security camera system

[PreciousMexpert]

This system is about 20 years old and I would like to assemble it and use it.

I don't where were the wires should go.
It uses ordinary wires and coaxial cables
If anyone can help that would be nice

The monitor might be the reciever as well. Get you a small length of coax cable and hook it to one of the camreas then connect it to the "video in" on the monitor, power up the monitor and see if you have a picture. That should be all there is too it. If it works then mount the camera where you want them and run your coax cable to them.

Thanks for you help Barren
Here is a new picture

I should have included the adapter
These 2 cameras were working as is with these equpimnets.
the swithc is for switching from one camera to the next


Here I have 2 questions
If you look at the green lines that I drew is that correct

How can I run the ordiary wires so that I can attach it to the adatper
If it was 1 camera I would just conncet it directly to the adapter but what do I do
when there are 2 cameras

 

[Barren Realms 007]

Where you have the green wire's connected is correct. The regular wire's are know as twisted pair. If you can run coax cable I would use that because you will get a better signal than with twisted pair cable. Coax cable is easy to run and there is less of a chance or damage to the wire.

If it were only on camera I think this is how it would be
With this camera and adapter there is no place for a twisted pair cables
only 2 wires like those used on usual home appliances

What i would like to know is a way to connect the 2 cameras to that adapter
Thanks

You can set up a security camera system with an old computer
and a webcam,or upgrade camera.

There are some good videos on youtube that show how to set up zoneminder.

Hi jimdoc
That is something I am interested in but I could not find it on that site
would you know where the links are

 

[Barren Realms 007]

Twisted pair wire connection would be similar to wire for home appliance but it is smaller wire and generaly it is a shielded cable to prevent interference. On the adapter with the 2 wire's coming from the camera what type of connection is leaving the adapter? Is it coax cable or two screws for twisted pair wire? I am not sure if there is an adapter to go from twisted pair to coax cable. But there should be something available. If you can take pictures of the back of the equipment where the connections are and send it to me in an email I might get a better idea. If you want to do that let me know and I will get you my email in a PM.

I had it partially hooked up on a computer that crashed.
Next I plan on setting up an old computer just for zoneminder.

Hi Barren
For now I dont have pictures but I will try to get some
I am not sure but behind the adapter there is a place for 2 wires
the kind for ordinary type like I said and I dont think anything else would work
But I can check later on
But I know for sure that behind the camera there are 2 screws for ordinary wires and
I have the wires from the original set up
something like this

very ordinary
Thanks

Hi Jim I appreciate your help
It seems like there are other type of choices

That will be fine just let me know when you get ready.

Barren take a look at the blue lines do you think the 2 cameras will work if I did it like that

 

[Barren Realms 007]

No I don't, I feel you will get interference and crossed signals.

I feel you will get interference and crossed signals.

He shouldn't since most coax is shielded.And if that is an actual security monitor,there should have more than one video input,if it only has one,then you should find the input-controller that goes with it,then you can monitor/record both cameras at once,and potentially more.

I think what PreciousMexpert's question pertains to is the power supply adapter connections.

They should be in parallel. That is, the same terminal on camera 1 and camera 2 should both go to one terminal on the power supply adapter, and the same opposite terminal on each camers should go to the other terminal on the power supply.

If the terminals are marked + and -, then its a DC supply, and both + terminals on the cameras should be connected to the + terminal on the power supply. Same with the minus.

If it isn't marked for polarity, then it's probably AC. If it is AC, it might still have "hot" and "common" terminals, and at least the common should be marked "Com." Sometimes different color terminals or even screws are used.

So, if there is a difference between the terminals, keep them same to same.

If there is no difference in terminals or markings, then connect left screws on the cameras to left screw on the power supply, and rights to right.

If it smokes when you plug it all in---unplug it quick (duh!) 8)

Ahh I understand......in that case ,emphatically NO it won't work.You can not install a power supply to 2 cameras in series.The way you have the picture drawn,the blue wires would be the power supply wires,however you have them drawn in a series configuration which will double the impedence(resistence) whereas the voltage will be split between the devices,they must be wired in parallel for both devices to recieve the appropriate voltage.

What you say makes sense
These equipments and the this set up was working before it was taken apart so it should work again
There was always a problem with the system
In the monitor the images of objects were very faint and you could hardly see them
For example if there was a person in the image it was very faint
I wonder if anyone can say why.
but for connecting the 2 wires to the adapter should be something simple I will try your suggestions
Thanks

Not sure if you can see my replies but I think it could be condensation from having sat so many years.Could also have been the tube in the crt.

I plugged in the wires as you see it here and the lights didn't go on I didn't plug in the coaxial cables and I didn't see any pluses or minuses near the wires
Thanks

PreciousMexpert---

The blue lines are still in series, like mic mentioned.

Both blue lines on each camera need to go to the power supply adaptor.
