Powerful Audio/Video Server for Your Telemedicine System


MediaLink IV is the fourth generation in ProConnections’ line of bi-directional audio/video servers. MediaLink IV allows you to utilize an existing or new speaker, microphone, and camera that can be easily connected to industry standard I/O connectors. The server is built utilizing ProConnections’ state-of-the-art audio/video technology and provides easy integration as part of a  comprehensive telemedicine system.


Over 11,000 ICU and critical care patients rely on MediaLink servers as the audio/video component of the remote monitoring system. Its sharp video processing can continuously monitor and adjust quality levels based on available bandwidth. Clear, wide band stereo audio provides the acoustic separation needed to help remote clinicians distinguish voices in busy room environments. And, built-in multi-conferencing support means there’s no need for additional multi-conferencing hardware or services.


  • Highest quality of audio and video.
  • Supports both standard definition and high definition video.
  • Easy-to-use standalone client software,
  • Allows for remote control of a PTZ (pan/tilt/zoom) camera.
  • Fully configurable and adaptable to your telemedicine system components.
  • Multi-conferencing capability that can support four-way video conferencing between on local (patient) and three remote streams (medical care providers) without additional hardware.
  • Available SDK for integration with existing software packages.
