Overview:
VEC 0404FB video and audio compression card use Texas Instrument's high-performance DSP DM645 with hardware H.264 algorithm compression that reproduces excellent image quality and achieves high compression ratio for the best possible performance. This card can provide 4 channels 2CIF/HD1/CIF/QCIF with 25/30fps and dual-stream encoding; it also can support full channels 4CIF(D1) with 12/15fps or half channels 4CIF(D1) with 25/30fps encoding.
Features:
- H.264 hardware compression algorithm for high compression ratio and excellent image quality.
> 4/8/16 channels 2CIF/HD1/CIF/QCIF or half channels 4CIF(D1) real-time recoding and dual-stream supported, also support full channels 4CIF(D1) non-real time recoding.
> 4/8/16 channels 4CIF(D1)/CIF/QCIF RAW video stream output.
> Support 4CIF(D1)/CIF/QCIF real-time preview for up to 64 cameras.
> Video detection supports Motion detection, Video loss and Video block.
> Support OSD/LOGO overlay, Privacy masking, Frame rate and Bit rate dynamically adjusted etc.
> Provide full SDK with Windows and Linux operation system.
> Compatible with full range of Dahua's Compression card.
