lBrief Introduction of Hikvision VG-1616HC card
VG-1616HC compression board is a professional digital security product, which adopts most advanced H.264 video compression algorithm and OggVorbis audio compression technology. Compared with DS-400xM and DS-400xH board, VG-1616HC can support 16 channels in one board, compress video with CIF/QCIF resolution and preview with 4CIF. Newly designed PCB of the card more compact and steady and compatible SDK interface makes development faster and easier.
VG-1616HC board uses fully optimized algorithm based on DSP technology to implement video & audio real-time encoding, active video & audio preview and motion detection, etc. Video image is directly transmitted from board to display frame buffer and compressed stream is also directly sent to hosts memory. The whole transmit doesnt need any intervention of host computer processor, saving resources of host computers processor greatly. One Personal computer can support up to 64 channels Video and audio input, parameters of each channel can be set independently and will not affect each other.
VG-1616HC compression board supports Windows 2000/XP/Server 2003 and Linux operating system at present, provides demonstration application with its source code, the whole SDK development package including system SDK, player SDK, networks SDK, media Player plug in, etc, and also provides technical support and good after- sale service.

lMerits of Adopting Hikvision H.264 Compression Board
H.264 encoding has the advantage of high image quality , low bitrate and low storage requirement, especially suitable for digital video security. Hikvision H.264 compression board is the state-of-the-art video / audio compression board, which adopts H.264 ACE (ADVANCED CODE EFFICIENCY). Compared with other compression board, its advantage embodies the following aspects:

lSave storage space
Hikvision board compression ratio is higher than those that adopt MPEG-1 or other standards. Given the same capacity of hard disk, Hikvision board leads to longer recording time, thus reduces storage costs and maintenance expenses and improves systematic reliability.

l Ex cellent image quality
Hikvision board adopts variable bitrate coding. It assures constant image quality to different scene and motion picture. Even violent motion cannot bring the mosaic phenomenon. Hikvision board supports real time preview without wobble or time delay.

lPreeminent characters of network transmission
Hikvision board adjust parameter dynamically, which is suitable to assure excellent and fluent image quality in network transmission. It supports CIF, QCIF coding, variable bitrate and variable frame rate. This is more suitable for narrowband transmission, for instance, through PSTN,ISDN,DDN, etc.

lConvenient control
Hikvision boards parameter, such as image quality, frame rate, and sensitive tolerance of motion detection can be adjusted when encoding. It can capture original image. Actively setting parameter is significant in video security.

lFlexible and reliable motion detection
Hikvision board adopts most advanced motion detecting technology whose analytical precision can be adjusted dynamically. It can not only detect micro-motion but also throw away misinformation. Reliable motion detection and video setting reduce storage requirement. The whole detecting procedure is completely done on board. Motion detection is completely independent from compression. It can detect both fast and slow motion.

lConvenient video overlay function
Hikvision board supports flexible title overlay function. It can overlap time on active video with transparent processing. Its location can be adjusted conveniently.

lOutstanding stability and sustainability
Hikvision board adopts encoding algorithm, SDK function and decoding software, which are specially designed for digital video security. All of these make Hikvision board reliable and stable.
