I came across https://www.reflectacles.com/. I’m not sure if this type of gear is effective. Does anyone have experience or feedback on useful equipment for mitigating scanning in public spaces?

    I didn’t read into the specifics of the IR LED they are using, but assuming it’s somewhere in the 850-900nm wavelength with sufficient power, they should be blocking you out if the CCTV is recording infrared images.

    There’s a video here that explains the principle. I’ve highlighted the key part, but feel free to check out the whole thing to understand the idea: https://youtu.be/fywvB4Unjv4?t=240

    Thing is, if the camera records in the regular, visible spectrum only, it will see you just the way you are. Most cameras automatically switch to IR mode when the environmental light strength drops below a certain threshold, so you’d be “invisible” at night, but clear as day during, well, daytime.
