视频键盘(Joystick) 在CCTV模拟时代起着重要的作用，随着数字技术的发展，模拟键盘也演变为了数字键盘，监控中心用的键盘价格比较高，我们推出了消费级的方案。

XBOX就是一种常用的工具，支持电视墙宫格切换，云台控制(包含预置位调用)，基于摇杆的云台控制使用起来会更方便。

H5S从r18.3开始，USC从1.6开始，直接支持宇视LiteAPI，内置LiteAPI协议，支持实时视频，云台控制和回放。LiteAPI支持Armv8 架构部署，可以在国产系统运行。LiteAPI支持宇视VMS 和宇视NVR。

开发LiteAPI的原因是有些项目的宇视VMS SDK性能有瓶颈，有个别SDK API调用长达10秒钟。使用API的话可以大大提高系统稳定性。
