Description:Features & Functions : H.264(MPEG-4/Part 10) video compression standard leads to high compression ration and good video quality OggVorbis audio compression standard, with 16kHZ sampling rate and 16kbps output bitrate Real-time video and audio compression, no frame lost 4CIF preview resolution Comply with PCI 2.2 standard , a PC can support up to 64 channels Support WINDOWS 2000/XP and Linux operating system Less than 1 second delay in LAN Setable I. B.P frame sequence Setable video quality and bitrate Setable brightness , contrast , saturation and hue of video signal Support motion detection Support watermark technology Support double encoding Merits of Adopting 4008HC Board H.264 encoding has the advantage of high image quality , low bitrate and low storage requirement, especially suitable for digital video security. 4008HC 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 4008HC board compression ratio is higher than those that adopt MPEG-1 or other standards. Given the same capacity of hard disk, 4008HC board leads to longer recording time, thus reduces storage costs and maintenance expenses and improves systematic reliability. Preeminent characters of network transmission 4008HC board adjust 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 4008HC 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 4008HC 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 4008HC board supports flexible title overlay function. It can overlap time on active video with transparent processing. Its location can be adjusted conveniently. Watermark technique 4008HC board supports real watermark technology so that compressed image file cannot be tampered. Outstanding stability and sustainability 4008HC board adopts encoding algorithm and decoding software, which are specially designed for digital video security. All of these make 4008HC board reliable and stable Specifications: Video Input 8 Channels(PAL/NTSC) BNC(Vp-p = 1.0V, 75O) Audio Input 8 Channels BNC(Vp-p=2.0V,SNR > 83DB,Linear Electrical Level ,1000O) Preview Resolution Resolution: 704*576(PAL),704*480(NTSC) Video Compression H.264, Support CBR, VBR; Frame: 25F/s(PAL)?30F/s(NTSC) Output:32kbps-1000kbps(CIF) or 70kbps-4000kbps(4CIF) Compression Resolution 4CIF:704*576(PAL)?704*480(NTSC) DCIF:528*384(PAL)?528*320(NTSC) 2CIF:704*288(PAL)?704*240(NTSC) CIF:352*288(PAL)?352*240(NTSC) QCIF:176*144(PAL)?176*120(NTSC) Audio Compression OggVorbis, Sample ratio is 16KHz, Output ratio is 16kbps Power Consumption Less than 7W Working emperature -10?--+50?
