M40 captures sharp thermal imaging at a fast framerate for smooth, impeccable vision on running targets and from moving vehicles. Designed to increase situatonal awareness at any tme of day, M40
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 conditons.
Advanced Image Processing
Designed to be precise, this thermal camera produces vivid video images through its enhanced detector and Dahua-developed image processing algorithm.
Video Ranging
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.
Fire Detection
Fire detection is now available for the first time with this monocular through Dahua's core technology. The monocular can automatically detect fires that break out in the scene and track them in real time.
Simultaneous Multi-user Connections
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.
Diopter Adjustment
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.
Laser Eye Protection
The laser pointer is used to indicate a position. To protect the eyes from being injured, the laser pointer is automatically disabled after 10 s.
Portable and Low Power Consumption
With its small and lightweight design, it functions for longer periods while remaining fully charged, making long-term outdoor use more convenient.
