      product related question: if you are sharing your IP address with others who may be bad actors, could that get your IP address banned from certain services, or at least make it look like you are the one doing bad?

    As a network engineer, I can confirm everything in this video is correct. They are well researched. I would only add that if you're looking to buy a PoE injector, that you carefully read what the product is and what standards it follows and look into if it's active or passive. Just like how different switches have different capabilities, so too will PoE injectors.
    Also be aware that PoE splitters are a thing too and can often look like PoE injectors so carefully read the product labels and specs when buying. They don't add power to an Ethernet connection, they only split the power already on the line up to be able to power more devices. I personally never saw a need for PoE splitters in 20+ years of working on networks and if any time I needed more PoE ports, I would just put in another switch or replace existing switches with bigger switches, but since PoE splitters exist, it's something to know about so you don't buy the wrong thing.

    • @Heizenberg32
      @Heizenberg32 Рік тому +3

      As an installer my solution is simple: Do not use passive PoE! Do not buy them, or even manufacture them, except for specific use cases and are clearly marked as such. Even then, mistakes will happen. Even if the injector is plastered with warnings to not plug in your laptop to it: The far end of the cable won't be.

      Question. How does IP phone get data and power from one pair only? Because in my organisation it does

    • @gwgux
      @gwgux Рік тому

      @@Vooker525 The only type of phone I know that does that is a traditional analog phone, not an IP phone. For all IP phones I've worked with on a network, they've always used the same two data pairs as a PC would for 100Mb Ethernet leaving the other two pairs for PoE, or like for our 1Gb phones, they use all 4 pairs for both data and power at the same time as described in this video.
      If I had to guess, you may have something that runs similar to DSL where data is sent down a phone line and it still has it's own current like a regular phone like would.
      Usually analog business phones have two or three pair phone lines for circuit switching, putting people on hold, etc. (the reason why a desk phone could have someone on hold while talking on another line) switching and may even have a display, but those are still not IP phones.

    I do have a request that I would like to ask you. Could you please explain UID for cameras? Do all IP cameras, newer ones, have a UID number?
    I have a program call P2P client v6.5.6.4 that works Great. The cameras I have are called Boavision. What I like about them is that they are UID type and that work over the internet without port forwarding, all i got to do is add the UID number in the program under setup and the username and password to the camera and give the camera a name. The camera could be in Alaska or Michigan it don't matter as long as it has a UID number.

    Great video! I've been working with PoE technology since its emergence and it's rare to find such a comprehensive and concise explanation. I particularly like that you touched on passive PoE devices. Though old and rare, they do still exist (mainly running older building equipment). Just a year or so ago I had someone try to daisy-chain one of those through a modern PoE switch that we had just installed and ended up cooking $5k of hardware!

    Do you have more information on the handshaking method that PoE uses? AFAIK when a connection is made, a PoE switch does not put power down the line until it's requested, but if the requesting device does not have power of it's own, how does it wake up to do that handshake to say I need power?
