Description
Camping at night you hear something moving beyond the tents. Security patrols cannot see past their torch beams. You are out before dawn and cannot make out shapes in the dark. This helmet-mounted night vision monocular gives 200 metres of night vision on 850nm infrared, which shows only a faint red glow at the lamp, so you see without lighting yourself up. It streams live to an Android phone to share the view or record it, and switches between black and white and fluorescent green for contrast.
