The Dahua M20 Thermal Imaging Monocular captures sharp thermal imaging at a fast frame rate for smooth, impeccable vision on running targets and from moving vehicles. Designed to increase situational awareness at any time of day, M series can detect humans, animals, and objects in complete darkness, haze, or through glaring light, equipping law enforcement professionals, hunters, and outdoor enthusiasts with reliable thermal imaging in tough conditions.
Designed to be precise, this thermal camera produces vivid video images through its enhanced detector and Dahua-developed image processing algorithm. With its hassle-free distance measurement feature, simply mark the top and bottom of a target on the screen, and the interface will automatically display the distance of the target from the monocular.
Multiple phones can connect to the monocular through the Wi-Fi at the same time. Through the mobile phone, you can watch the live view, capture images, record videos and configure parameters. By adjusting the diopter adjustment knob, the thermal camera can be set to match the eyesight of different users, ensuring that each user sees a clear image.
