Specifications

Product name: HC1002M Multifunctional digital video converter

Product category: digital video fiber optic transmission system

Product introduction

1.  Overview

HC1002M adopts the latest optical communication technology, and makes 2-channel positive-going video, 1-channel bidirectional audio, 4-channel sync switch, and 1-channel Ethernet multiplexed over a fiber transmission; video signal compatible with PAL, NTSC and SECAM formats. Easy installation, without any adjustment to the work; could transmit signals of video, audio, data and Ethernet up to 100km above. Now it is widely used in radio and television transmission, video surveillance, railway/highway monitoring, security, video conferencing and other fields.
