b) that IR LED would have to be extremely powerful to overwhelm a camera that is looking at a larger area
- tinus_hn 6y agoYou could send something like the macrovision signal that hinders the automatic exposure correction.
- nitrogen 6y agoThe Macrovision signal was an out-of-image voltage change during the blanking interval. AGC circuits in VCRs that used the blanking interval to set the gain would be thrown off by it. So unfortunately it is not something that can be displayed meaningfully in visible light. But, maybe you could find a different flaw in the exposure control. If not, you'll just have to be really bright.
- 01100011 6y agoI'm thinking more along the lines of covering yourself or your immediate area in a collection of randomly flashing IR LEDs. It's not about blending in, it's about defeating current CCD cameras. Obviously it is just going to attract attention to you when 'sensor fusion' becomes more prevalent. It's for when you want to appear as a glowing ball of light on a surveillance feed and not have your face or gait captured.
