Can sunlight reflection induce infrared noises to a filtered webcam?
Dear askmehelpdesk members,
Recently I want to set up a system so that my webcam will only detect infrared (940 nm) from only my infrared LED and nothing else, using 940nm-allowed-only filters.
In case I really need to do this in a place with plenty of strong sunlight, do you think sunlight reflection from shiny rings and/or shiny metallic table surface can potentially induce noises to my webcam? Do you think that through adjustments of threshold (the level of voltage considered valid) and exposure level of my webcam, I can potentially reduce COMPLETELY ALL sunlight reflection noises, but still detect my infrared LED?
Any quick opinions please. Thank you so much.
