lines distributed via Cat5e patch panels

The list goes on...



Don't underestimate the time it takes to retro fit wiring like Cat5e,
alarm,
audio etc - mine took me about 4-5 weeks solid (early mornings and late
nights) spread over several months - there was a lot though!



Cat5e faceplates - I looked around for a long time to find the right look -
in the end I just went with an MK design which was plain and OK - didn't
get
the best deal though although I bought rather a lot!



Heating - the Smartfit system is very good and links directly to Comfort. I
can control it via comfort, homevision, ACE or any other system I want as
it
all talks to each other (after a lot of playing and config!). Not the
cheapest solution though.



Lighting - I personally wouldn't go X10 for anything but lighting (as X10
lighting is cheaper than C-Bus etc) although if I was doing it again (next
house!), I'd definitely go for something like C-Bus for it's reliability of
signals and status reporting (big downside to X10) - is considerably more
though. I have quite a big house and do have several X10 'dead spots' that
I've never been able to fix. I recently connected the X10 transmitter
directly into the X10 enclosures and now it's super reliable :-)



I've probably spent around £20k for the infrastructure and Comfort/HA
controllers and that's with doing everything myself.



Don't know if that's helped at all - feel free to ask more...

Paul.

It is a new build ... but it is already built :-(

Basically I have bought a new flat, and plan to install cat5e and
ct100 throughout before moving in.  This isnt as bad as I first
thought.  The flat is all on one level, and the hall has a false
ceiling with a 2ft gap above - ideal for running cables from node
zero.  I've also managed to secure the services of the original
electrician who wired the flats.  Luckily he is familiar with
structured wiring as well.

I plan to also put in a Comfort control system.  Tricky bit is
working out exactly what wiring I will need for this!  I would like
to control at least the lights, heating, and hot water.  Plus there's
the security sensors to think off!

I am as yet undecided about the Sky+ distribution.  Its either the
Kat5 system, or perhaps IP Homenet.  I like the look of the IP
Homenet since its provides a neat all-in-one (well, almost) solution -
video, data, phone etc.  It is expensive, but it is available now.

Also planned for node zero are a Cisco 2600 ADSL router (since I work
for them ;-), and a Netgear fast-ethernet switch.  The Cisco 2600 is
too big for the IP Homenet rack, so I may get a small wallmounted one
>from

I am working to a pretty tight timescale for all this.  I move in on
8th august, and will only have one week to do the cabling.

Difficult bit just now is working out exactly which cables I will
need, and where to put them.  I'm still trying to understand how X10
works, and what is required to have it control the lights and
heating - wiring back to node zero?  new CH control panel?  New room
thermostats?

A few questions:

Anyone used videk.co.uk for cat5 stuff?

Can cat5e be used for PIR sensors?

Which type of cat5 wallplates are best?  Videk offer three types -
they seem to be of differing qualities.  Prices for a dual faceplate
(ex. VAT) are 5.95, 7.45, and 8.95

Anything else I should consider?

Thanks,
Ian
