work with hikvision dahua cctv camera 1080P hdcvi TVI AHD to video fiber optical converter,with 1-channel reverse RS485
Description
It’s digital optical transmission system optimized for single-channel, which could compatible with the all-pattern video signal hold out 1-ch unilateralism signal at same orientation on an optical fiber. For obtained high quality transmission, the video signal adopted 8bit/10MHz digital sample technique full-digital transmitting channel. Power, optical video are easily inspected the indicators on the panels, so that the user could check the status visibly. The system series are high performance reliability transmission system for long distance of video
