Vi-Link HL8D series is a fiber optic digital transmitter/multiplexer for transmitting 8 channels Analog HD 5MPX, 4MPX, 3MPX, 2MPX, 1MPX, TVI/CVI/AHD video signals with PTZ data (Reserve directional) over a single mode fiber optic cable. This robust transmission platform utilizes the existing Coaxial and Fiber Optic cables in the existing system, it is a very cost-effective solution for upgrading the old CCTV Analog Video System to today’s HDCCTV High-Definition Analog Video System.
The HL8D series is fully recognized all high-definition analog video input formats including 25/30/50/60 fps @720P and 25/30 fps @ 1080P, its BNC interface can support up to 500m @ 720P and 300m @1080P. The Multiplexer/De-Multiplexer also offers a fully serial digital video encoding/decoding of real time TVI/CVI/AHD video (10 bits sampling rate at 108 Mhz) providing adjustment free operation over a wide operational range. Utilizing fiber optic AGC receiver techniques for distances from back-to-back to 40 Km, our digital signaling offers superior receiver output stability, which is unaffected by changes in fiber path attenuation due to aging or splicing points.
The extended temperature capability of the HL8D satisfies very critical applications requiring high quality video performance with high reliability. In addition, the HL8D provides Auto Signal Compensation (ASC) allowing low signal distortion compensation over long distance transmission. The transmitter is a rugged standalone compact unit, and the receiver is also a rugged standalone or a plug-in card for the rack version.
Applications include City and Highway Traffic Monitoring, METRO and Railroad Monitoring, Oil & Gas Monitoring, campus Security Monitoring, Airport Security System, Military Security Systems or any application requiring HD quality video performance.
