OVER VIEW
FI-VOF4XXXX series supports any high resolution dynamic or stationary picture high-fidelity transmit. It also can be anti-disturbance against several signals, environment, and work stably. It is widely used in security monitoring and control, high way, electronical policy management, automation control, intelligent residential districts and so on.

It can work shortly after it is installed. You could select any date interface by set. It is connected easily and it can indicate power supply, link, video, also adjust video. There are two way installation kits available: stand-alone and rack mounted;

It can be used in varios ways, for example:
        Intelligent transportation system; 
        High speed way video monitoring and control system; 
        Toll monitoring and control system; 
        Close circuit TV industry monitoring and control; 
        TV program switching channel transmit;
