Sounds like the old camera was a bullet / pencil style camera is this correct ?
I have a camera on side of building that is faulty,
can not acces the cabling, so did a chop of cable,
only 3 wires (white) (red) (earth)
new camera has for wires 2 for video, 2 for power.
so i joined the earth for video and earth from power. to the earth on the wall cabling, yellow from new cam to white wire ,and red to red.
but no go. any ideas ?
thank you.

have you measured voltage on the cable ?
Did you power down the camera supply b4 cutting/baring any of the cables ?
What votage does your new camera require ?
Did you test your new camera on the bench b4 trying to install outside ?
Does the camera specs you have match what is required for the installation ?
You don't give enough details to give any exact advise so you will need to go and check all of the basics first.
^^^^ what he said
i just had to replace some connections on one i have and it also had the 4 wires but the white one was for nothing it was actually not connected to anything on the cam itself.
so it was
red = power
black = ground
yellow = video
white = zip
When you say, yellow = video
Can you explain further ?
The cable that you are terminating on, is it RG59 and a seperate power cable?
If unsure, attach a photo!
No keith, If you actually pull a camera apart you wont find COAX rg59 or rg6, mate you will find tiny wires
Red is +
Black is common (ground)
Yellow is video and
white is Audio
you link the common (neg) and the sheild of the coax together and it will work
so yes YELLOW is video
Haven you ever looked at some rca leads mate???
Where did you go to alarm school???
Is the original cable coax & fig 8 or is it 4 core sheilded. Disconnect the internal end & identify what the power is on & what is going to the mon/recorder. It seems easy to me.
sorry not expaining myself,
the orginal cable is as you say coax plus fig8 but all i can access was the cable going into the old camera , i cut this expecting to see 4 wires but only 3 exisit, so the 1 x earth must be for the video and power.
new camera has as we expect 4 wires, my thing was to join the 2 x neg wires with the 1 x earth.
does not work.
opened old camera and the 3 wires go via a IC then back to 4 inside the camera.
so looks like i need to knock part of the brick work to get to the full cables after all.
Have you thought to test the cable your connecting to?
12v on power?
RG59 (coax) tested for an open/short circuit?
I asked that same question, i think Security Tech is the man to solve this one.
Clearly the alarm school i attended isnt to his standards :P
No point trying to solve the problem until we know exactly what type of cabling is in place.
What are your thoughts Security Tech ?
By the sound of it I think he may still go to school Keef
