RJ45 Couplers with POE?

[J273]

Hi all,

I have a few camera's which id like to change their location but i can't run a new CAT6 feed. Is it safe for me to use RJ45 couplers with POE cameras to extend the cat6 feed i already have in place.

Something like these? Are they ok to be used with POE? Anyone use them without any problems?

It's not the best option, but sometimes we gotta do what we gotta do. Do all the waterproofing stuff to it.

As long as they have all the pins.
I've seen some that skimped out and only had the 4 pins used for data.

I totally understand the suspicion, all I can say is they are working for me in multiple places. The only problems have occurred when I didn't do a good enough job of waterproofing.

It's no different than going through a patch panel. Some of my cams go through two patch panels before they get to the IT closet, where they go to another patch panel then to the switch. From there it goes to the outlet at my BI server and then to the NIC.

If it's an outdoor extension of an existing cable, use something like this:

For indoor, what you found will work just fine.

I've done both methods, and have not had any problems.

Just in case you're not familiar with the term "waterproofing" mentioned a couple of times above, I've linked my method at the bottom. Even in areas not directly exposed to the weather such as a crawl space or attic, at the very least I'd use the dielectric grease as mentioned in my method, as prolonged exposure of the metallic contacts to the ambient humidity can produce some oxidation and corrosion. It doesn't take much of it either to cause issues with circuits of so little current.

Can I have some help with how to correctly install the following please Junction box: HikVision DS-1280ZJ-DM21 IP cam: HikVision DS-2CD2347G1-L(U) The IP camera comes with a waterproof gland that seals the RJ45 connectors together in a watertight fit but I didn’t manage to get it to fit into...
