The Avant series of video overlay cards work in conjunction with the Vigilant series of multi-screen graphics controllers.

The Avant-9 video overlay card requires the Vigilant-Pro quad channel graphics controller. When combined with the Vigilant-Pro, this then provides up to 9 separate video overlay windows. For systems that require more than 9 overlay windows, up to 4 x Avant-9 cards can be installed giving a total of 36 video windows.

The Avant-16SQ video overlay card is the ultimate video capture card providing superior performance and virtually unrestricted video capture capabilities with a single or mult-screen configuration. The Avant-16SQ requires either the Vigilant-SQ or the Vigilant-XSQ when combined with the either of these cards the Avant-SQ16 captures and displays up to 16 separate video overlay windows in real-time onto your Windows desktop.

All video overlay windows can reside on the same screen or scattered anywhere around the video wall. The overlay windows can be independently scaled up/down, overlapped, have video in video etc..., with the Avant-16SQ there is also an on-board 32 x 16 video matrix switcher. This enables 16 out of 32 inputs to be displayed in any combination or selective windows.
