Hi ,

 

I am installing some Hikvision cams and need to attach mikes to data input for Dahua nvr , i will splice in to cat 6 cables .

 

Can some body please advise which colours are applicable for this application.

 

Cheers Jacka

Are you using cameras with mic inputs or are you running mics back to nvr for a different application?

 

If you're running them back through spare pairs on the cat6 then on the cat6, you can use the blue,blue/white and brown, brown/white

 

This is as long as you are not using gigabit LAN.

POE would use those pairs as well

Only passive Poe would. So don't use a passive injector.

Use a Poe switch

Not exactly

 

Depending what "mode" the poe is set up

 

Mode A no

Mode B yes

 

Both are defined by 802.11af

 

The power source device would determine which pairs (or mode) is used

 

I would say that if pins 4578 are not connected that the switch would use mode A, unless the device calls for more wattage.

 

I will also say that an install where you are breaking up pairs in an Ethernet cable is a very sloppy install and will create more problems down the road

Thanks folks , will take all those suggestions on board , and use them until I find which is most suitable for my app.

 

Cheers,
