The PD is still off but presents a resistance value on its input port based on the required “Power Class”. The PSE sends a “Classification” pulse to the PD. The PD is off at this point but presents a resistance value on its input to let the PSE know that there is a valid PD at the end of the wire.
The Power Source Equipment (PSE) sends a “Detection” pulse to the Powered Device (PD). What are the types of PoE? There are three types of PoE IEEE 802.3af (15.4 Watts IEEE 802.3at (30 Watts) PoE++ (60 Watts) The resulting power provided to the camera is a function of: 1) Source power 2) Source Voltage 3) Cable lossħ The standard distance used to determine the power availableĪt the Powered Device is 100 meters /328 feetĨ How does PoE work? The are three steps in PoE operation: What is PoE? “PoE” is defined as Power over Ethernet - the ability to transmit power from a source to a destination over copper wire. UTP Cable is limited to 100m (328 feet ) distances) and many security applications require longer distances Removing coax cables and installing UTP still does not address the 328 feet signal and PoE transmission limitation. Note the expense of: Removing coax cable.
