Dahua RJ45 Connector (Balun?)

Recommended Posts

Has anyone cut the connector off and extended the flying lead?

Or has anyone disconnected the lead from inside the camera and connected a longer lead?

 

The reason i ask is i at the moment i have my cameras mounted on 75x75x40mm junction boxes with the "balun" inside. I want to tidy up the installation so the camera is mounted direct to the wall but the lead isn't long enough to go through my cavity wall. I also do not want to have to drill a 25mm hole to fit the connector through!

 

Is it as easy as disconnecting the lead from the camera and creating a new lead using a female RJ45 connector and a bit of cat5e?

 

Cheers.

So...

 

I've had a look inside the camera working out what core goes where.

 

The lead is a 10 core cable connected to a 12 way female IDC connector coloured as below.

 

1 - Blue

2 - Orange

3 - Purple

4 - Brown

5 - Black

6 - White

7 - Red

8 - Green

9 - Grey

10 - (Empty)

11 - Yellow

12 - (Empty)

 

Using my multimeter i worked out what cores from the RJ45 socket goes to what... (TIA568A)

 

1 - White/Orange > 4 - Brown

2 - Orange > 3 - Purple

3 - White/Green > 2 - Orange

4 - Blue > 11 - Yellow

5 - White/Blue > (Not used?)

6 - Green > (Not used?)

7 - White/Brown > (Not used?)

8 - Brown > (Not used?)

 

I've not tried pulling the lead out and creating my own as all the cores seem to have connectors on the end like below...

Which keep them in the female connector, i haven't got any so i'll have to leave it for now.

 

Am i right in thinking i only actually need to connect up 2 pairs?

 

Cheers.

Did it work for you?

 

I'm also trying to use the rj45 cable as Power Over Ethernet, so I'm guessing it will use all 6 cables.

It worked by adding the two remaining cables (no5 & no6) with blue and grey.

 

So the order is :

 

1 - White/Orange > 4 - Brown

2 - Orange > 3 - Purple

3 - White/Green > 2 - Orange

4 - Blue > 11 - Yellow

5 - White/Blue > Blue

6 - Green > Grey

7 - White/Brown > (Not used)

8 - Brown > (Not used)

 

Voila!!
