I found this interesting, it’s funny that the first comment was so negative considering the fact that ANY information gained is a step closer to ones goal. I think if you get the time you should do a follow up to this DIY because it is a little misleading if you query DIY Power over Ethernet injector and this page is hit. With DIY you tend to ASSUME an answer.
Make it Power over Ethernet Adapter for Dummies or something :0)

Keith,
I never cease to be amazed by how people like Jf can be so dense and malicious. This blog post probably saved me a days worth sweat and cursing trying to get this thing to work. Thanks for your help and keep up the good work.

There is also easier way to do DIY PoE for Axis camera:

It doesn’t look so pro but it’s working =)

Interesting, I have two of those cameras and I can not get them running!…I decided to open one of them and found a dead battery inside, replaced with a fresh one and is still not good. Any idea ?

With regards to the simple way that JM also used, what pair’s are unused?
1,2 and 3,6 are used for 10 base communication. Do you use 4,5, and 7,8 for power and ground? I haven’t cut into my only power adapter that was included with a M1011, but I’d think I can also extend power using the included power adapter that came with the M1011 by splicing and making a custom network cable, only using 2 pairs for data, and the other 1 or 2 for power. Would this create any cross-talk running the power accross like this?

Sorry for the basic question. I’m a network guy wih little electronics knowledge.

I used “The Simple Way”, Kieth, and it works fine. I’ve had around ten 2100′s running this way for several years with no problems.

Robert, I haven’t got this going yet — waiting on fabbing some T-track camera mounts to attach these to the ceiling. But I’m thinking when the time comes, I’ll just get a couple of “biscuits” (wall-mount telephone jacks) and use them to create the power injector / splitter set on pairs unused at 100M. If I remember, I can write it up when it happens.

I don’t think doing real PoE with these cameras is very practical, much as I’d like it to happen.

I have several of these cameras and each could benefit from this! I’m an IT guy, so I have access to cabling gear, but would love to see photos of how you actually put these together.. and also, specifically, what spliced to what and where! I don’t need to run more than 30 or so feet from my power source and switch, so this could be very helpful!

Thanks!!!!!!!!!!!!!!!

jf is a jackass. Keep up the great work Keith. This post was insightful. I’d love to hear more, if you’d like some window dressing for your blog in regards to theme design let me know.
