6mm Operators got a comparative review of two scope cams for airsoft from RunCam and Foxeer... "A true comparative between both "Airsoft Edition" products from Runcam2 and Foxeer2. Run away from other reviews showing only footage against a dark background, those ain't no true field tests.

Here you'll see these products taken to their limits with footage of shooting against direct sunlight, over a yellowish vegetation background."
