==Key Differences Between Active and Passive PoE==
===Active PoE===
----
*'''Standards:''' Follows IEEE standards (802.3af, 802.3at, 802.3bt).
*'''Power Delivery:''' Uses a negotiation process to determine and supply the correct power level to devices.
*'''Voltage:''' Typically delivers 48V DC, but can vary based on device classification.
*'''Complexity:''' More complex and sophisticated system with power negotiation and monitoring.
*'''Compatibility:''' Suitable for a wide range of devices with varying power requirements.
*'''Safety:''' Ensures safe and efficient power delivery by regulating voltage and current.
*'''Examples:''' Used in devices like IP cameras, wireless access points, and VoIP phones.
===Passive PoE===
----
*'''Standards:''' Non-standardized, does not follow IEEE standards.
*'''Power Delivery:''' Supplies a fixed voltage (e.g., 12V, 24V, 48V) directly through the Ethernet cable without negotiation.
*'''Voltage: Fixed''' voltage delivery without adjustment based on device needs.
*'''Simplicity:''' Simpler and less expensive to implement compared to Active PoE.
*'''Compatibility:''' Limited to devices that specifically support the fixed voltage provided.
*'''Risk:''' Higher risk of damaging devices if the voltage supplied does not match device requirements.
*'''Examples:''' Commonly used in simpler devices like small access points and basic IP cameras.
===Key Differences Sumarry Between Active and Passive PoE===

Active PoE is standardized, involves power negotiation for precise delivery, and supports a wide range of devices. In contrast, Passive PoE delivers a fixed voltage without negotiation, offering simplicity and lower cost but with increased risk of compatibility issues and potential device damage if not properly matched.
