About us
Zhongchuang Technology Group Limited was founded under the eagerness to stir up the
wireless video transmission technology. With Fudan University’s Electrical Engineering degree,
our founder Mr. Jianjun Gong has dedicated his 30’s in satellite telecommunication. Therefore,
after a solid practice and a profound education, he started this wireless video company in 2005
with three people.
Now after almost ten years of growth, Zhongchuang has developed most of her products
independently based on the great deal of resources accumulated. With a friendly work
environment, the company has been supported both internally and externally.
Our vision is to be one of the top FIVE companies in video transmitter development and products
innovation. Our mission has always been providing the sound quality products to all wireless
transmission requests.
Our end users are varied from military commanding office to ordinary citizens, from oil field to
forest, from overseas to mainland China. We have served customers like ZTE, Jiangsu Public
Security Bureau, Inner Mongolian Fire Fighting Group, Hunan Forest Fire Prevention Office,
SMT(USA) and Tactical Electronics(USA) as well as RF Revision(South Korea).
Brand awareness:
LinkAV - Link your AV wirelessly!
LinkAV with cutting edge technology of Zhongchuang Technology Group Limited is a brand
established recently to meet the demands of COFDM, TDD or 3G/4G wireless connection
requirements.
In 2005 we founded our international Head Offce in Shenzhen, China, and began offering our
products worldwide in 2013. Over NINE years of experience in the wireless communication
sector has enabled LinkAV to develop world-class video transmission products.
