Merits of Adopting 4004HC Board
H. 264 encoding has the advantage of high image quality, low bitrate and low storage requirement, especially suitable for digital video security. 4004HC 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
4004HC board compression ratio is higher than those that adopt MPEG-1 or other standards. Given the same capacity of hard disk, 4004HC board leads to longer recording time, thus reduces storage costs and maintenance expenses and improves systematic reliability.

Excellent image quality
4004HC board adopts variable bitrate coding. It assures constant image quality to different scene and motion picture. Even violent motion cannot bring the mosaic phenomenon. 4004HC board supports real time preview without wobble or time delay.

Preeminent characters of network transmission
4004HC board adjusts parameter dynamically, which is suitable to assure excellent and fluent image quality in network transmission. It supports 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
4004HC board 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
4004HC 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
4004HC board supports flexible title overlay function. It can overlap time on active video with transparent processing. Its location can be adjusted conveniently.

Watermark technique
4004HC board supports real watermark technology so that compressed image file cannot be tampered.

Outstanding stability and sustainability
4004HC board adopts encoding algorithm and decoding software, which are specially designed for digital video security. All of these make 4004HC board reliable and stable
