As a writer, I find Quora invaluable. Check out this amazing question and answer: perfect for Thriller writers:
Are there any technologies to prevent yourself from being captured on camera or video
There actually is an easy and cheap way you can prevent yourself from being captured on video or CCTV. Most cameras especially black and white security cameras will see low levels of infrared light. This helps them video at dusk/dawn and in lower levels of light. The level of light the camera can see is called the LUX level. To test this theory turn on your video camera and point your TV remote control at it. Change a few channels and you will see a pulse of light flash that the naked eye obviously cant see. With that said you can easily make an infrared hat with cheap $1 infrared LEDs stitched into the front of the hat, the more the better… Attach a 9 volt battery to the LEDS and bam you are now a giant LED flash light. People will see nothing out of the ordinary, but CCTV cameras will only see a large flash of infrared light coming from your head, hiding your face.
