Coax to phono connector wanted

Post by Guest »

I have a set of CCTV cameras that I want to test out on a TV
The cameras have a strange kind of coax fitting on them similar but not the same as a TV coax. With no way of posting a photo of it hear, things are very hard to explain, so I will do my best and hear is the model number of the camera Indigovision 2amp box camera BX620-HD-FC Dahua DH-PLZ1040D 2.7-12mm F1.6 VF Lence

The fitting on the TV for it to work (The coax port will not work) is a typical phono port

Any thoughts please?

According to

http://www.multiplize.net/indigovision/ ... t-A4_2.pdf

it uses a 75 ohm BNC connector.

I've used this adaptor

https://cpc.farnell.com/pro-signal/psg0 ... csku=false

with some of these cables

which have worked fine for both digital audio and video.

Connect to this

I mean I need it to have a cable and not just port to port.

On the

Yes, the adaptor has a female phono on one end and a male BNC on the other. When you combine it with the cable I linked to it gives you a BNC to phono cable. You can also buy those cables in a variety of different lengths if you want something longer or shorter.

Yes I know about the cable, I have quite a few of them laying round hear gathering dust, my local pound shop in the high street stock a vast majority of them as well. It was just that fitting that I am short on

Thanks!

For some reason its 10p cheaper then the gold coloured one

That would probably work - I suggested the others because they are ones that I've actually used.

Hah!! I read a little more of it and it actually says that it is gold plated! so for 10p more you get a small piece of gold trading at around £1500 per oz on the markets. Not to mention gold is a very good conductor or electricity which in this case will mean a better connection and hence a better signal

But sadly I went though the process to order it and they wanted an extra fiver for handling charges

Gold isn’t quite as good a conductor as many other metals, but it doesn’t corrode or oxidise in normal circumstances. So there’s a good case for using it where you have a permanent installation that will rarely be disturbed, and where your standard chrome-plated or even plain brass contacts will oxidise over time.

But gold is a soft metal, and will quite quickly wear away where you have connections that are constantly being made and broken. But this making and breaking action will normally remove corrosion through physical wear on chrome, steel, copper etc. contacts. Once the gold plating has worn away, it normally leaves a surface that's far more prone to corrosion/oxidation.

So, gold plating is not always the best choice for connectors, but it’s rarely a bad choice.

Reliably fallible.

About 20-25 years ago, before HDMI came along, as a not-using-fully-pro-gear camera person and video-mixer, I used the adapters as highlighted by James P all the time when needing to interconnect bits of kit. Always reliable and never failed.

If you don't like CPC's handling charges, then you'll find similar on eBay and Amazon. But in many years dealing with CPC I've always found them good value and very customer-focussed on the very rare occasions that things go awry.

I also find that CPC generally stock good quality
reliable components, where it's a bit more hit and miss on ebay and amazon.
