The application allows automatic reading of laser rangefinder values and ambient temperature, as well as manual setting of object emissivity and ambient humidity values to correct temperature measurement results.

What is the main strategy of the Zenmuse H30T sensor burn protection function?

The H30T will automatically close the shutter when it detects conditions that could cause IR sensor burn-in. However, software detection may fail. Do not point the lens of the infrared thermal imaging camera toward high-energy sources such as the sun, lava or laser beams. Otherwise, it will burn the camera and cause irreparable damage.

What the infrared density filter on the Zenmuse H30T is used for?

Expands the temperature measurement range of the thermal imaging module to 0° to 1600° C (32° to 2912° F), enabling more efficient evaluation of temperature changes and quick location of high temperature points. When the IR density filter is installed, IR signal reception is reduced, which also degrades image quality. Not suitable for observing objects at normal temperature and is recommended to be used in low gain mode.

Zenmuse H30/H30T visible light camera - frequently asked questions

What is the Night Scene mode in Zenmuse H30 series?

Improves image quality in low-light conditions, presenting clearer and more accurate visual information to ensure efficiency and precision during nighttime operations.

How night scene mode has improved in H30T compared to H20N?

The H30T's night scene mode allows adjustment of 25 fps./s, 15 fps./s and 5 fps./s at a maximum sensitivity of ISO 819,200, offering improved noise reduction and support for NIR illumination.

Why in Night Scene mode, higher levels of noise reduction reduce the smoothness of live broadcasts?

Higher levels of noise reduction result in lower frame rates, longer exposure times and higher sensitivity, as well as better noise reduction performance. However, due to the reduced frame rate, the smoothness of the live video is reduced accordingly.

What is the electronic haze removal function of Zenmuse H30 series and how to select the intensity of haze removal?

Electronic haze removal is an image processing technique designed to reduce image blurring and haze effects caused by light scattering, atmospheric moisture and other factors. Uses computer algorithms to optimize and restore images, increasing clarity and quality. Electronic low-level haze removal is mainly designed for use in mild haze conditions, while electronic high-level haze removal works well in situations such as post-rainfall fog and moderate haze.

Can I enable electronic haze removal in Night Scene mode?

Not. Electronic haze removal is for use in daytime haze, while Night Scene mode is for use in low-light conditions at night. Both require image processing, but due to different application scenarios and purposes, their effects will conflict, so they are not supported simultaneously.

Why electronic haze removal is only supported by a zoom camera?

Varifocal cameras usually observe objects that are farther away and more susceptible to rain, fog and haze in the air. Therefore, electronic haze removal is primarily intended for a camera with a zoom lens.

What is the maximum zoom supported by the zoom camera when taking high-resolution grid photos?

Maximum zoom supported during grid shooting is up to 15× zoom.

What is smart capture mode and what are its main application scenarios?
