4 channel input capture card 1704HC

CCTV capture card 1704HC supports 4 channel video input and 4 channel audio input, H.264 video compression. Supports CIF video and audio real time and synchronous coding in one chip with 8 channel. Adopted with PHILIPS PNX 170X series chip, this capture card's main frequency is twice of PNX150X series chip.

Features:

* Unique video converging and transmitting chip.
* Advanced motherboard-self-adapt technology is adopted in this series of capture cards, it supports various chipset motherboards and display cards, it exerts the function of motherboard, and effectively reduces the trouble in selecting motherboard.
* The SDK software is with user friendly interface.
* This series of capture card have high cost-effective.
* Mostly 64 channels of encoding could be supported in one PC, in other words, 4 pieces of 1716HS capture cards or 8 pieces of 1708HC capture cards are supported in one PC.
