Passive PoE usually refers to any device using PoE that is not 802.3af or 802.3at.
This includes devices such as cameras and radio antennas that run on 24V PoE.
The only way to ensure complete compatibility with the majority of PoE devices on the market is to stick with the industry standard, active PoE.
What is the difference between passive and active PoE?
What are the Differences Between Passive and Active PoE? If your device uses 802.3af or 802.3at it is considered to use active POE. Passive POE usually refers to any device using POE to power that is not 802.3af/at. This includes things like cameras and radio antennas that run on 18-48V DC PoE.
What’s the difference between PoE and Poe +?
One difference between PoE and PoE+ is the actual Institute of Electrical and Electronics Engineers (IEEE) standards themselves. PoE is 802.3af, while PoE+ is 802.3at. Currently, the max amount of power provided over Cat5 cabling is 15.4 watts for PoE and 25.5 watts for PoE+.
