The cable has 10 untwisted conductors. I was about to go for the Ubiquiti PoE over 2-wire adapters but I realized there's enough conductors for crimping RJ45 connectors. I bought a new PoE doorbell with a camera so I guess I need a decent bandwidth and stability though.

this might work although cable is not shielded, just watch the wire gauge if it's usable for 48V transport
trim mortar
the cable itself does seem shielded (second photo, we can see the sheared shield)
but not the connectors themselves

how long is the run?
real plank
yeah at 5m it might work cos its short but running a propper cat6 cable would be better
trim mortar
of course, i'll try but there's like five 90° turns on the way
i would hate myself pulling it 50% and realizing it's stuck
(never pulled a cable before, btw)
real plank
does the doorbell have wifi in addition to ethernet connection?
trim mortar
not sure, it's the Reolink PoE doorbell
doesn't seem so
i prefer to go wired for camera devices
supple jolt
no wifi on poe doorbell 😉
real plank
my thought was that you can get DC poe injectors that you could put next to it so you could run DC down a line you have and then have a short ethernet cable which would power the device but no connectivity
trim mortar
that was the initial plan with the ubiquiti poe adapters over 2-wire
real plank
i know at least some of the reolink cameras (like the one i have) have both poe and wifi but didnt know about the doorbell
supple jolt
just checked, no
supple jolt
i think original idea will work
trim mortar
okay. well for the price of 2 RJ45 connectors and a crimp tool, i'll try it anyway, and fallback to the ubiquiti adapters if needed
real plank
you can get this kind of thing and give it a shot
trim mortar
just wondered if anyone tried it before me
real plank
trying to crimp a bunch of wires into an rj45 will be awkward at best. a breakout is probably easier
trim mortar

oh yeah, even easier than clamp style connectors

why is that?
supple jolt
make shure they fit inside\
real plank
UK amazon link but probably exists everywhere
real plank
make shure they fit inside\
depending on guage i think getting it to fit would be a nightmare
supple jolt
just crimp rj45
trim mortar
okay, never did it so i'll trust you on that 😂
real plank
yeah and the male version also exists
yeah theres a bunch of varaiations on that kind of thing

do you have 8 diff. colors on cable?
trim mortar
just crimp rj45
like, proper crimp or clamp-style connectors?
supple jolt
i love crimp
real plank
do you have 8 diff. colors on cable?
this is a shout, if they are not labled you are gunna have to isolate and lable cables first
trim mortar
do you have 8 diff. colors on cable?
nope, 6 unique colors and 4 cyan
supple jolt
measure resistance and lable 1-8
trim mortar
this is a shout, if they are not labled you are gunna have to isolate and lable ...
that's not a problem
trim mortar
i love crimp
well i have a bit of headroom to fail so i might try the real thing!
trim mortar
measure resistance and lable 1-8
what's the resistance technique? i was thinking about connecting a known color cable on one side, and a cyan
real plank
to be fair, if you limit to 10/100 meg then you only need 4 cables...
trim mortar
and just test all the cyans for continuity on the other side
trim mortar
to be fair, if you limit to 10/100 meg then you only need 4 cables...
it should be plenty enough
i'll try that first then
real plank
you will have to look up which cables it is you need for 2 pair. i think its the orange and green pairs but not 100%
real plank
generally there is 8 cables (4 pairs)
trim mortar
at least, doesn't seem so
real plank
for 100 meg you only need 4 cables (2 pairs) the fact that yours isnt pairs isnt the point they will still be "paired up"
trim mortar
yep ok

real plank
so 1/2/3/6 needed for 4 wires
real plank
although i dont even know if poe runs over 4 wires tbh. it might depend on the version
real plank
its been a long time since i messed with anything that's not normal 4 pair connections tbh.
i think there is an ethernet standard that works over 1 pair too but its half duplex so has to take turns sending/receiving packets

where there's a will...
supple jolt
for testing what cable at one end is cable at other end use 2 cables at one side and connect a 9v battery, go to the other end of cable and measure with multimeter all cables until you read 9v on display. Red cable would be plus for that pair, black negative. > mark and label those and then do the next pair..
hope this makes sense
or extend 1 cable on multimeter and measure ohm

well not practically... but I am sure it could be done...

off for today, see you tomorrow

hey it's me again. i've received these
but no pinout was provided. should i assume these as they're coming 1) from a comment on the product and 2) an image search ?
in last resort i'll sacrifice an ethernet cable
nvm i can test on the connector
well a chance i tested it, it's the same order as rj45 pins
trim mortar
seems to have tried the 1g link several times before falling back to 100m
and the 100m seems stable
(nasty i know)
(my wire stripper wanted to make a statement)
supple jolt
so 100mbit works, that should be enough for this use.
allthough i would consider doing a repatch on connector on first picture.. Try to mount the cables without the copper exposed. 😉

ofc that was just the test!
might as well do a proper crimping though
