By turning mobile devices into a Crestron Electronics touchscreen, the Mobile Pro Control app allows users to control a range of building systems, including lighting, heating and cooling, audiovisual, and security. It can display room temperatures, shade positions, and lighting levels, as well as stream live video from Web-based security cameras. An open platform allows developers to customize Crestron controls and touchscreen interfaces, which can be transferred to mobile devices. The app is available for use on iPhone, iPad, and Android devices.
