They could pulse the LED quickly and while it's off use it as a light sensor for ambient light.

- DistractionRect 3y agoProbably this. Doing so would allow one to check for agreement between the video feed and the light sensor.
- schroeding 3y agoI wonder if one could just replace the LED with a UV one, depending on the tolerances this kind of detection may still work while being visibly "off". :/
