One Channel Video with Bi-Directional Data, Point-to-Point Transmission
The FDVA-DB1 series uses the most advanced digital technologies to provide excellent repeatable performance for today’s CCTV systems. It supports transmission of one analog composite video channel and one bi-directional data channel over one multimode or singlemode optical fibre. PAL, NTSC and SECAM video standards are fully supported and the data channel supports all standard PTZ (Pan-Tilt-Zoom) control signals. The plug-and-play design ensures ease of installation with no electrical or optical adjustment needed. LED indicators are provided to clearly show the operational status of the unit. The series is available in compact or 3U chassis card.
