hy-1708HC

117 series HC DVR card is the first one in China to develop CIF video and audio realtime and synchronous coding in one chip with 8 channel.

2This DVR card adopted with PHILIPS PNX 17?? series chip, its main frequency is twice of PNX15?? series chip.

3Video converging and transitting chip of this series of DVR card is totally researched and developped by HighEasy, and has been registerred as patent.

4Advanced motherboard-self-adapt technology is adopted in this series of DVR cards,it supports various chipset motherboards and display cards,it exerts the function of motherboard,and effectively reduces the trouble in ??ing motherboard.

5The series of DVR cards are compatible with any kind of hard encoding cards manufactured by HighEasy. The SDK software is with good interface definition compatibility. To run the DVR, Human-machine performance software is need to replace the SDK file and ?? the driver program.

6This series of DVR card have high cost-effectivity.

7 Mostly 64 channels of encoding could be supported in one PC,in other words,4 pieces of 1716HS DVR cards or 8 pieces of 1708HC DVR cards are supported in one PC.
