RJ45 ethernet connections

[ShinySideUp]

I am currently putting together a CCTV system with a POE NVR but I am so confused over the two protocols for wiring my cables. I've already done one and it works fine and I used the 568B standard. I know that if the connections are the same at both ends all the wires could be the same colour (if a little inconvenient) and it would still work but what is the definitive configuration for a home CCTV network. One site I looked at said:

"T568A is generally seen as the superior configuration as it offers wider backwards compatibility than other wiring schemes. However, T568B is more common, particularly in slightly older cables and equipment."

Not very helpful, and this seems to be the general form of information supplied everywhere; it's like no one wants to commit. Does it matter at all which configuration I use, no matter what I subsequently use a cable for in the future?

It will make no difference unless you want to put a new plug on and wire it the wrong way, so stick to one or the other.

Makes no difference. The only thing that changes is the colour of the wire.

Anybody telling you that one is superior to the other is talking out of their backsides.

If you haven't already got one of these, get one.

They come in many varieties and only cost a few pounds from Amazon or such like. Just plug the cable in at both ends and switch on. If all the lights match up, you know the wires are in the correct places and the circuit is unbroken...

Yes, I got one with the wiring kit I bought from Amazon, have used it already. I decided on 568B but only so I can remember the pinouts easily.

In the UK 568B is the standard you usually come across, in over ten years on various sites I think I have seen A once or twice but that is about it.

As long as it wired. if both sides are A or B type is a on to one eg. Pin 1 to pin 1 etc. Usually for a router . If one side is A and the other is B then it’s a crossover. You don’t have to follow any standard (but it’s recommended) as long as canle is the correct configuration

Go with 568B, done data cabling for many years and rarely come across 568A
