  Material & Technics
     1.  Circuits and device: adopt new and original packing PHILIPS video decode chipset; choose high quality device such as Ta capacitance and SMD-OSC to guarantee the stabilization and layout of the card.
     2.  PCB: optimizing design. Clear audio signal and video signal without disturbing ; much thicker copper layer improves heat conduction largely, it can guarantee excellent heat emission without radiator; connecting finger twice gilding thickness than the one in normal technics, good anti-oxidation, to make device run much longer.
     3.  A / V lines material and interface: 100% copper BNC interface, its stabilization in connection is much better than normal interface’s made by zinc; 30-lines shielded wire video transmission line with high quality; adopt thicker gilding technics in DB connector.
     4.  Quality detection: both card and A / V lines must pass strict detection before on sale.
 Features
    1. Adopt advance H.264 compressiond format.
    2. Adopt latest PHILIPS SAA7134HL Vedio decode chipset.
    3. With 9 bit ADC,better than other 8 bit cards.
    4. With little occupation of system resource and Small HD Space.                                 
    5. Easy to install and easy to use, no need train                                
    6. Software and hardware all have independent intellectual property                                
 Function
        1.  Support multi-cards,with 9004A/9008/9008A/9008E/9008EA can be inserted any together in the same PC.
        One PC support 24 channels(36 channels  if PCI-Express type interface card for SL-9008E/SL-9008EA) video and audio all real-time surveillance and recording at most.
            
        2.  Support more areas, more sensitive (schedule) motion detection recording and sound alarm.         
        3.  Support PTZ control,support perset points and automatic cruise about high speed dome.
        4.  Support multi-grades image quality optional,multi-grades compression format optional. System resources can be better deployed.
             
        5.  Support 16 channels alarm input & 4-8channels output with alarm I/O card(optional) and linkage camera recording
        6.  Support recording frames adjustable: 1-30fps(NTSC) / 1-25fps(PAL)
        7.  Support static pictures capture when display or playback.
        8.  Support display full screen, minimum screen and screen lock.
        9.  Recording format optional: audio and video compression at the same time or only video compression.
      10.  Perfect user administering and detailed log recording.
   11.  Video shielding function; administrator can set some important locations to be unauthorized. Then even if  the videos are  recorded, users cannot see or playback the relative videos.
             
      12.  Multi-channels playback at the same time easily and playback authority management.
      13.  Support LAN and remote IE browse, listening, recording, playback, remote playback and PTZ control.
      14.  Low-power design, reasonable structure of card, stable system.
      15.  Software need not be registered, free upgrade.
