How to Crimp a BNC Connector & Make Your Own CCTV Cable. 

wow.

@@musicisdivineart ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NVIIKap9jYs.html is an example of how to do it _correctly_

He seems to have the wrong size connector for the cable also which is why he needa to do the crimping multiple times

@@tohtorizorro Correct. It's a RG58 (50 ohm) plug, not a RG59 (75 ohm) one It's important to note that putting a 50 ohm BNC plug into a 75 ohm BNC socket will effectively _destroy_ the socket centre pin as the pins are different sizes (75 ohm pins are about 3/4 the diameter of 50 ohm and a 50 ohm pin will catastrophically ruin the brass fingers of a 75 ohm socket by splaying them beyond elastic recovery limits, rendering them permanently intermittent) If this is an example of satsecure's professionalism, people should be avoiding his company like the plague

Hi Mate, do you know to do if im using a weaker (thinner) RG59 cable. All ferrules I've found seem to be for the thicker RG59 cables. I have already cut the BNCs off the runs as I had to fit them through 20mm conduits. Thanks

That is the worse crimp and install job ever. There are so many things wrong with the installation of BNC connector ever. The braiding should not be cut off as it part of the shielding of the cable. Canare has great crimp on connectors that I used in major telecommunications facilities that feed hundreds of thousands of customers.

Power drop over distance my mate. V=IR SHORT RUN FINE. LONG run tou get power drop. Cameras need electricity from flow

No, it's not "excellent", it's terrible. This is the correct way: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NVIIKap9jYs.html

As long as some of the copper mesh connects to the silver ferrel on the crimp it will provide grounding (i did leave some of it on the coax cable). The more copper mesh connected the better the grounding, and quality of picture. For longer cable runs its advisable to leave more copper mesh to connect to the silver ferrel.

Twisting the mesh into a twine and then crimping can crease the centre stinger by causing uneven pressure around the circumference and affect pic quality, bad technique in my view. Also multiple crimps on the collar is not such a good idea too; get a better pair of crimps that require only one application.

if you referring the 3 wires coming out of camera itself then it most probably means it has built-in microphone and if you are talking about the wire then it is used to attach ext mic.. *Red is +, Black is -, Blue or Yellow is Audio.

Just use the shrinkable tube to cover it. Shrinkable tubes are in different colours depending on the colours you want

Hi, you can buy the crimp tool here: satsecure.uk/rg59-crimping-tool-cctv-bnc-heavy-duty.html

If its a low voltage system you can guess which is which, it only has to contact for a moment, if you get no pic then flip the polarity of the wires and you have the correct pos/neg condition mate.

No problem :)

There are a couple of sizes of crimps that this tools is compatible with. Depends on cable thickness.

Thanks for response, after googling it seems I need RCA compression tool.

Of course :)

Why, it’s a poor crimp, and wrong way to do it
