描述
Support is limited to customers who have already adopted these products.
TW2809C is a high performance and cost effective multi-channel H. 264 codec solution designed for security surveillance market. It is capable of encoding and decoding maximum 8 channels standard definition (SD) video in real time. It can do high definition (HD) 1080x60i encode or decode at real time too. Each video channel can be independently controlled in terms of encode / decode mode, frame rate, bit rate, and resolution. TW2809C is an ideal H. 264 codec candidate for different DVR platforms such as 16CH SD or 16CH CIF
