Vigitron's Vi0021 ViewMate is a compact but powerful tool for installing and troubleshooting PoE enabled devices. The Vi0021 accuratetly and continuously measures and displays the voltage and power level of PoE at the camera input on 2 separate displays. When connected, ViewMate passes the PoE power from the "Network" Ethernet port to the remote PoE powerd device such as an IP camera thru "Camera" port, and the "Laptop" port provides direct network connection from the remote IP camera to a local laptop for focusing and set up. Powered directly from PoE sources, the Vi0021 doesn't require any external power. It is compatible with IEEE 802.af, IEEE 802.at and most non-standards PoE systems up to 60 watts for 100/10 BASE-T environments. ViewMate's patent-pending design offers a small and rugged packaging. It is an ideal diagnostic tool for all installers working with both CCTV and IT PoE systems.
