In Light Of The Current Political Situation, Here Are Some Helpful Hints: "How to defeat infrared night vision and Thermal Imaging"

Thermal imaging:can be very intrusive/dangerous should you wish to go for a nighttime stroll with a Predator circling over your head.

Night Vision 

The surveillance technologies enabling image capture in little to no lighting are intensified, infrared (IR) and thermal imagery. Let’s take a closer look.

 Intensified Amplifies Existing Light


Technology advances in the past 20 years have resulted in great improvements to the performance of how well intensified CCDs pick up images in low light. 

The first area of low-light systems open for discussion is known as the intensified charge-coupled device (ICCD). 

This method of night vision amplifies the existing light. It focuses the existing light on the photocathode of an intensifier. The light causes electrons to be released. These electrons are then accelerated by a high voltage (about 15,000 times); the accelerated electrons are focused onto a phosphorous screen. The energy of the electrons makes the screen glow, which in turn is received by a CCD sensor producing a video image. 

Technology advances during the past 20 years have resulted in great improvements to the performance of intensified devices. Their ability to identify people and objects at very low light is its major advantage. ICCDs also offer high resolution or detailed images in extreme lighting environments. However, ICCDs do require some existing light in order to function. Intensified CCD cameras also produce a poor daytime image when compared to day-only cameras. 

So what do we do if there is no existing light available? 

IR lighting is one possible solution. 

IR Works With No Visible Light 

IR lighting is a light source designed for black-and-white cameras or the new day/night switchover surveillance cameras. It is incorporated for extremely low- or no-light applications. This light source has little or no effect on the spectrum of light that the human eye uses to produce an image. Therefore, applications where video is required but the use of visible light is prohibited are cases in which IR light is extremely helpful. 

IIR light can be split into three categories: Near-infrared (near-IR) — Closest to visible light, near-IR has wavelengths that range from 0.7 to 1.3 microns, or 700 billionths to 1,300 billionths of a meter....
