CCTV noob

Recently got a Samsung "home security" bundle that includes a monitor, a "video processor", 4 cameras, and 60 ft cables refered to as "rj11e" with 6P6C rj11-size plugs. The cables carry video, audio, and power to the cameras (12V DC). The monitor connects to the concentrator with a UTP-like cable with rj45-size modular plugs. Wish I knew more.

What exactly is rj11e? Is it a standard scheme in home security? Is the cable UTP? The documentation says it's "shielded". Do they mean as in STP? What are the distance limitations? Could I extend it/adapt it to the UTP wiring and jacks already installed in the house?

Sorry about all the questions, this has picked my interest. Any info, or relevant links would be much appreciated.

How about just looking at the plugs to see how they are wired and the cable? "rj11e" really isn't going to tell you anything, I don't believe there was any such thing.

If you plan on extending them might as well chop one up now to see what it is.

Looks like a regular coupler to me.

Other items talk about a "cable to Samsung connector" ????

Quite a bit when you google....

Well, like I said you have the cable to examine. You should at least be able to ring it out to see how the plugs are wired if you can't tell by looking.

Thats a 6P6C plug that is used by the telecom industry as a RJ11/RJ14 connector. Some Samsung CG has reused the terminology for their video cable but it is no more of an RJ11 then a 8P8C is a RJ45. You will find that is STP cable and almost impossible to make your own.

If it was built after 1980 don't expect it to work right.

I did try to google RJ11E and came up with very little useful material, most of it was dealers selling rj11e items. Couldn't find any useful documentation. The slim manual for the system gives the following pinout for the rj11e camera jack:

pin#
1 speaker (hot)
2 video out
3 ground
4 speaker (cold)
5 audio out/alarm out
6 12V DC

The pinout makes some sense if they follow the rj25 wiring guidelines. Notice that the outgoing signals are on the same pair (pair #2) and the "hot" leads are also on the same pair (pair #3). It would also make sense to have the gnd and cold speaker leads on the same pair (#1). It would be nice if somebody would just come out and explain. I've emailed Samsung tech support, let's see.

I had a security system like that once - it probably is one pair for video, one pair for audio, and one pair for power.

Forget the reference to anything RJ. There are no pairs, betcha it isn't even a twisted pair cable. Don't know why you are bothering with Samsung tech support. All they are going to tell you is to use that coupler and another of their cables.
