If you’re talking about normal video surveillance, I think most of today’s cameras use regular light. These sunglasses would be effective against a biometric scanner, the iPhones depth camera, a Windows Hello screen unlock or an XBox Kinect. But the average camera on the street uses visible light and likely has an IR filter in place (at daytime), so it won’t even see infrared.

What works against these are ski masks, wearing a motorcycle helmet… Or even large hat or golf hat, depending on the camera’s perspective.
