Ethernet Wire issues with rain

[SenseiPichu]

So It's been about nearly a month since I've gotten my security cameras, it's been going fine besides some minor software issues. However that is not the reason why I am here today. The reason why I am here is because I need some help. Around yesterday it ended up raining quite a lot, when I went to check up my security cameras one of them stopped working. So I went down to check and I saw this, the ethernet heads are pretty much black. probably due to all of the rain. So my question is, can I simply replace the head of the ethernet cable so it can work? Cut the cable a bit, then put one of these heads https://www.amazon.com/gp/product/B0771MCFQ7/ref=ox_sc_act_title_2?smid=A17K4O9J62HKE5&psc=1 
and my ethernet cable will be good again? I'd rather not try and replace the entire cable since they are 100 foot long cables. Also for people thinking that this will happen again, I will simply use the waterproof cap that came with the security cameras. The only reason I did not put them on in the first place is because I didn't know how to so I didn't bother learning how to do it since I didn't think it was necessary but sadly I was very much mistaken. As always any help will be appreciated and thanks in advance. Also FYI for the people curious the cameras themselves are still fine, I tested them with some other ethernet cords I had lying around and they still worked.

You're fine, go for it. Just make sure you get the wires in the right spot.

Since this is going in an outdoor application I would recommend to invest in exterior grade cables for the outside portion, over the years the jacket on regular cables will break down and crack. Check to see if the weather seals around the camera and such are still good as any water getting near the connections can spell disaster.

I would also seal off the ports once the cable is plugged in with a waterproof sealant like flex seal, silicone, or other sealant.

You can also pack the connections with a dielectric grease to keep water from getting into the contacts.

you'd be better investing in a corner jack to plug your cable into in case this happens again

Another thing to add, is install a drip loop in the line.

Dielectric grease is conductive and would cause the pins to short.

Dielectric grease literally means "non-conductive grease".

 

Dielectric materials are insulators that have some form of reaction to an electric field, usually polarization of the molecules.  Even though they can interact with the field, they are still an insulator and will not directly transmit current.  This is the same stuff you use on spark plugs to keep water out of the HV connection areas and prevent arcing.

You would be correct i was thinking of noalox
