Description about AHD Generation


AHD is a newly developed solution for transmitting full HD digital video in a surveillance system. The core concept of AHD is to deliver high definition video using digital TV (DTV) transmission. With AHD, high definition digital video can be transmitted easily over coaxial cables, twisted pairs, or simply over the air.



What to expect

AHD leverages the extremely robust AV transmission capability of HDTV to easily and seamlessly upgrade an analog cctv surveillance system to digital full HD. It is expected AHD to become a de facto standard for digital video surveillance systems in the future.


HD Performance at 1080P

The MegaCam HD product family is based on AHD (Analog high Definition) technology and is ideally suited to upgrading existing standard definition systems at low cost. It retains the ease-of-use of an analog system while offering up to 1080P HD video output. Multiple 1080p30 video streams can be easily transmitted using AHD over a single 5C2V/RG6 cable up to a length of 500 meters without any repeater (Up to 300 meters in case of 3C2V/RG59).


New Technology from MegaCam

AHD is a novel technique pioneered by Nextchip. Nextchip has devoted much resource into the development and promotion of AHD solutions. Nextchip has developed key enabling products, reference system designs, and applications for AHD . These products and applications enable seamless and friendly transition of video surveillance systems from analog to digital, be it all-new digital installations or upgrades from existing analog installations.
