Re: Video Gear supplier
In the pro AV world, Canon, JVC, Panasonic, Sony and Vaddio are probably the 'usual suspects' for packaged PTZF camera systems or for separate cameras and PTZ heads. I don't know how long ago you looked at Vaddio but they do have several of their own cameras now and I always found their pricing on the Canon, Panasonic and Sony based products to be competitive. AMX and Crestron still offer pan/tilts and camera controllers that you could use with 'box' cameras or camcorders from other manufacturers. Controllers from the pan/tilt manufacturer or maybe somebody like Telemetrics (also a good source for more complex applications such as moving rail cameras, X-Y systems, remote controlled variable height pedestals, etc.).
There are also a number of lower cost security camera level options including IP based systems, which may be fine for some applications.
