thanks, being not an expert in light current, what the solution if I've a an outdoor PTZ camera with more than 70 watt power budget, how can I supply it through poe if maximum pse capability is 71 watt?
Not necessary. The power is measured in Watts (W). Voltage (V) is a factor of power. Increasing the voltage will allow a cable to deliver more Power or Watts at a lower Intensity (I) measured in Amperes (A). The goal is to deliver more power but to achieve that we increase the Voltage on some cases.
No, it should not. The switch will only send power from the port after a comunication is initiated and the device is identified as a POE device. However this may not be true with a mid span device.
I have what I believe is a standard poe switch then. It says it can do 17 watts max per port. I've been trying to find a wifi 6 AP that uses this. I also have two point to point antennas which came with a 24v poe injector. Guessing thats called passive. Assuming its always going to apply 24v on the line no matter what is connected?
Yes the POE injector (also called midspan) will add the voltage to the line. not sure how it will work if you have a POE switch it depends on what you have.
@@KnowledgeBase2020 well the switch i have i know wont power my point to point antennas. I was hoping I could find a wifi 6 ap though that used standard poe though. So far no luck.
Hi, my Power device needs POE 802.3af, can I use CAT 6 cable to supply power to the device as CAT 6 cable is 802.3bt that carries more watts that the powered device needed? Will it damage my powered device? Thanks.
Hi, sorry for the late reply. yes, you can do that. if the cable is rated for higher power this will lead to a better performance and less power wasted in the cable. Depending on how far your device is from the source you may want to consider a lower gage (thiker wire) for the installation.
Hi Anthony, Passive POE is a non standard POE and I would not recomend using it as it could cause damage to your network devices in the voltage requirement is not matching.
The 802.3bt standard came with two new options: Type 3 and Type 4. Both refered to as POE++. The POE device you are using will support one or both types. You can know that from the device specifications.
have questions I put 3 poe switch with full ip camera but video is stak stak but if i connect only two peo switch is working ok but if i connect 3 together video is stak stak what is problem
Hey Said, this is a network issue. You need to configure the network to make sure that the total bandwidth from the cameras in not hitting a bottle neck somewhere in the network.

Thanks for the question. you can use a power injector or also called a mid span to power your PTZ Camera.
basically the difference is more voltage in each type right?

Good day, would a PoE+ switcher damage non-PoE+ device when you plug it in one of its PoE+ port? Thank you.
No, it should not. The switch will only send power from the port after a comunication is initiated and the device is identified as a POE device. However this may not be true with a mid span device.

What about POE devices that support passive 24V? Is that not part of the 802.3XX ?

Thank you for this quick/easy explanation that didn't get too deep.
Your volume is very low though & I had to max my laptop to hear you.
Thank you for the feedback, I am happy that you liked it.
I will try to adjust the volume in the future videos.
Question: is type 4 = POE +++ or POE++ have type 3 and 4 (if so how can you tell with one you have)
