Not to add to the paranoia, but but if you want to foil the security cameras, you’re going to need IR blocking hardware. Regular sunglasses won’t even foil your iPhone…
This is because your iPhone, as well as most security cameras all have an infra red viewing mode so they can function in low\no light conditions. This feature punches it right through your traditional non-IR blocking sunglasses.
Why, you may ask… Facial recognition software uses nodal points to determine who it’s looking at. It needs a minimum number of these to satisfy the algorithm and complete “recognition”.
These nodal points (also known as fiducial points) are:
- Eye corners (inner and outer)
- Eye pupils
- Nose tip and nostril configuration
- Mouth corners and lip contours
- Eyebrow endpoints
- Chin
- Ears\Earlobes
I went back and looked it up. Kolari Shades makes the best glasses for this purpose. They’ll set you back somewhere between $250.00-$350.00US, but they will block 90–99% of infrared light and 100% of UV light. Reflectables will get you closer to $200.00US and will block around 95% of IR light.
As far as the rest of your head, you have three options. IR light emitting, reflecting and absorbing. Your call, but the IR emitting variations are not as effective, either in cost or effectiveness compared to the absorbing and reflecting variations. Balaklavas are very effective, but suspicious to human eyes. Hoodies are the stealthiest in general.
The bright spot, no pun intended, is that IR facial recognition software does not react or respond when it finds itself blocked. It just fails to identify without triggering an alert.
Ni Dieu ni maître
