<div> 视频分配器把多路完全独立的视频输入信号分配成多组视频输出信号。经分配输出的每一路视频信号的带宽、峰-峰值电压和输出阻抗与本组的视频输入的信号格式相一致。1U标准机柜和桌面两用机箱。视频分配器可将一路视频信号转变成多路信号，将一个影象信号分配给多个接收源，输送到多个显示与控制设备。</div>
<div> 一般是一路视频信号对应一台监视器或录象机，若想将一台摄象机的图象送给多个管理者查看，最好选择视频分配器。由于并联视频信号衰减较大，送给多个输出设备后由于阻抗不匹配的原因，图象会严重失真，线路也不稳定。视频分配器则可以实现阻抗的匹配，还有视频信号增益，使视频信号可以同时送给多个输出设备而不受影响。</div>
