嵌入式分机：分机安装方式为暗装，首先将分机的预埋底盒埋墙安装，再将分机固定在预埋底盒上。嵌入式分机安装后与墙面基本高度一致，对于室内整体视觉效果非常好。另外由于嵌入式安装分机有比较大的空间，可以加载比较多的扩展功能；其缺点为需要暗埋底盒，施工难度比较大，并且在安装后不容易进行移动。
Embedded extension: the installation mode of the extension is concealed. First, install the embedded bottom box of the extension on the wall, and then fix the extension on the embedded bottom box. After the embedded extension is installed, it is basically the same height with the wall, which is very good for the overall indoor visual effect. In addition, because the embedded installation unit has a large space, it can load more extended functions; its disadvantage is that it needs to bury the bottom box, the construction is difficult, and it is not easy to move after installation.
