Power Over Ethernet Using 4 Wires (2 Pairs)

This video shows you how to use 4 wires (2 pairs) for network data and power using 802.03AF Mode A. If your cat5/6 cable is cut and you’re missing a pair or pairs this is what you need to do. Also a great solution if you need to power 2 cameras using 1 cat5 cable.

Thanks for simplifying that for us. I followed your advice and diagram and had my camera working in a short while.

I have been searching for 2 hours on how to add the RJ45 connector to my ip cameras. Finally found you. I just can't believe that this info is so guarded, at least it seems that way. Thank you

This video was very helpful. It helped me for 2 different jobs since I've watched it. Thanks Global Vision

Great, nice and straight forward presentation - thank you

Awesome video! All your content has been gold. Thanks for doing all this.
What do you think of using the hikvision or some other quality branded two wire POE converter together with the injector? Doorbird devices here that I'm dealing with and their converter comes in such a steep cost. Maybe it's worth it, would love your two cents

My 3rd pair ( white/green ) is damaged in my Cat 6 data drop feeding LTS 4MP Turret Camera. If I re-wire both ends, using your video as my guide, do I still need the 802 injector, or can I simply plug back into NVR as it is POE powered already ??

I love you lecture sir u teach me more about configuration of nano, edge and unifi configuration

thanks for thr video
ive got a swann ip camera which is able to powered by poe
it support 802.3af standard, so is it possiable to use 12v to power on the camera
any disadvantage?

[ScottWard-nzxd]

My 3rd pair shows open. Can I re-wire both ends the way you show and simply plug back into my 8 port LTS NVR ( as it is POE powered ), or do I need this 802 injector ?

[drallersouldust]

but how can we still get gigabit can we cut 2 wires only? I only need 2 wires for powering up devices that I'll attach to balun with positive and negative polarity so if there's chance to still achieve gigabit connection I'm on the look and don't know what wire numbers like 45 78 should I cut

[kyah]

Do you think this will work for IP phones ?

[vanzetti]

Hi good day, do you have a link where to buy the power injector . Thank you.

[ahmedalahmari]

Nice, so that mean I can use one cable for connecting 2 IP camera to NVR?

Did you use Hikvision NVR + IP camera in show? thanks

hello. which pair caries 9 - 12v that can power the router in CAT 6 cable?

[bitTorrenter]

If I have good quality modem cable (F/FTP, 24 AWG, 6P4C, RJ11) or 2 pair External Telephone Cable, would I be able to use either of these for a POE IP camera setup if I was to I re-terminate with RJ45 connectors?

[clivecottam]

Which of the 2 pairs provide the power?

[budsmith]

I’m working a property that has their wireless access points running off of two pairs. Having a hell of a time figuring out why I can get power but no data to the AP

[anthonygaming]

Is it correct you would just have 10/100 speed with this?

[bharathnalla]

Can I use normal WiFi router for this kind of broadband connection?
