Zeiss DTI 4/35

The ZEISS DTI 4/35 is a thermal monocular camera ("thermal imaging camera"), particularly suitable for hunting observations in densely vegetated forest and field areas. It uses a high-resolution sensor with 640 × 512 pixels and benefits from ZEISS ZSIP image processing for high-contrast, detailed thermal images.

Application Areas / Benefits

Ideal for hunting in dense forests or fields, as the large field of view captures heat sources well.

Thanks to high sensor resolution and ZSIP, very detailed thermal images, even at a distance.

The movement alert function (Movement Alert) is particularly helpful for monitoring animals in a large area without constantly holding the monocular.

Live streaming via the app allows sharing observations in real-time.
