You’re going to be able to greatly minimize your exposure to physical surveillance by following most of the recommendations in this book; however, this is a frequently changing environment, so you will have to be diligent and adapt. I didn’t say be paranoid or run for your life, just be aware of surveillance that is undertaken around your daily activities and be pro-active about taking steps to minimize or eliminate (defeat) that surveillance.
I have seen lasers used to “dazzle” security cameras before but they normally use visible light and need pinpoint accuracy to be effective. I had never thought about using an array of IR LEDs (infrared light emitting diodes) to create a permanent result that would not be noticeable to anyone else around. http://alan-parekh.vstore.ca/ir-led-5mm-p-67.html

“IR.ASC is an infrared light – to the device before Divining infrared surveillance cameras. There is no special technical knowledge of each reconstructed. The device emits infrared light from the infrared images from surveillance cameras disturbs. The face of the person is monitored by a light ball over. Since the whole interaction in a non-visible spectrum (at frequencies between 780nm and 1mm), the man noticed nothing of it and he sees neither the infrared emission of radiation surveillance camera nor by the IR.ASC “
