The term ‘sensors’ when used in low-light covert surveillance, can denote many technologies, that being
Night Vision refers to a sensor that utilises an Image Intensifier (Tube) to magnify the available ambient light into a ‘workable’ image. The Image Intensifier is incorporated into the camera/sensor focal plane to provide high resolution low-light imaging.
Thermal Imaging refers to cameras/sensors that utilise a Thermal Detector as the image gathering device. The Thermal sensor detects the ‘heat signature’ of the target.
Night Vision & Thermal Imaging sensors each have their benefits & drawbacks
Kit such as the (DANOS) Day & Night Observation System incorporates Image Fusion technology, which fuses both the Night Vision & Thermal Imaging images together as an overlay, providing the operator with the benefits of both technologies.
