描述 Description

Support is limited to customers who have already adopted these products.

The TW2819 is a high performance and cost effective multi-channel H. 264 CODEC solution designed for the security surveillance market. It is capable of receiving and encoding maximum 16 channels standard definition (SD) or 960H (WD1) video. It can also support up to 8-channel high definition (HD) 720p or 4-channel 1080p encode. It supports D1/960H/720p/1080p decode also up to 4 channels. Each video channel can be independently controlled in terms of encode/decode mode, frame rate, bit rate.
