How to connect a bnc connector to RG59 Siamese coax cable

In this video I’ll demonstrate how to attach
a BNC connector to Rg59 coax cable for use of CCTV camera applications. Let’s get started.
On our bench we have all the supplies that will be used. First we have a piece of Rg59
Siamese coax cable. This is an industry standard cable used in CCTV camera installations. This
is a compression type F connector. This is an F to BNC male connector. This is a Tl33
coax compression tool. This is a Tl22 cable stripper. And last, this is just a standard
wire cutter. First step is to use our cable stripper to
strip the coax cable properly. Place the Rg59 in the Tl22 cable stripper so that around
an inch is sticking out beyond the tool. Then rotate the cable stripper around the cable
5 to 10 times until you no longer hear the tool cutting. The Tl22 actually makes 2 different
cuts in the cable. A deeper cut is made to strip away all layers of the cable so that
only the core is left. You want to make sure the deeper blade did not cut into the core,
which will make it weaken. You also want to make sure none of the copper braided cable
is left touching the core. The second cut only removes the outer layer of plastic jacket.
You want to be sure that all of the braided copper is left in place and not cut.
Once the cable is stripped properly we must peel back the braided copper shielding. This
is important. Do not cut or remove the copper braiding. It is important to properly ground
the cable. Check again to confirm that no shielding cable is left touching the cord
coax. Next take the compression F connector and place it on the cable. You need to be
sure the connector is placed all the way on the cable so that the white insulator comes
slightly through the hole in the connector. Sometimes it takes a little twisting to make
sure the connector is seeded all the way on the cable. There we can see the insulator.
Next trim the exposed core so it is even with the end of the connector. Then grab the Tl33
compression tool. Seat the connector on the tool making sure that the cable core goes
into the hole on the compression tool. Then just squeeze the tool.The F connector is now
firmly attached to the Rg59 cable. Last screw the BNC connector onto the F connector and
there it is. This is a very secure way to attach a BNC
connector to Rg59 coax cable and probably the most favorite method among most professional
installers. CCTV Camera Pros supplies all the equipment
that was used in this video in an installation kit. We also sell each one individually. For

  1. How to connect a BNC connector to RG59 Siamese Cable

    RG59 Siamese cable is the industry standard coax cable for CCTV camera installations. RG59 Siamese can be used to conveniently run both the video (RG59 coax) and power cable 18/2 conductor power wire) from a CCTV camera to surveillance DVR.

    At the DVR side of the cable run, the 18/2 power cable typically connects to a power supply box and the RG59 is terminated with a male BNC connector so that it can plug into the one of the DVR's video input ports.

    There are a few ways to attach BNC connectors to RG59 coaxial. One of the preferred methods that professional installers use is to connect a compression type F-connector to the cable, then screw on a F connector to BNC male. The reason that this method is popular is because compression type F connectors are extremely secure and easier to attach than BNC compression connectors.

    This video demonstrates how to connect a BNC connector to RG59 using an male F compression connector and F female to male BNC converter.

  2. @Rui Pereira that is why a lot of professional and DIY installers like to use the F compression connectors. Being that the core is exposed on the F connector and the insulation is visible against the connector before you apply the compression, the process is easier. With BNC compression connectors, if you do not get the length of your cut and the exposed core right, the connector will not attach and it is hard to judge the length because everything is concealed. Another option that is easier that BNC compression is BNC crimp-on. You can watch a video on how to attach BNC crimp-on connectors here: How to Connect BNC Crimp-on Connectors to RG59 Coaxial Cable 

  3. Good video, however I have a different problem.I pulled the wires out of the end where the camera wires splits and have that thing that I guess separates them where you connect them to the long wires, I hope you know what I'm talking about
    The wire pulled off the video connector end, is it possible to go into the camera part take out that wire and replace the whole connector wire? Online the cheapest camera for my Samsung cost. $49.00 I installed (3 myself) it's brand new the whole I drilled was not large enough and I ended up pulling the end off one camera I hope I don't have to buy a whole new camera, Can you help me thanks so much.

  4. Hi. I have a problem what is the best way on the rg59 power cable to strip back the hard plastic on then power side .i can strip back the black out insulation ok but when i attempt the negative or positive wire. Both my automatic wire strippers wont even touch it.they just slide off. Thanks in advance regards james

  5. Your BNC connector have white part around the needle. As I understood from googling that indicates that it's working on 50ohm. However cables and DVR working on 75ohm. Only the connectors without the white part are 75ohm. Correct me if I'm wrong.
