Nice; I've been using shielded video cables with BNC connectors directly from DVR to cameras so far

Coax is nice, At least you don't have cross-talk to deal with.

The only problem with using wire, Is lightning protection.

Sometimes Wireless pays off just because of the Electrical Isolation that you get.

Fiber also works great, You can't get much more Isolated than that. No ground loops to deal with either.

Fiber should get cheaper, I look for more Fiber Optic stuff to be available at a reasonable price.

Right now the twisted pair using Cat cable seems to be the choice for Video Security Systems.

Looks great, but why the power hookup? Do I need that power just for sending color video? And if yes, what transformer would work with that?

You only need the power if your camera is located away from a usable power source.

Or you could use it for Battery Backup Power.

The audio is RCA connectors and the Video is BNC.

You may need BNC to RCA adapters if your video camera is RCA.

Thanks, which do I need, the male or female BNC to Rca adapter?

http://www.homesecuritystore.com/nsearch.aspx?keywords=bnc to rca connector

Whats with the BNC? Why cant I find a balun with rca inlets?

And finally, I hope, whats the dif in cat5 and cat6 cable? they seem to be about the same cost; , are they interchangeable with simply higher speeds on the 6?
I knew the CAT 6 was for higher sppeds like for my Gigabit router and LAN cards, but honestly, I did not know the difference in construction, so here is the answer: it has a longitudinal seperator as described here:

You will need one of each of those connectors.

The BNC is a 75 ohm connection.
Make sure your that your camera is 75 ohm or close.

Normally Cat6 uses a slightly larger copper conductor.

I would use Cat5e or Cat6, whatever you can get the best deal on, With connectors installed, unless you have a RJ45 Crimp tool.

Thanks - The camera is a 6 year old pinhole type so I have no idea of its ohm rating.

Anyone hear of a balun with rca leads? Do the new cameras only use the BNC?

I think the first set was cheaper. You have to buy 2 of them, The other was a pair.

Video is nothing more than an AC Signal with Various Frequencies,
So You only need 2 wires (1 twisted pair). Leaves you more conductors for other things.

You can power LEDs. IR lighting works best with B&W cameras.
