This does not work for FR that does not observe IR. Which is most FR systems, because most FR systems have to use legacy video hardware several years, often a few camera generations, back. Including wholly optical CCD systems.
However, a similar fashion accessory does an even better job: some fashion hats have blinky LEDs on them; blinky LEDs cause a camera's components to adjustment for the unusually bright light, which are then gone, than back again. The mechanism in most security cameras cannot adjust for the lighting changes as fast as the LEDs are blinking, causing no good captures of the face beneath the blinkly LEDs.
- lakechfoma 8y agoDon't a lot of image sensors pick up infrared? I don't have any IR remotes to test modern stuff with, but I know my Galaxy S5 and every phone and point and shoot camera I had before that would register the light from IR remotes. I guess that's a cheap filter away from being fixed anyway.
- bsenftner 8y agoSure, lots of image sensors pick up IR. But they are not in the millions of legacy security camera systems at banks, grocery stores, college, corporate and campus security systems. The majority of the surveillance systems of the world are 10-20 years old. they work fine, for their original purpose, and the owners want to add FR, not purchase an entire new system requiring the loss of their previous investment.
- subway 8y agoSay what? All those legacy systems (probably) shipped with a weak IR filter, but the CCD on the the devices will more than happily react to a bright IR light. This is even how the majority of "night" cameras operate. They ditch the IR filter, then illuminate the scene with IR.
- lakechfoma 8y agoYeah this is what I was getting at. How many old cheapo security cameras have no or bad IR filters if that was still the standard for ~2012 flagship Android devices...
