| 室内机在原理设计上有两大类型，一类是带编码的室内分机，其分支器可以做的简单一些，但室内分机成本要高一些；另一类编码由门口主机或分支器完成，室内分机做得很简单。彩色室内分机的液晶屏到2014年还没国产化，成本较高，这是制约彩色可视楼宇对讲系统应用的瓶颈。 There are two types of indoor unit in principle design, one is the indoor unit with code, and its branch can be done simply, but the cost of indoor unit is higher; the other is done by the door host or branch, and the indoor unit is very simple. The LCD screen of the color indoor extension has not been made in China by 2014, and the cost is high, which is the bottleneck restricting the application of the color visual building intercom system. 对讲分机的外观类似于面包电话机，趋向于多样化。可视分机方面趋向于超薄免提壁挂，但流行最多的仍是壁挂式黑白可视分机。室内分机在楼宇对讲系统中占据成本较大，从发展来看，以带安防报警、信息发布的彩色分机在高档楼盘中应用较多，中档以黑白可视对讲分机居多，低档配套为对讲分机。 The appearance of walkie talkie extension is similar to bread telephone, and tends to be diversified. The visual extension tends to be ultra-thin and hands-free wall mounted, but the most popular is still the wall mounted black-and-white visual extension. The indoor extension occupies a large cost in the building intercom system. From the development point of view, the color extension with security alarm and information release is widely used in high-grade buildings, the black-and-white visual extension is mostly used in the middle level, and the low-level matching is the intercom extension. |
