CCTV Cameras

[RandomGrinch]

As we have both said, they are definitely visibly different - so, in that sense, what you have is clearly 'wrong'. However, whether the one depicted in the TLC piccie would any better suit your purpose (in terms of connectors), I have no idea.

The one dipicted in TLC has twin (figure of eight) wires for the 12V DC output - far easier to strip and insert into the camera power connector, than trying to modify a coaxial cable.
That was the basis for my recommendation of it.

That's all fair enough, and I agree. At least in my experience, the (often tiny) conductors one finds after 'cutting the plug off' an ELV PSU (or suchlike) cable can be very difficult to deal with - but, as you imply, perhaps less so with 'figure-of-eight' ones (particularly if polarity-marked!) !

Not know if the input is DC or AC is still a gamble cutting the plug off thinking it is AC, we dont even know if the 12V is AC or DC yet, infact we dont even know which was round the input and out put wires are since as there are no instructions included with this

What is a figure of 8? is it something to do with a set of diodes wired together to force AC into DC or something?

You said earlier the input was 50Hz that is AC
The output is usually indicated by + and -, with " . " And a " ) " to indicate the pin and outer of the plug to denote the polarity.
If so the + and - denote DC output

That's all rather muddled. We know that the camera will accept either 12DC or 24V AC, and we also know that the power supply you ordered produced 12V DC -so one hope that what they sent you is the same. AS for input and output wires, the ones with the plug you illustrated will be the (hopefully 12V DC) output of the power supply, and the other one will be the 'mains input'.

That is a figure of 8? is it something to do with a set of diodes wired together to force AC into DC or something?

It's simply a description of the (visual) appearance of the cable - looking like two single insulated conductors 'stuck together' - so that if youu cut across it, what you see looks like a 'figure-of-eight' cross-section.

Figure of eight is just two single round wires moulded together in the middle by the insulation, looking end on will look like a 8

Probably easier to get an inline socket and make an adapter to bare ends rather than muck about with the rubbish wires you usually get in those power supplies.

I agree, for the reason we've both mentioned - those wires can be difficult to work with.

Well that is something that you learn everyday. Now thinking about it it kind of makes more sense as the Hz is a frequency wave that I guess if it where an alternating current then it would do this as opposed to a DC current which would not give off such a frequency wave

But there are no + and - on the device

 

[JohnW2]

What device? Your cameras have very clear + and - markings.

As for the power supply, the one you ordered from TLC had markings which clearly indicated that the 'inner' of the plug was + and the 'outer' was the - . Are there no similar markings on the one they supplied?

Even if you get the power supply sorted out, I still don't really understand how you are going to 'test' (let alone sell) the cameras if they have no lenses - do you perhaps have the lenses hidden away somewhere?

Right or wrong, I assumed it was part of a learning experience for the OP - nowt much wrong with that.

No there are no markings present

I have quite a few of there cameras some have the lenses some dont. Dont want to sell them, they are for a project later on

 

[JohnW2]

None at all? I think you need to be seriously asking TLC what on earth they have supplied!

Fair enough. I was going by the fact that you seemed to be concerned about whether they were "worth anything".
