Для каких проектов нужно CCHDTV?
Current ccHDtv Projects at a Glance
1. A molding factory in China uses 16 ccHDtv cameras with the requirement for a transmission distance over 250 meters. The ccHDtv system provides better image quality, compared to IP video surveillance, with long-distance transmission.
2. A mechanical parts factory in China uses 16 ccHDtv cameras with the requirement for a transmission distance over 150 meters to replace its existing analog system.
3. A commercial building in Taiwan uses 16 ccHDtv cameras with the requirement for a transmission distance over 100 meters. 16 ccHDtv cameras are connected with four coaxial cables to replace its existing IP video surveillance system
4. An elementary school in Los Angeles, U.S., uses 12 ccHDtv cameras with 120-meter transmission distance. This is a new project with 12 ccHDtv cameras connected into one coaxial cable.
5. Bank of Shanghai in China uses 12 ccHDtv cameras with the requirement for a 120-meter transmission distance. Based on its existing analog video surveillance system, the bank added 12 extra ccHDtv cameras.

Unifying ccHDtv Suppliers Through an Alliance
With ccHDtv technologies and products getting more mature, ITE is also able to include more partners and suppliers of ccHDtv products. The company, then, established the ccHDtv Alliance this January to consolidate its marketing and sales strategies. ccHDtv standards and specifications were first announced to the market in Nov. 2012. Now, the company has over 10 qualified Taiwanese manufacturers that have adopted these specifications to develop their individual product series. «ITE provides allied companies with full support and services, including tests, certificates, and system integration, to help them manufacture a next-generation HD digital surveillance system with high quality and efficiency,” said Lin. Through the alliance, ITE hopes to bring ccHDtv to another new level, by collaborating and consolidating the resources from all the members, especially when exploring international markets.
ccHDtv now is still in the early technology introduction phase of its product life cycle. It needs more partnerships from security suppliers and recognition from global systems integrators in order to expand its market shares. ccHDtv provides systems integrators another option when implementing a video surveillance project, which is especially beneficial for both sales channels and end users alike. With this, we hope to see a significant growth for ccHDtv in the near future.
What makes ccHDtv unique is its «transmission technology,” according to Lin. Based on DTV technology, ccHDtv uses COFDM and radio frequency (RF) transmission technologies, which bring many benefits to the whole system, such as high noise resistance and bandwidth. He further explained that current IP video surveillance system use TCP/IP transmission technologies to transmit digital signals over Ethernet cables. Therefore, an IP video surveillance system usually has image latency problems. It goes without saying that these problems might get worse when transmitting 4K video. However, ccHDtv is different from IP because of the COFDM and RF transmission technologies…… Read On
