New Firmware Update for the ZEISS DTI 3/35 Thermal Imaging Camera

Improvements to Enhance Performance and Comfort for Hunting at Night

Oberkochen, Germany | 11 August 2021 | ZEISS Consumer Products

A free firmware update will be available in the ZEISS Hunting app for the ZEISS DTI 3/35 thermal imaging camera, which was specially developed for hunting, starting on August 11, 2021. Among other enhancements, the update increases battery life and improves image quality in foggy conditions via the “Contrast Boost” feature. In addition, the new focus frame in PiP (picture-in-picture) mode serves as an important reference guide. “With this update, we are adding important features to the DTI 3/35 that will make the hunting experience even more successful and comfortable,” said Tammo Lüken, Head of Category Management Hunting at ZEISS.

The ZEISS Thermal Imaging Camera - Specially Developed for Hunting

The DTI 3/35 from ZEISS is a thermal imaging camera specially developed for hunting. Thanks to a high-resolution HD LCOS display that delivers detailed images, even in the dark and at night, as well as an ergonomic design, ZEISS offers a specialized solution perfect for difficult lighting conditions.

Better Orientation Even in Difficult Lightning Conditions

"The hunting experience with a thermal imaging camera can be adversely affected by low contrast, especially in foggy or high humidity conditions,” Lüken explains. With this firmware update, ZEISS is enhancing the image processing software so that the contours and edges of animals and plants are easier for the hunter to recognize in challenging observation situations. This ensures that as many details as possible are visible, even in the fog.

Lüken highlighted another challenge during hunting: “It is often difficult to see exactly which part of the main image is being magnified in the ‘Picture-in-Picture’ (PiP) mode. Positioning the image in such a way that the enlarged image is exactly where you want it can take crucial seconds.” To help the hunter more quickly get their bearings in this process, the update adds a focus frame that can now be used to highlight the part of the image that is being magnified via picture-in-picture. “This makes it easier, for example, to track individual animals in a large group and make the decision for or against a shot more quickly. The focus frame thus supports the hunter on his goal towards a successful and ethical hunt,” emphasizes Lüken.

Improved Camouflage and Battery Runtime

In addition to the enhanced PiP function, the update delivers three hours of extended battery runtime for up to four hunts. To further conserve battery power, the DTI 3/35 automatically shuts off after 60 minutes of inactivity.

Lastly, in addition to economical operation, Lüken highlighted the revised camouflage: “It’s important not to create an unnecessary light source that draws the games attention to the hunter, particularly when hunting during the new moon. For these situations, the firmware update now allows the LED indicator light to be turned off, reducing the risk of being spotted by game and making hunting not only more comfortable, but also more successful.”
