Some people prefer to use a PC as their main home controller.
One advantage of this is the availability of many powerful software programs featuring voice control, speech output, phone control, Internet access, and much more. HomeVision-PC was designed for this purpose. This makes it a perfect choice for users who want to use PC software to control their home. They get all the capabilities as the standard HomeVision, but at a lower cost. HomeVision-PC can currently work with HAL2000, Home Voice, ECS, MASS, or HomAtion 2000 software, or you can write your own software to control it.
