security camera cable repair

Hi. I've lurked on this forum for years (since 2000) and usually always find what I'm looking for -- until now. I've searched for days - not just here but on the net in general - and either I'm not using the right search terms or I have stumbled upon something that no man today ever thought possible.... a piece of information that can't be found on the world wide web.

I would like to know if anyone can tell me which wires go to which wires in the following setup:

Security camera - cable has 4 wires - 2 yellow, 1 white, 1 blue
has standard telephone jack connector thingy at the end of its cable to which the long cable running from the monitor plugs into

Long cable - 4 wires - 1 black, 1 red, 1 green, 1 yellow
one end has RCA style plug that goes into back of monitor and the other end has an RJ-11 (or is it RJ-14?) modular plug that plugs into the camera's little jack connector thing

The story:
The long cable was severed at the plug. My neighbor, Einstein, insisted it would be easier to just hardwire the 2 cables (the camera cable and the long cable) together. After cutting the phone jack connector thing off the end of the camera's cable he saw that the 2 sets of wires didn't have all the same colors and wasn't sure how to proceed from there. Great. So another neighbor gives me an extra camera just like the one Einstein ruined but no cable. No problem - I want to keep my existing long cable anyway (for obvious reasons) but that leaves me with repairing the damaged end. I have the tools necessary and even know how to do it (I've made a few network cables) I just don't know which wires go where. I've posted a picture of both cables here:

I'm game for either hardwiring the old camera (worked fine until Albert cut the connector thing off) to the long cable or using the new camera and repairing the long cable, whichever is better.

I really appreciate any help offered.

Is there still some wire attached to the connectors? If so, use a continuity tester and test each wire to determine which terminal it is attached to. The using this info, you can figure out what wire needs to be spliced to which wire to hardwire them together or in which order the need to be installed in the jack or plug.


If this doesn't make sense, I misunderstood you situation. I would need more info or clarification for me to make sense of it. Others may catch on as is.

I don't have the connector jack thing that came of off the original camera. The links below are pictures of the camera that my friend gave me. The original camera is just like it, only it doesn't have the little plastic box on the end anymore. The cable coming from the monitor has a plug on the end of it that looks like a regular telephone cord and it plugs into that little plastic box on the camera cable.

I apologize if I'm confusing you even more --- hopefully the pictures will help.

If you had retained the original connector, this would be easy. These cameras that use the RJ type connectors are propriatory, so there is no standard configuration. The manufacturer's website might have the configuration layout.

First off, I really appreciate you guys responding to my posts and trying to help.

I found the original connector. Quite by accident - I thought it was long gone. As for the manufacturer, there is nothing printed on the connector. The camera wasn't very expensive and the box was kind of generic looking from what I can remember. I think it had IP64 on it big letters or something.

I would just go buy another one somewhere but I'm trying to avoid having to run a new cable from the monitor to the camera. It was a pain in the butt routing it through floors, ceilings, outside the house, etc. I just want to repair the old cable I have so I can use the new camera that my friend gave me. That or hardwire the old camera to the old cable.

If anyone needs to see the old connector, I will be happy to post a picture. Just let me know.

You should be able to look at the original connector, and see what wires were connected to which. Basically, two will be power, and two will be signal. Ususlly, signal will be on the two inner connections, and power on the outer pair.

ok, so i need to crack open the little plastic case? because I can't see which contact each wire actually goes to from the outside.

Just to be clear - I have the end of the old camera's cable - the part that the long cable's modular phone plug looking thing plugs into -- not the modular plug that came off of the long cable I want to repair. Does that make sense?

I'm still not sure I'll be able to figure out how to line up the long cable's wires in the new plug because they are black, yellow, red and green. (the camera's wires are 2 yellow, 1 blue and 1 white)

Thanks again for your help -- it is greatly appreciated.

i cracked open the plastic case and took a couple of pictures

Note: there should be 4 wires sticking up but one stayed inside the little plastic box

Now that I see where the camera's wires go, how do I determine where to put the black, red, yellow and green wires inside the plug before I crimp it?

Again -- THANK YOU SO MUCH for helping me out with this.

one more thing:

I just realized that I had indicated the camera had 2 yellow wires when in fact one of those yellow's used to be red -- apparently the red one had faded and I didn't realize it until I cracked open the little plastic box

The simple way is to take a meter or a continuity tester and see which wire corresponds to which pin, then make the new one accordingly.
