 Compared with the DS-4000H and improve the performance increase 
 Low power consumption, making the system run more stable; 
 In a compression card 8 can be achieved up to CIF resolution real-time encoding (DS-4008HC); 
 Provides a more flexible configuration, you can 4 CIF coding and 1 channel 4CIF coding switch back and forth between; 
 Compatible SDK interface makes development faster, easier; 
 Theoretical support for a 64-way PC audio input, each channel can be encoded in real time, fully independent adjustable control parameters.
