We used to use a small Logitech USB camera/mic and the built-in speakers on the TV. The upgrade to the MeetUp was very noticeable and highly recommended. We were very impressed with the build quality of the device and the camera's ability to tilt and pan is quite impressive.
Smaller conference rooms with room for about 4-6 people seems to be a sweet spot for [Logitech Meetup]. They also work well in smaller rooms where people need to move around and might use a whiteboard or something similar. Once you have a longer room or anything outside of what Logitech recommends, it still works, but the quality quickly drops and you're much better off with adding the microphones or opting for one of the other systems designed for bigger rooms.
While the other cameras offer similar solutions, we found for the price to features, the meetup met our needs the best. With the trio, we had issues with Poly's software which the meetup gets around by being able to plug directly into a PC. The panacast, while it worked very well, we would have still needed to pair it with the rest of the equipment for a full experience. With the meetup, we have only needed the meetup, the PC, and an iPad as a controller.
