Transition Zoom

Especially when viewing a swarm of birds, it is easy to lose sight of the animal being viewed when jumping the zoom level. Observe your target in 4x magnification, uninterrupted, and without jerkiness – the Transition Zoom allows you to keep a constant eye on the bird you are observing.

Three Observation Modes for Every Situation

Different environmental situations require a different instrument setting. The DTI 1 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.

  • A heron is shown in eight vertical panels, each representing a different imaging or color filter effect, illustrating advanced visual technologies.

    8 Different Color Modes

    ZEISS thermal imaging cameras offer eight 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.

    High Frame Rate

    The ZEISS DTI cameras featuring a display frame rate of 50 Hz. This refers to the number of times per second your monitor can redraw the screen. A higher display frame rate results in decreased flickering of the image, thereby reducing eye strain when using for several hours at a time.

    Picture-in-Picture (PiP)

    The picture-in-picture function of the ZEISS DTI allows overlying the zoomed image on the visual image. This feature helps to keep sight of the animal you are observing in zoom mode, even when it makes sudden movements.

  • A owl is captured in tall grass with a red ZEISS focus frame centered on it. A high-contrast landscape captured in black and white.

    Hot Tracking

    In 'Hot Tracking' mode, the warmest source in the image is framed with a red square. Finding heat sources in densely overgrown areas and tracking them is therefore easier.

    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 DTIs 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.
