The MaxiiView VI00022 from Vigitron is a cost-effective tool for installing IP cameras and troubleshooting PoE devices. This compact tool monitors and provides a readout of PoE voltage and power on a monochrome display in real time. A local power source is not required for operation thanks to PoE connectivity. The VI00022 is compatible with 802.3af, 802.3at, and most non-standard PoE sources up to 36W. Once connected, the IP camera's feed can be transmitted via Wi-Fi so you can view them iOS, Android, and Windows devices.
