Merits of Adopting  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:

Save storage space

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

Excellent image quality

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

Preeminent characters of network transmission

AVH board adjust parameter dynamically, which is suitable to assure excellent and fluent image quality in network transmission.  It supports 4CIF, DCIF, 2CIF, CIF, QCIF coding, variable bitrate and variable frame rate.  This is more suitable for narrowband transmission, for instance, through PSTN、ISDN、DDN, etc.

Convenient control

AVH board’s 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.

Flexible and reliable motion detection

AVH 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.

Convenient video overlay function

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

Watermark technique

AVH board supports real watermark technology so that compressed image file cannot be tampered.

Outstanding stability and sustainability

AVH 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
