●在线点播内置VOD点播功能，点播时可观看到录制好的各种视频、音频和计算机屏幕内容。

●本地回放通过回显控制模块，实现录制效果本地实时预览，录制文件本地回放，并且实现高清输出。

三.特点●模块化设计，可灵活配置图模块化设计，可灵活配置系统采用模块化设计，支持1路立体声音频输入，支持SD模块、VGA模块、高清DVI 模块、高清SDI模块、回显控制模块的按需组合，单机最多可放入4个模块，支持4路可视信号的任意组合录制、直播和点播（最多可扩展至6路）。

可灵活配置，最大限度满足用户的需要。

支持双平台，按需切换图双平台按需切换支持PowoLive™、BeyondSys™双平台按需切换。

用户可任意选择适合自己应用的平台。

PowoLive™平台，支持Recplayer，支持回显控制模块1，最高支持1080p@60Hz视频、6画面同步录制、直播和点播。

直播延时<0.5s，适合局域网应用。

BeyondSys™平台，支持Windows操作系统、苹果Mac OS操作系统、Internet Explorer 2 拍照功能第一版暂不支持；未来将配合特定行业版本支持。

浏览器、Safari浏览器、Chrome浏览器等多系统、多浏览器，支持自动生成图片索引和在线编辑，使用缓冲播放机制，适合广域网应用。

●1U、19英寸，适合工程安装图适合工程安装相对于其它常见录播一体机动辄4U的庞大体积，REACH CL4000采用自主研发的硬件平台，稳定可靠，功能强大，同时体积大大缩小，仅1U高。

同时采用标准19英寸机架尺寸，适合工程安装。

●灵活多样的管理方式图灵活多样的管理方式REACH多媒体录播一体机支持WEB界面、遥控器（需要回显控制模块支持）、第三方中控3种管理方式，可满足用户各种应用场合下的设备管理需要。
