I learned from the news some time ago that Vision Power’s “One Network and Two Lines” project won the 2020 Government Informatization Program Case Innovation Award at the 2020 Government Informatization Conference. We all know that as one of the few high-definition video communication companies in China that has independently developed communication protocols and has a leading market position, Visionlink Power has launched the "one network, two lines" project, in the overall framework of one network for e-government external networks. It has very good effect to achieve secure data and video transmission over two wires.
