When comparing conference call systems, look at camera resolution, field of view, pan-tilt-zoom and optical zoom capabilities, plus features such as automatic framing, speaker tracking, and multi-camera support for larger rooms. For audio, compare integrated or modular microphone options, noise reduction, voice-leveling, and speaker placement, along with systems that support multiple mic pods and dual speakers when a room needs broader coverage.

Conference call systems connect to video conferencing platforms through a built-in mini-PC with a preloaded Zoom Rooms or Microsoft Teams Rooms application, or through USB connections that support compatible conferencing applications. They can also integrate with existing AV equipment such as displays, speakers, microphones, cameras, table hubs, and display hubs, while some larger-room systems use an AV processor for multi-camera layouts.

Plan for power, a compatible display, network access, and the cabling needed to connect the camera, speakers, microphones, room console, and mini-PC or video bar. Choose a system that matches the room size and conferencing platform, and account for wall or table mounting, cable routing, and added audio devices when the selected package does not include speakers or microphones.

A conference call system can scale to larger rooms through modular audio, with additional speakers and microphones placed throughout the space; some configurations support up to seven mic pods. For extra-large rooms, multi-camera systems with an AVHub can coordinate panoramic and close-up views, while separate room kits support small-to-medium, medium-to-large, large, and Pro AV spaces as needs grow.
