Water on rj45 blown

Getting the hang of it

So some how I have got water into the rj45 and it's burnt the contact and some of the plastic has melted at the back.

Camera has went off. Does this mean the camera is completely dead? Could I fix it I cleaned the contacts and tried a new cable still dead.
 
If it got plastic melted, that looks like a bad scenario (high current rush). Somehow the water (conductive) created a short within the camera components (?). If you already tried connecting a 12v power supply, it could be a voltage regulator, etc. With so many micro-components, maybe is time to replace

The increased contact resistance due to corrosion caused a voltage drop between the 2 mating components (the male and the female) and that voltage drop produces heat....which melts the plastic.

It's worth a shot, if you are pleased with the cam's performance prior to this, to do what @iwanttosee suggested and crimp on a new connector(s).

Then you want to waterproof it or even a replacement cam's pigtail like this to help prevent the same issue again.

Interesting so cut off the female put on a male and I can plug that directly into the switch? If that works I buy a female to female connector and waterproof it?

BEFORE you cut anything, if you can identify visually and/or use a continuity checker or V-O-M, discover which wire color went to which pin of the RJ-45 female and write that down.

For now, disregard the colors, just look at the pin numbers of the RJ-45 female which should be what's on the end of the cam's pigtail that burned up.

See if this helps

Damaged Pig Tail Jack - Lemon-aid out of Lemons

Well, I screwed up the pigtail jack on my 5231R-ZE, and it was completely my fault. I was trying out different locations in my backyard, using a premade 50' length of CAT 6, so I was not able to use the weathertight connector that comes with the camera. I am in S Cal, and was not expecting...

Thanks for you help with this I managed to put rj45 on the end and it's working.

I am getting about 60 no single errors a day though so dropping signal for very short periods.

When installing outdoors, or anywhere there might be moisture or condensation, you should squeeze non conductive dielectric grease into the female section of the rj45 before you plug the male connector in. This will completely eliminate any air gaps and resist water entry. I've been using this stuff here for many moons: McMaster-Carr

I had this happen to me but not quite as bad. The camera would work with an external power supply connected to the separate power cable. So I ordered a long power cable that I was going to run out to the camera. I had to replace the RJ-45 connector on the Cat-6 cable feeding the camera. While I was waiting for the power cable to arrive I took the camera down and decided to clean the RJ-45 connector on the camera. I used baking soda mixed with water on a Q-Tip. Under a good light I noticed what look like some kind of "junk" between some of the connectors. So I took my Exacto knife and carefully removed the "junk" beteen the connectors and cleaned the connector again. Presto, the connector now works, so I did not have to run the power cable.

What had happen is the the seal on the RJ-45 connector on the Cat-6 cable had gone bad and allowed the water to get into the connection.

Yep, not sure if the folks that tout those really know what "waterproof" is...I haven't seen one yet; they will do better inside a box or under an eave if they haven't received "the treatment. "

Sounds like possibly a poor/high resistance connection (bad crimp, etc.), that can be thermally or mechanically influenced... have you inspected, re-checked?

No when I get a bit more time I will take it down and check to see if it works connected directly to the switch.
