CCTV/Data over wire
Dave Jackson
same wire for both CCTV video and network lan.
Is there a common cable that would satisfy both requirements? CAT5?
If I don't need to, I would rather not install 2 different cables.
Thanks in advance,
Dave Jackson

Thanks for you input, I think I'll just put in both cables then...
Cheers,

I'm looking at CCTV systems at the moment as well. I was looking at X10
based ones but I keep hearing bad things about them?
All I need probably are two cameras that will activate with movement or sound
and then feed to a PC that will do things (like page me or ftp the pictures
to a remote site) on activity.
I'm finding the different manufacturers/resellers sites a bit confusing about
what works with what etc.
If I put something like a vigilantern at the front and a basic PIR activated
wired camera at the back and feed them into one of those USB convertors
(http://www.cyberselect.co.uk/HomeAutomation/Products/USBInterface.html),
either both in via a single receiver (which will then rotate through the
inputs automatically right?) or separately into two USB ports - will that do
the job? Or are these USB adaptors only for X10 cameras?

You might not need a PIR if you use this software.

I actually have a CCTV system already
http://www.henrys.demon.co.uk/cctv/multicam.htm and I am very pleased with
if after 2 years, the only thing is that I want to add more cameras - hence
my posting.
The system I have is not cheap, but is good quality and can do all you want
to do and more.
I personally would not go down the X10 route for CCTV and would prefer to
keep it quite separate.
As far as triggering based on sound is concerned, it's a waste of time if
the camera is positioned somewhere other than in a quiet room in the house.
I have microphones on my external cameras and the wind/traffic etc just
makes it impossible to set a decent threshold.
As far as paging you when movement is detected, I think this also is not as
useful as it may first seem. The amount of times that animals have triggered
my system.... Okay, I can decrease the sensitivity to stop cats setting it
off, but I miss something else.
Although my system can do things like page, email, phone me - I don't make
use of these - I find the X10 pirs that I use probaby more reliable in
detecting unwanted guests.
Typically, it really depends on how much you want to pay.
Anyway, these are only my thoughts based on my experience.

InControl from www.digital-cybermasters.co.uk is worth a look!

to run coax - you have to be a little more careful, but RG6 is
inexpensive and a lot better medium for a number of reasons:
1. The wire is inexpensive and eliminates the use of:
A. Baluns (expensive)
B. Cameras with video capture cards.
2. The video can be used to feed modulators which will then feed
to all tvs throughout the house.
3. Even if you convert baseband video to IP packets, you will
almost certainly need another cable for it and a lot of ancillary
equipment (= expense and maintenance).
4. The equipment necessary to run RG 6 is actually cheaper than
what one needs for cat 5.
I'm in the middle of a fairly large residential job now. When
complete, there will be 6 - 8 cameras. I'm using Pelco and other
cameras, Pelco-Genex multiplexors, a 4 x 16 Pelco matrixer, and
feeding video to a bunch of Pico modulators, amps, and bandpass
filters into combiners and distribution. I'm using VTR's instead of
digital as they are half or less the price. A VTR has about a 2000
hour life before maintenance and a total life of about twice that.
For the 1/2 mile road we're using Cartels to avoid tripping by animals
along with some specialized equipment to detect people.
The analog technology has been around a (relatively) long time and is
pretty reliable. In my judgement, you get a lot more bang for the
buck.
YMMV

for camera feeds. I have a couple of cameras for my house and the last one
didn't come with wire so I just ran cat5 and it worked fine. It's only about
a 50 ft run and terminates back to a video modulator which I use to
broadcast over my cable TV. I haven't seen any ill effects from this.

ChannelPlus makes cameras with modulators. They're called CAT-CAMs. The
most common implementation for these is with the modulator remote from the
camera -- usually in the wiring closet. The connection between camera and
modulator is CAT5 (hance the name CAT-CAM). It's not a "network" camera in
the sense that it is not viewable over one's LAN. But if the real need
happens to be for a means of geting video from A to B over CAT5, they work
fine. Picture quality is very good. Also, ChannelPlus has a good
reputation for quality and for reliable customer service.
Disclosure: I'm not entirely unbiased about this since I sell ChannelPlus.

Try it and see! I use cat5 for a couple of cctv runs, and some
short (<10m) S-Video runs. There's a bit of noise on the CCTV,
but not enough to bother me.
Ideally, run co-ax for video, and certainly if you are installing
new cable, it would be daft not to put in the right stuff for
the job, but if there's a run there with spare cat5, give it a
try, it shouldn't hurt anything!
