Had an installation of an Extra Small SMART LRS this has a single 55” display designed for smaller meetings rooms. On SMART website it state four people but you can get more people in the room depending on the layout.

Here’s a couple of difference i found when comparing against the larger models with 70 and 84” displays.

• Much smaller display quite noticeable when using whiteboard
• Ideal for smaller meeting room spaces
• Console PC is not installed in the display but installed is a caddy fitted to the wall behind the screen.
• Input Source is HDMI1 / USB1 needs setting to HDMI1
• No Lync Room reset available when using the remote
• Separate Power supplies are used for speakers and camera attached to the back of the screen
• Camera has a bracket fixed to the top of the screen and is attached with single screw to the bracket.

Overall is a good system for smaller meetings room but if you can get the Small system with 70” display i would go for that model or bigger if you can 🙂
