The leading and founding member of CCHDTV Alliance, ITE Technologies is a public IC design company from Taiwan. ITE’s CCHDTV-spec chipset is the core of all DTV surveillance products/solutions. The unique and robust digital transmission technology of  the ITE chipset allows DTV surveillance products to send digital video and audio further than 1km on a 5C-2V coaxial cable without any repeaters. 

Ultra HD DTV surveillance debuts at the CPSE show included 4K DTV cameras and 4K DTV DVRs. Supporting multiple 4K video over one coax cable,   the DTV surveillance system is currently the only solution known to be capable of simultaneously delivering multiple digital 4K videos over one coaxial cable. Just like IP cameras, DTV surveillance cameras send digital video using digital transmission. But, unlike analogue and analogue HD cameras, the video quality of the DTV cameras is designed to be insensitive to the quality and length of the coaxial cable.

Due to the use of coded OFDM for transmission, DTV cameras feature suprerior wireless transmission that is able to achieve a wireless transmission distance of up to 500 metres in an open space. The DTV wireless products are therefore ideal for places where cable installation is difficult, for example, seashores, mountain areas, construction sites, etc.

CCHDTV Alliance members, A-Tec Subsystem, Fuho Technology, and Ubiquity Smart Technology joined-forces to showcase their DTV surveillance solutions and products for the demands of wide-area, long-distance, and hybrid system applications at the event.

Surveillance specialist, Fuho Technology, was an early adopter of the CCHDTV surveillance technology. Fuho has developed and presented many models of DTV cameras and DTV DVR’s, powered by the ITE chipset. The DTV surveillance solutions from Fuho, according to the company, have proven performance and capability in terms of transmitting multiple channels of 1080P at 30fps and 1080P at 60fps over a single 5C-2V coaxial cable up to 1 km without any repeaters required. 

The DTV surveillance products from  A-Tec Subsystem are equipped with a power over coaxial (PoC) feature.  As the power, video, and control signals are all multiplexed in one cable, A-Tec's DTV suveillance products stood-out due to this so-called “one-cable solution” that is ideal for applications where the electrical infrastructure is limited. With 5C2V cable, the transmission distance has been, according to A-Tec, proven to reach 1 km without any repeaters; if transmission is via optical fibre cables, then the video could be transmitted as far as 50 km. This meets the security requirements for installation in large fields/areas, such as farms, forests, and amusement parks.

UST (Ubiquity Smart Technology) demonstrated three themed solutions of their 16-channel V100 Series, 32-channel P100 Series, and 64-channel E100 Series hybrid (IP+DTV) DVR’s at the CCHDTV Alliance stand. These hybrid DVRs constitute a suite of scalable products that match the growth of companies from small to large and local to worldwide.

In addition, as many as 16 digital videos can be daisy-chained onto one single coaxial cable using inexpensive cable-TV power splitters. These unique capabilities enable easy integration of DTV surveillance products into digital security systems, IoT, or cloud applications.
