Frequently Bought Together



See the heat with the Thermal Monocular Camera. Rather than visible light, thermal cameras use different levels of infrared energy or heat to create an image. This allows it to easily detect people, animals, and objects in all kinds of environments, including complete darkness, haze, or glaring light.
