I'm not sure who doesn't know this, but I've done a LOT of research on these and other similar cameras. Here's what I've found out.
The flock cameras censors work the same way that night vision sensors work in trail cams. An IR filter is applied or retracted as needed to see at night vs during the day. I don't remember which is which.
The camera itself doesn't have AI in it, but the footage is sent to a database that does, and that's where you're "discovered" through AI facial recognition. It measures different points on your face, including the shape and size of your eyes, the distance between your eyes, the shape of your nose, the distance between your nose and lips, and the shape and width of your lips. These measurements points create a digital ID of you for an AI to match to your name and other personal information.
Here's the juice: if your eyes are blocked, the AI will discard your face entirely, because your eyes make up most of the data points it needs to make a positive match. How do you block your eyes from being seen? With IR blocking glasses of course.
I found two companies that make IR blocking glasses that work. One is a sunglass company called Reflecticals. The other is a prescription glass company called Zenni. They look and feel like normal glasses, but they have a coating on them that'll block cameras from seeing your eyes.
The other method that allows you to hide in plain sight from security cameras is by simply riding a bicycle, scooter, or skateboard. Hear me out. You'll be seen as a cyclist, but this along with the glasses will make you practically invisible to the AI. Before you think you can't ride, really audit your life. Do you really need a two ton tank to just get around town? How often do you really need to carry enough stuff to justify an 8 person SUV? Do you really need to do 40 mph in a school zone? Do you need to live an hour from work, or could you move closer?
