The Vi00021U upgrades the previous Vi0021 by adding the additional ability to monitor PoE levels up to 60W for both UPoE and 802.3bt PoE types. It maintains real-time monitoring of both voltage and wattage which are equally important in determining if the amount of source PoE is available to power the connected device.
The Vi00021U is in line powered from a PoE with the advantages of not depending on external batteries and providing actual real-time voltage and wattage readers. A monitor port can be used to connect a laptop for direct video viewing.
