The Vaddio 999-8700-000 is a single web-based server appliance with a universal browser-based control panel designed to control all of your EasyUSB devices. The WEBBi Browser Control Panel screen allows the user to adjust the volume and MicPOD output levels; switch video sources; pan, tilt and zoom your PTZ camera and store and recall camera presets. Because it's controlled through a browser, you can use a PC, tablet, smartphone, wireless mouse, keypad — it doesn't matter. The WEBBi controls are activated via mouse or touchpad — so if you have a browser, you can control it.
