Zeiss DTI 3/25 GEN 2 Thermal Imaging Camera are the next step up in the DTI series, and replace the original DTI 3/25. The sensor remains the 384x288 but the display improves to a 1024x768 AMOLED display for improved contrast and color fidelity resulting in a sharper, clearer image. Four new color modes were added increasing the total to eight for all DTI models.

The DTI 3/25 Gen 2 has an optical magnification of 1.7x and 4x digital zoom that goes from 1.7x to 6.8x in .5x steps. The field of view is 780' at 1000 yards. The DTI 3/25 G2's 17 µm pixel pitch means that each pixel in the sensor is more sensitive than those of the DTI 1 models.

The DTI 3/25 Gen 2 has a built-in Lithium-ion battery that has a 8 hour life per charge, which is done by USB cable. The USB connection can also be used to download photos and videos or run off of an external power supply. Internal memory is 32 GB. The DTI 3/25 G2 is also 2.4 GHz WiFi IEEE 802.11 b/g/n capable and can provide streaming images to cell phones with the Zeiss Hunting app installed.

  • Movement Alert a flashing LED tells you when the hottest heat sources move.

Zeiss Smart Image Processing

Thermal images are typically dark and have difficulty separating warm temperatures from cool ones, resulting in a low contrast image. You can see this in the "Undesired Image" below. The Zeiss Smart Image Processing (ZSIP) software optimizes the thermal image to improve contrast and distinguishable detail into a "Desired Image".


Color Mode Comparison

All DTI models now have eight available color modes which can be chosen via the menu. Each color mode has advantages over the others, some in contrast, some in lowering eye fatigue, and some in finding the thing you're looking for.
