Rain can affect Ethernet connections.
Rain can affect Ethernet connections.
It's been roughly a month since I installed my security cameras, and everything is running smoothly except for a few small software problems. That’s not why I’m writing today. My goal here is to ask for assistance. Yesterday it rained heavily, and when I checked the cameras, one of the Ethernet heads was completely black—likely from the moisture. My question is, can I just replace that Ethernet head so it works again? Should I cut a bit of the cable and plug in one of these heads? [link] If this fixes it, I’d appreciate it. I prefer not to replace the entire 100-foot cables since they’re long. Also, for those who think this will happen again, I’ll use the waterproof cap that came with the cameras. The only reason I didn’t install them initially was because I wasn’t sure how, so I didn’t bother learning until it was too late. Thank you in advance for any help. By the way, the cameras themselves are still functioning—my tests with other Ethernet cables confirmed they work fine.
For outdoor use, it's wise to opt for cables rated for harsh conditions. Regular cables tend to degrade and crack over time due to exposure. Make sure the weatherproof seals around the camera remain intact—any moisture near the connections can cause serious problems.
I would also close the ports after inserting the cable using a waterproof sealant such as flex seal, silicone, or similar materials.
Dielectric grease simply refers to a substance that doesn’t conduct electricity. Dielectric materials act as insulators, often changing shape when exposed to an electric field through molecular polarization. Although they can respond to the field, they remain non-conductive and won’t allow direct current flow. This property is similar to what’s used on spark plugs to repel water from the HV connections and stop arcing.
You're right, I was considering noalox. Let me know if you'd like to discuss it further.
