Very impressive, interested to know how the Sonoma County Sheriff's heli made that video?
Looks like a handheld camera, I guess with the NVG component attached as a lens, with a second camera alongside? Or one input, with the image split through a NVG and a normal image processer?
If a proper task, searching for the hikers, why such a high speed pass and a what height over that ridge?
Not condeming the video, it's very impressive and I am gladly awaiting authority for NVG's over here. It just has that "promotional video for the NVG company" feel about it.
