I would be happy to add my thoughts. Just a question or three to clarify;
When you say "Wireless" do you mean Wifi or 2.4ghz digital transmitter to a receiver? or are you asking about (cordless) battery operated or some combination?
What is the use case?
Is there any requirement that the cameras connect to a particular VMS?
Feel free to reply here or email me diectly if you prefer firstname.lastname@example.org
Iffy on how helpful this comment will be - but the Blackhawk Imaging (formerly Scallop Imaging - acquired by Vision Technologies) cameras (180 degrees, etc..) had a very pleasant, unique look to them-- not like a camera at all really. I had them in our lunch area as we were running tests.. I asked several employees (for kicks- not for a formal survey) if they could pick out the camera. None of them could.
Great look, great coverage and images. Might be worth a look. I'm sure John has written some more about them on IPVM that can provide more info. Cheers.

You said wireless, so I assume you mean IP based cameras, as opposed to stand alone/edge recording cams. Do you know how you will power these cams? Have you told your client that WiFi based cameras are less reliable and easy to disrupt? I could theoretically disable your cameras from a distance by blasting your building with interfering signals, blocking out your WiFi.
