Hi Alex, talk to Sensormatic, the are in Florida, but great folks to deal with.
Don Umbdenstock would be the chap. [email protected] They have a remarkable camera that can sit in the roof and zoom quite hi. While I was at his lab, I didn't see it respond to fields up to 10 v/m. The zoom is remote controlled too. If you were looking for point of use cameras, I have a fibre optic version just a bit bigger than a cigarette case for under $2000. The lenses are C-type, they can be what ever you want. . Cheers, Derek.
