Look at it for what it is . Infrared RADIATION . The electromagnetic spectrum consists of visible light, radio waves, x-rays, gamma rays, microwaves, infrared rays and ultraviolet rays. The differences between these radiations are their wavelengths or frequencies.Infrared red waves are emitted by all warm objects. They also heat up the objects on which they fall. When they fall on any substances, the molecules in the substances absorb this energy and get excited and as a result of this, the substance gets heated.
Infrared radiation is emitted by all objects above zero degrees Kelvin (zero degrees kelvin is absolute zero which is -273.15 degrees Celsius or -459.67 degrees Fahrenheit and is the temperature below which all atomic and molecular motion stops).
One of the most effective methods to block IR is to conceal behind glass. Glass is opaque to thermal imaging. It is not a practical solution though, due to the obvious impracticality of carrying around a pane of glass, or constructing your walls and ceiling out of glass .
A simple and effective method to block IR is an ordinary space blanket or thermal blanket of Mylar foil. The foil will block the IR heat signature behind it. A problem though, is that whatever it is that you are attempting to conceal, its heat will either build up inside to an unbearable degree or it will escape somewhere, which will then be visible to IR imagers.
EVEN MORE simply in laymans speach ...... If the sun is up , IR does not work . If its down , it works . Plan your LARGE HOT lights around the sun up/down times . Use ventillated hoods with fans to cool down your heat source quickly . Ventillate your hot spot ( room ) . Also cool down the area you are ventillating into unless it outside . Again keep in mind the suns schedule . 1/2 hour before it sets isnt bad to go off and cool down , 1/2 hour before it comes up to turn everything on . I know in winter months you get like 10 hours good grow light , but hey if your paranoid for a reason . Play it smart .
Another good way to interfere with IR sensing equipment is to counter it with an outside light source .
