CPSE, world’s biggest security exhibition, was held from Oct. 29 to Nov. 1, 2015, in Shenzen, China. This year, more than 1500 companies from 150 countries presented their latest security and surveillance products and solutions.
ccHDTV Alliance members A-Tec Subsystem, Inc. (www.a-tecsubsystem.com), Fuho Technology Co., Ltd. (www.vacron.com), and Ubiquity Smart Technology, Inc.(www.ubiquitysmart.com) also jointly showcased their world leading DTV surveillance products. The main themes of ccHDTV Alliance’s booth included multiple 4K videos over one coaxial cable and long-distance wireless surveillance cameras. The members also exhibited solutions for wide-area, long-distance, and global surveillance system de-ployment.
The founding member of ccHDTV Alliance, ITE Technologies, Inc. (www.ite.com.tw), is a public fabless IC design company in Taiwan. ITE’s ccHDTV chipset is the core of all DTV surveillance products. ITE’s unique and robust digital transmission technology allows DTV surveillance products to send digital video and audio farther than 1km on a 5C-2V coaxial cable without any repeaters. 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.

Multiple 4K Videos over One Coax:
Ultra HD DTV surveillance products showcased in CPSE include 4K DTV Cam and 4K DTV DVR. DTV surveillance system is the only solution 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. Thus, unlike analog and analog HD cameras, the video quality of DTV cameras is insensitive to the quality and length of the coaxial cable.
Long Distance Wireless Surveillance:
Because DTV cameras use coded OFDM for transmission, they can also be used for wireless surveillance. DTV wireless products can achieve a transmission distance of up to 500 meters in an open space. The products are good for places where cable installation is difficult, for example, seashores, mountain areas, construction sites, etc.
Smart Single Coax Transmission:
The reputed surveillance maker, Fuho Technology Co., is an early adaptor of the ccHDTV surveillance technology. Fuho has manufactured many models of DTV Cams and DTV DVR’s using ITE’s chipset. At CPSE, Fuho exhibited their DTV surveillance solutions for multiple 1080P@30fps and 1080P@60fps video transmission over a single 1 km 5C-2V coaxial cable without any repeaters.
Wide-Area and Long Distance Solutions:
A- Tec Subsystems exhibited their DTV surveillance products with power over coaxial cable ( POC). The power, video, and control signals are all multiplexed in one cable, thus enabling the so-called “one-cable solution.” This solution is best for places where electrical infrastructure is limited. With 5C2V cable, the transmission distance can reach 1 km without any repeaters. And if optical fiber is used, then the video can be transmitted as far as 50km. This meets the security requirements for very large installation sites or very remote sites, such as farms, forests, and amusement parks.
Multinational Global Business:
UST Inc. demonstrated three killer products at the show: the 16-channel V100 Series, 32-channel P100 Series, and 64-channel E100 Series hybrid (IP+DTV) DVR’s. These hybrid DVR’s constitute a suite of scalable products that matches the growth of companies from small to large and local to worldwide.
