Thanks for the correct wiring.

I had already made and installed wiring my way – just did not plug in the cameras as yet.

What is wrong with my way ?

Will it work with 2mp IP cameras or network switch (without POE) ?

Is there an easy fix at the network switch side if necessary ?

I am trying to avoid going up the lamp post to cut, re-pin and test aerial wires – it is a very big job

Its an industry standard. If someone comes in there and has to look at the wiring they should know what they are looking at without having to guess.  Not all switches are MDIX capable out of the box.  That is the feature that auto switches the color code inside the switch or router. If you have problems with your install the first thing I look at is the cable. Following the standards will make life easier for you  down the road.

The wiring convention is set up to use the advantage of twisted pair noise cancellation. If you use your method – it will work at reduced capacity because of crosstalk between the send and recieve lines. I am not 100% sure of why, but I have talked with installers who ran the same way you did – they were calling because their cameras kept dropping off line. As soon as he rewired his cables to 568B convention (see Arthur’s post above) – everything worked perfectly. So there IS a difference, especially over long runs.

Thanks for all the input.

There was no way around.

Had to rewire to the 568B standard (communication send and receive cannot be on the same pair and that is why blue and green are reversed)
