Good quality photo/video cams have IR block filter as IR in sunlight causes focus/colour problems. Night vision cams omit such a filter or use a movable filter. During day or with other lights active they don't need their own illumination but otherwise they need their IR LEDs. If close, IR LEDs present a corneal hazard as arrays can output >4000 W.m^-2, the t > 1000 s limit is 100 W.m^-2, but with low retinal sensitivity there's no natural mechanism to gauge/limit exposure. | |
