Video and audio switching is handled by the ultra compact VideoBloX switching and control hardware. The standard 64 output bus chassis offers unparalleled space over competitive systems. Simple RJ45 video interconnecting between chassis allows for clean, compact system designs. Matrix inputs can either be traditional BNC or UTP (RJ45). UTP inputs further simplify system design by incorporating the active UTP receiver and switching hardware on one 16 channel input board. Major PTZ protocols are supported and new device control protocols can be incorporated through macro language programming.
