Fix TRENDnet TV-IP310pi Corroded PoE Connector

Following Storm Doris back in February 2017, one of my cameras at the back of my house stopped working. Part of the roof had been blown off (only a plastic cover, thankfully nothing more serious) which exposed the cable and allowed things to get a little damp.

On closer inspection the 3 far pins in the connector had corroded as seen below, click any picture below to see a bigger version:

I’m presuming the corrosion had been going on some time and the storm was the icing on the cake. I tried a mixture of WD40 contact cleaner followed by a strong acid based electrical cleaner and the pins had cleaned up nicely but it still wasn’t working.

I was really trying to avoid was chopping the connector off completely as after all it is over £100 worth of camera, but that happened…

As you can see from above I opted for jelly crimps (scotch locks) as these are waterproof, the alternative was either a  surface mounted punch-down box or RJ45 coupler both which would have corroded over time and eventually left me with a broken camera again.

After making sure everything was working I wrapped the jellys in a fair amount of electric tape followed by a healthy dose of vaseline.

I would have exposed more of the camera cable which would have made things look neater and given me more room to position each jelly connector but ultimately I wanted to cut as little as possible, and the fact it was now working again was a good enough excuse to leave it alone!

Colour Combinations

It came as no suprise that the camera didn’t use standard 568B colours but here is the combination I used:

Key: 568B Standard Cable / TRENDnet Cable

  • Orange WhiteOrange
  • OrangeYellow
  • Green WhiteGreen
  • BlueGrey
  • Blue WhitePurple
  • GreenBlue
  • Brown WhiteBrown
  • BrownWhite

I found the colours by refering to this guide here. I did manage to get the green and green white cables mixed up, however this hasn’t affected the camera in any way that I can tell. If it does ever cause a problem I will swap the cables around at the patch panel to avoid having to tamper any further.
