how to wire cctv into ac dc
Discussion
To save damaging the one that came with the camera, have you got an old charger with the same size plug?
I would cut the plug off with some lead spare, bare the wires and join them to the existing wiring (making sure you get them the correct way around, positive is normally the centre pin on those round plugs).

So you're using the old transformer at the head end and the old white alarm cabling? You've connected the pigtail via the chock block yes? pig tail via connector block yes
Have you got the polarity correct? yes ive wired hikvision as per same way that the old bosch camera was
What voltage is the old system, also 12v DC? 12v dc yes

yes they still work. What a fk up! My fault.
So if I buy a 12v dc to replace that im thinking all will be ok?
And what type of 12v supply should I get any recommendations

How many cameras do you have? What current do they need, what is the amp rating on the camera?
I suspect the existing power cabling is a parallel circuit running from camera to camera? You should be able to use this if you get a 12VDC PSU with the correct current/amp rating.
That PSU you have linked to requires an individual cable going to each camera, you could use the individual cores of the current cable but it will be a faff, better off getting a single PSU that can do the job.
What is the exact spec of the PSU that has been supplied with each camera?

A few pointers.
Ignore everyone who is telling you to cut the ends off any cables. You will immediately invalidate any warranties and you are likely to damage things. You've already tried to power a 12V DC camera with a 24V AC power supply. All the DC plugs, sockets and so on are available off the shelf with easy to use screw terminals.
The power supply you have linked to must be hard wired with a fused spur. It is not a DIY fit item particularly if you are fitting it at work. It needs to be fitted by a qualified electrician. Stick with a power supply which uses a normal mains plug.
In terms of the wiring you have there it really is anyone's guess. I suspect someone has used some form of data or telephone wire and doubled it up to avoid voltage drop. You need to investigate more.
The power supply you were going to put inside the camera isn't waterproof. You don't want to have mains voltage inside a camera enclosure if possible. The general idea is you fit the power supply inside the building possibly near the DVR and then run 12 volt power to the camera using the same cable which takes video back to the DVR (subject to cable type etc).

it's a 12v 1amp adapter . There are 6 camera's in total I suspect the existing power cabling is a parallel circuit running from camera to camera? You should be able to use this if you get a 12VDC PSU with the correct current/amp rating.

Yes i think the cable runs from camera to camera as there are 2 poles, each with 3 cameras on and the wiring going into the pole is 3 coax cables and 1 of these white power cables
