Digital Video Transmitter and Receiver

1. Transmiting 2 channel Video signal via fiber 2. AL material more light 3. Lightning protection

DTV2000 series VoF unit can transmit 2  line bidirectional digital video broadcasting, 1 line bidirectional high-fidelity audio, 1 line bidirectional asynchronous date,1 line 10/100M adapt Ethernet date to one fiber efficiently.DTV2000 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 data interface by set. It is connected easily and it can indicate power supply, link, video, also adjust video. There are three way installation kits available: desktop and rack mount;

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;High-fidelity video conference system;Security monitoring and control system.Completely digital fiber transmit platform;No need to configuration or any adjusting during the instalation, user friendly design;Based on self copyright IC;No interference between analog in adjusting channel, picture and range;4 steps filtering;Completely digital, broadcast transmition efficiently managed by specific IC;High speed 10/100M Ethernet channel;Full speed asynchronous date channel;Flexible configuration on the same platform;Power supply, link, video by dynamic indication;Self-adapt in PAL, NTSC, SECAM standards;ASIC based design;transmit distance: up to 100KMPower supply:220v,-48v,+24, +12v,+5(optional), any specific on reuqest;SNMP management;Three installation types: wall method, rack in 19inches 1U, or plug in-card.
