Zeiss DTI 4/35 Thermal Imaging Monocular 

Nature never sleeps. And the passion for observing it doesn’t rest either. Although experienced birders already have a wealth of knowledge, for absolute certainty, the right equipment is crucial. The ZEISS DTI 4 is a thermal imaging camera that always performs at its best. With its compact size, a high-resolution 640 × 512 sensor and ZSIP, it delivers high-contrast, detailed image quality anywhere – even over long distances.

The ZEISS DTI 4/35 is the ideal thermal imaging camera for observing in overgrown and wooded areas. Thanks to the large field of view of 26 meters at 100 meters in combination with its best-in-class image processing quality, the ZEISS DTI 4/35 allows you to detect heat sources in detail even when observing in the most obscured areas.

High detail recognition with 640 x 512 px Sensor

The new 640 x 512 sensor offers higher image resolution for better image quality at all zoom levels, as well as a longer detection range with less noise at the same zoom level compared to a smaller sensor. As a result, it offers more detail detection at greater distances.

Smart Standby for Extended Battery Life

When out in the nature, the nearest power source is often far away. You usually need a portable charger to make sure your device doesn’t run out of power – which means extra weight and equipment to keep in mind. With an impressively long battery life of 7 hours, the DTI 4 models will hold enough charge for two to four birding trips. Extend the battery life even further by activating the smart standby function.

Three observation modes for every situation

Different environmental situations require a different device setting. The DTI 4 has three pre-programmed observation modes: universal, detect and fog. Detection mode, for example, highlights heat sources even more while reducing the cold background. This allows you to see animals behind trees and bushes better than before.

Unique Movement Alert

The Movement Alert tracks the hottest heat source in the image and notifies the user when that heat source moves. The LED on the top of the unit will start flashing or optionally the display will turn on. It is thus possible to monitor a large area without holding the camera all the time.

Customizable Settings

Nature observation can be a very individual activity. When it comes to thermal imaging cameras, every observer has their own personal preferences. Therefore, the new DTI's now offer the ability to select exactly which color modes are active and which are not, so you only must click through the ones you want to use. The same applies to the zoom level setting. Now you can limit the maximum zoom level to your liking.

8 Different Color Modes

ZEISS thermal imaging cameras offer 8 different color modes, so you can choose the setting that best fits your needs. "Black hot" and "white hot" deliver images with a high level of contrast. When observing in areas with vast vegetation, "red hot" allows for a fast detection of heat sources. The color mode "rainbow" is ideal for identifying the smallest differences in temperature. In addition, four color modes have been redesigned to reduce the glare of the screen in a dark environment and reduce eye strain. "Red Hue" mode more easily adjusts your eyes to the darkness. "Dark Hue" is easier on your eyes by using low luminescence colors. "Green Hue" shows plenty of detail at low screen brightness, and "Night Eye" highlights the warmest areas of the thermal image in a pleasant sepia tone.
