yeah yeah so it happened to me. Water entered the connector after heavy rainstorm in CA. The rj45 male cable corroded. The female rj45 attached to the camera also incurred damage and now the camera won’t boot. Seeing how others have been able to fix it, I was wondering what kind of connectors and solutions are you guys doing to fix this problem and ensuring that the new fix will result in a watertight seal as well? Yeah this is a Poe camera. Please let me know which parts you used to rebuild the connector.

Thanks
 
There is a high probability that you damaged the Poe module. You need to first replace the connection. Search for the dahua pinout.
Next time use cosx seal.

I just used a regular CAT6 keystone to replace mine... had one handy. It’s larger than the normal Dahua end, which was not a plus. I wrapped self-sealing tape around the whole repair to help with water (plus dielectric grease in the connecting area), but no way it’s as waterproof as the original end.

I "Think" this also happened to me but could never prove it because the cam was mounted inside.This is how I fixed mine.

thanks for the responses. The problem is that the cat6 cables I am using come with a sleeve. The sleeve is too big and ends up not fitting correctly in the dahua connector housing> i did my best to tape everything up but somehow, in heavy rainstorm, water was still able to enter and drip in.

So I need to buy or make my own RJ45 cables without the flexible sleeve end. Then the dahua round connector will be able to fit and seal it properly. I still will probably wrap it up with something.

yeah the connector looks like burnt brown just like your pics.
 
Besides tape, run up to Home Depot and get a bottle of dielectric grease (it’s a clear gel) and fill the connector with it before you plug in the Ethernet cable. If water/condensation gets through the wrap, the gel will physically keep water off of the pins.

You don't need to use the connectors... What you need is coax seal / silicone tape... Wrap the connection real good and you're done.
 
So do you use coax seal first, and then wrap it over with silicone tape? Also is coax seal capable of sustaining hot california sun all day?
 
I agree my camera may have suffered internal damage. It's funny. When I look at the NVR recording, I can see just before it's timely death, the continuous recording kept going in and out for the last 10 minutes. It would get recording and drop in and out. Finally threw in the towel at 5AM when rainstorm was the heaviest.

I realized how I screwed up. I had mounted the connector joint where the RJ45 cable enters the camera connector housing upwards. I should have angled it downwards so gravity can't allow water to enter the rubber boot/grommet where the rj45 enters.

Lesson learned for me.

I think it is one or the other. Dunno about coax seal and hot days.

Works great on hot days. Coax is installed outdoors. I have used this on practically every camera I have installed. Never had a problem with water.
 
Been there done that! One of my cameras died a similar death. But it still works using the power jack that powers the camera directly, not using POE... Have you tried that? Connect a 12v power adaptor to that jack and in a few seconds your camera should start booting up.

If so, you can use something like this to still use POE:
