Eyes on More.
In Every Moment.
Upgraded 800*600 OLED display. See the mission, not just the target. The larger display enhances spatial awareness in a single glance.
High resolution, more details
384x288 image display, 15mm detective lens, 50Hz high frame rate and NETD<=40mk provides exceptional clarity and image/video quality.
*GTGUARD H3's using AI resolution tech to gain a 384*288 image with enhanced 256*192 sensor.
Advanced image enhancement technology
DNR (Dynamic Noise Reduction),AGC (Automatic Gain Control), andDDE (Digital Detail Enhancement)ensures smooth, clear video with optimized brightness, contrast, and sharpness, improving object recognition and reducing visual noise for superior thermal imaging performance.
Ultra long detection range
and 8X Zoom
H3 Thermal Imaging detects as far as 1498m away, with 11.69*8.78° field of view, it allows you to spot the heat quickly and stay ahead of the game anytime.
Meet your observation needs
Anytime, anywhere
With 6 unique application scenarios and 5 color modes, you’ll always have a clear, detailed view, no matter the environment.
6 application scenarios
Perfect for spotting birds from a distance, even in dense foliage or at dusk, when other optics might struggle to provide clarity.
For everyday use, providing balanced thermal imaging in a wide variety of situations, from outdoor adventures to casual observation.
Ideal for urban environments, this mode helps you distinguish heat sources among buildings and cityscapes, great for security or search-and-rescue operations.
Highlights the outlines of heat sources against the background for quick identification, making it perfect for navigation or locating people in low visibility conditions.
Designed specifically for dense, humid environments where thermal imaging may be obscured by moisture or foliage. This mode ensures the best performance even in the toughest conditions.
Tailored for dense woods or forested areas, where the terrain and foliage can obstruct clear visibility. Forest mode enhances contrast and helps reveal hidden details.
5 color modes
White Hot
Ideal for general use, providing maximum contrast for identifying people or animals.
Black Hot
This mode is useful for seeing thermal details in bright conditions or at night.
Iron Hot
Ideal for seeing extreme temperature variations in industrial or search-and-rescue scenarios.
Green Hot
Perfect for those who prefer a more natural thermal view with less intensity.
Red Hot
This mode is excellent for quickly distinguishing heat sources in low-light or high-contrast environments.
Highlight the interesting
for you to spot
Immediately focus on the important heat sources. You can accurately identify and track heat signatures in complex environments.
