Introduction CO-4000C series cards are top-quality hardware compression cards with the most advanced H.264 video compression algorithm and OggVorbis audio compression technology. These cards support real-time preview & recording for each channel, and recording and preview video with QCIF / CIF / 2CIF / DCIF / 4CIF resolution. CO-4000C series cards utilize a fully optimized algorithm based on DSP technology to implement video & audio real-time encoding and motion detection, significantly saving computer processor resources. Model CO-4004C: 4 video and 4 audio input, 100 F/S (PAL) or 120F/S (NTSC) CO-4008C: 8 video and 8 audio input, 200 F/S (PAL) or 240F/S (NTSC) Outstanding features * Support up to 64 channels real-time preview & recording in one PC, due to hardware DSP processing instead of CPU * With advanced H.264 technology, experience 40% higher image quality and over 60% of saving on recording storage space Main functions * Each video channel can be compressed independently in 25F/S (PAL) or 30F/S (NTSC). Both variable bit-rate and variable frame rate are supported * Each audio channel can be compressed independently, using an OggVorbis audio standard. The output bit-rate is 16 kbps * The output video and audio streams are integrated to generate the synchronized H.264 stream. Video and audio coincide with each other from beginning to end when the stream is played back * Real-time display resolution: PAL:4CIF (704x576) NTSC: 4CIF (704x480) * Real-time recording & playback resolution: PAL:4CIF (704x576), DCIF(528x384), 2CIF(704x288),CIF(352x288), QCIF(176x144); NTSC: 4CIF (704x480), DCIF(528x320), 2CIF(704x240),CIF(352x240), QCIF(176x120) * Supports dual stream mode, ensuring fluent network transmission * Supports multi-zone motion detection * Supports position configurable OSD & LOGO * Supports digital watermar * Supports partial zone sheltering * Supports independent configuration of video quality and frame rate for each channel * Supports independent configuration of brightness, contrast, saturation and hue of Video signal for each channel With H.264 technology, users will experience the following benefits: * Up to 40% higher image quality * Over 60% savings on recording storage space * Truly "Live" performance despite variations in network transmission conditions
