FLIR Scout III 240 Thermal Imager Review


Thermal imaging is used to detect infrared radiation and thermal energy to collect information about things and classify their images, even in low-visibility conditions. Thermal imaging is a type of technology that has developed a wide range of applications over the years.

Specifically, this is a great form of night vision technology, capable of working in the entire absence of any light, and can even operate in smog, haze, smoke, and fog.

The thermal imaging technology is extensively used to detect humans during surveillance or military operations at nighttime. Besides, search and rescue responders and other firefighters with heat sensors may search for peoples those who are trapped behind the rubble or smoke.

In modern days, FLIR is one of the world leaders in the manufacture, design, and marketing of sensor systems or thermal imaging cameras, which enhance the perception and awareness of a wide range of users in industry, commercial, and government markets, internationally and domestically.

This brand produces various products for conditional surveillance, research & development, aerial observation & broadcasting, search and rescue (SAR), and surveillance & intelligence.
