Thanks Eric, I have not heard about the bluetooth cameras and any related issues. I wonder if the fps works there as well. It is hard enough for me to get access to Macs and that's half the reason I made the class.
I initially chose 1.5 seconds for each camera and so far almost all cameras I have tested have come out of their initial init phase before 1.1 seconds. I don't have a lot of experience with a lot of cameras so if you say FW cameras tend to be really slow maybe I should change the default for a bit longer, but there are properties in the class so you can tell the object how long it should check for. I put those in for exactly the reason you are describing. Some cameras take longer, and if the developer using my class wants to test each camera for a longer period of time he has the ability to. Thanks for the feedback.
