Hello, my name is Christopher and I am a computer resource technician at a high school in Colorado, U.S.A. We are using RiseVision on roughly 15 televisions throughout our school, mostly to show a continuous slide presentation to the students. However, some of us would like to expand the capabilities of RiseVision by adding short video presentations with sound during the student passing periods between classes. Since the hallways are usually much to noisy to hear the weak volume on the TVs themselves, my question is, how could we connect the RiseVision platform to our schools separate audio (intercom) system? Thank you. If you would like to respond via email, I can be reached at firstname.lastname@example.org.
