Hello everyone, Matt from satscure.uk here
again. Today I’m going to do a quick video to show you how to make your own CCTV cable.
A lot of cable that you can buy is called pre-terminated cable.
You’ve got a video and a power, and the other end looks like this. Video and power again,
except the power is female on the other end. It’s always best to make your own cable, and
buy a big reel which has better quality copper in that kind of cable. You can see
it’s so thin, and usually the thickness of the cable dictates the quality, and how long
a run you can make using that cable. We usually sell this in 18m reels which works for 2 megapixel cameras,
but it’s always better to make your own cable! So cable on a reel usually looks like this,
so it’s a twin cable, it’s a lot thicker. If you look at the ends here you have one
that’s the power end, and one that’s the video end. The video end is just coax cable. This
cable is called RG59 cable + 2 Core, it’s a bit of a long winded name, but the RG59
part is this part which is for video, and the 2 core part is this bit because its got
2 cores in it! So what you’re going to need is a BNC crimp
tool which look like these, you can usually pick these up for around 20 pounds. These
are an optional extra, this is a coax cable stripper. You can use this for stripping the
shielding off coax cable, or RG59 cable as we are using in this video. You’re going to
need DC male and DC female power ends, which are the power ends for the CCTV. You are also
going to need BNC Crimp connectors which look like this. There’s 3 parts to these. There
are some small parts in them, especially this little bit here. You will have to be careful
not to lose those because they do go walkabout quite easily!
Ill clear the surface and well get started. The first thing we need to do is split the
cable. A lot of the cable that you buy comes like this so you are going to have to pull
it apart to separate the two ends. You want to grab your BNC cable stripper, and it’s
got two ends. This end is quite a lot thinner than this end. So you want to grab the thicker
end first, and you want to score the cable very lightly probably around 2 centimetres
and pull this off, which usually comes off with a little bit of pressure.
So we’ve got here are what a lot of installers call “Short & Curlys”. What we want to do
with those is twist them down and twist them back to the very bottom of the cable so you’ve
got something that looks like this. Then what you want to do is grab a set of
pliers and cut these end bits off quite short and cut them off so you are left with something
that looks like that. Then you want to grab your BNC cable stripper again and go about
5 mil down or at least half way down and cut this bit off so you have something that looks
like that now. Then you want to grab your BNC crimp connector.
Inside a BNC crimp connector we have this bit which is the main connector part, we’ve
got one of these little things which is the bit that you crimp, and we’ve got this tiny
little thing here which is the main connector that connects all the video footage to your
DVR. This bit goes on the end of here, and then you grab your BNC crimp tool.
If you look on your BNC crimp tool you’ve got loads of types of crimp for different
cable types. The one I use mainly is this type here, but here’s a tiny little one which
is used for crimping this tiny little thing onto the cable itself. So I’m just going to
crimp that on… What I also like to do is grab the end and
crimp that right on there. So now that thing is not coming off.
Next thing we want to do is grab our circular bit and slide that over the top of the bit
that we just cut down. This bit then goes on the end, push it right down and you should
hear it CLICK. The connector has just come straight through.
We grab our crimp tool again, this is the final time we will need to use it and just
crimp that onto there and just push it until its really tight. Might want to do it a couple
of times to make sure its properly on. And you should come out of that with a pretty
neat looking connection. That is not coming off now. And that is how
you crimp a BNC connector onto RG59 cable. Next bit we want to do is the 2 core power
cable. Use the cable stripper again, and you can use a Stanley knife if you don’t have
one of these. You can get these for about a fiver but they do come in very useful and
they do last a long time. Similar to what we did last time, you want
to score very lightly around the cable, so now we have a positive and a negative. We
want to expose the copper on the end so I’m going to use the thinner end now.
Positive negative – reddy possy, blacky neggy on the end of our power cable. And now we
want to grab our DC Jack, I’m going to use a male jack for this demonstration. If you
look at the male and female DC jacks they have positive and negative on them, so following
the reddy possy blacky neggy rule which I live my life by we want to stick those into
here and push them right in. So now we have something that looks like that.
Now we grab a tiny little screwdriver and tighten those up.
So now we’ve got a cable that looks like this. And that’s how to crimp a BNC Connector and
make CCTV cable! Thanks a lot guys!
