Hi Bill,
There are multiple solution sets; I think you need to define your requirements a bit more. For example, is the Polycom output audio loud enough for the room, and you just need a couple of remote wireless mics? The Revolabs HD Dual/Single mics Opens a new window have an analog output that plug into many Polycom phones for a wireless mic solution.
If you're using Skype, how does the Polycom phone come into play with your laptop? Calling in on the Polycom and using the laptop for Skype video and screen sharing? You might go to a USB phone to run off your laptop instead, like the Revolabs UC 500 Opens a new window or the Yamaha YVC-1000 Opens a new window for louder playback and daisy-chained mics for rooms up to 40 people.
For video there are a variety of camera offerings that mostly depend on the type of interface you want to use. Logitech has many types of USB cameras that work pretty well in fixed positions.
For your new rooms you should definitely scope out requirements and nice-to-haves in terms of audio, video, services and wired/wireless. I highly recommend you talk with inside sales or schedule a visit with a field sales engineer. Your guy in the Chicago area is well-versed in audio-visual installations and can really help define your equipment set and services, and perhaps a couple of integrators to check out. It's a free service and can be very helpful if you're not familiar in this arena.
Best of luck!
