A thermal imager is a camera which is capable of detecting extremely small temperature diff erences. These temperature diff erences can be converted into a real-time video image. Displayed on a monitor, this video image is extremely suited for night vision applications. Unlike other night vision systems that require low amounts of light to generate an image, a thermal imager needs no light at all. This makes it the perfect tool to see in absolute darkness, to see during the darkest night.Thermal imagers are very eff ective for securing large open areas. Thermal imaging is invisible to intruders, allowing security personnel to monitor their actions without their knowledge, protecting people and assets before they are exposed to danger.
