Power Over Ethernet (PoE and PoE+) - in 5 Minutes

What about POE + ? Do they make something to convert POE to POE + I have POE but need POE+ for a security camera? How can I accomplish this

for POE do not use copper cladded cable will over heat and cause fires

I remember we used to use those injectors on my mom's laptop back in 2011 😂

What an awful idea. This reminds me of the late 80s and early 90s, when a single bad node on a 10baseT network was able to short out and cause thousands in damage to the rest of the network because a 25 cent part went bad. No thank you.

hello,! how much power output needed to power a router 12v 1a wired repeater(rujie 1200 pro) with a distance of 30meter upto 50meter I'll be using a rujie 1200 pro as main router and ax1800tplink or rujie 1200 pro as wired repeater that are connected to the main router but I don't know how much power I need there are 52v,47v 1a, 24v 1a, 15v 1a , 12v 1a as the option for POE adapter or POE injector

well explained

With a Tplink, POE injector, can we connect to a 12v DC camera? The tplink injector produces 48v output DC.

The PoE switch is a really great thing, and the video is great, everything is described quickly and precisely about this type of devices ... I started my adventure with PoE on the IES6210-4P2GC switch and it still works great, I recommend it!

If you have an NVR device for your security cameras (poe), should you still get a switch? I am interested in getting a security solution that has the option to connect and power 12 cameras (they say it’s just plug and play).

ahh so this is how these injectors work.
Thank you

Maaaan, I love how you pronounce "Microtik" as "meecro-"! People don't realise how irritating it is to hear "raspberry pie", "golden number fye"... -that's what I was going to say until I heard "raspberry pie" right at the end of this video :D

Am I the only one who initially thought POE was somehow hooking up ethernet to a regular power outlet via maybe an adapter and then have full ethernet speeds?

Hello Gary, thank you for this excellent video and instruction. I am a newbee so pardon my question. Does the TP Link injector provide power for one device - in other words, if I have more than one device that is not POE compatible, do I need one injector for each device? Also, the description on Amazon does not include support for Windows 11. Can you recommend a Windows 11 compatible injector?
Thank you in advance.

Hello, does that mean that a typical wifi router that was issued by ISP providers does not contain POE capabilities at all?

Can I connect a PoE into a normal switch that is powered externally?

One thing I'm curious about is what wires in the cable deliver power? (And is color standardized like yellow is power and brown is data or maybe blue could be power or data)

I have a POE Wifi Accesspoint. Can I run that cable to A Sonos Music amplifier first then up to the Accesspoint without damage to the amplifer?

Keep up the good work Gary !!!

So not all devices/ports support POE?

Very nicely described, Thanks

ong

will it work on ip camera with Ethernet socket?

OK FANALI GOT THEAT .DEFENETLI . OK BUT FOR WAT ELS EXEPT SECURITI CAMS SC CAMS !!! HMMM

Is there technical difference between yellow and blue etherent cable? my AP outdoor device not tuning on with yellow

thanks for the video. How many cable pairs does the PoE needs?

Why do I have to put in the data cable? I was trying it with power only but this doesn't work. I need it just for the power component.

Is all these cat5e and Cat6e cable are POE compatible?

Thanks, very helpful.

Can higher wattage PoE++ be used with regular cat5e cables or do they need higher cats or special types of cables to handle the current?

Thank you for the clear explanation

Nice video. What is IEEE802.3az do you know ?

Man you're so underrated

POE is an absolute blessing when fitting Closed Circuit TV cameras. I use CAT 6e because some cams with IR, UV lights are a bit more hungry for power

Does POE degrade speed? ie, from 1Gbps to 100mbps? because that is what I am getting - or I am using a poor POE injector?

I have no idea PoE is a thing lol

Awesome explanation!

Ethernet cable has like 8 wires in it would have been nice to know which lines were the power and which lines were data or does both get transmitted over the same lines?

What's the difference between power and data? How a device or PCB distinguish between power and data ?

Come on ... put the next video up!

Super! 🙌

GARY!!!
Good morning Professor!
Good morning fellow classmates!

Wow this is awesome!

I think Power over HDMI (or MHL) needs to make a comeback! There are so many streaming dongles & sticks sold these days and what's holding me back from getting one is the unnecessary cabling I'd need. My TV even has a MHL port but no stick or dongle supports it 😫 The right place to start removing the charger is on these things as there are better ways (for consumer AND manufacturer)

But if you have the injector that close to the device it's powering, you might as well just connect a power supply directly to the device.

👍

Good video.
I didn't notice Gary say but POE uses the standard cat5 etc cables (not a special cable).

Building my PoE home network tomorrow. Received all the TP Link Omada equipment today! (AC200 cloud controller, WAE235 access points, S2235 network switch, ER605 router from TP Link Omada and some Netgear PoE powered PE switches) will be lots of fun!!!

Sorry about this, but this was a useful video in 2002...

Who else understands what Gary is about to say before they watch his videos but watch them anyway just because he is a damn fine bloke ?? ;-)

Really enjoyed the video, thank you.
