PI technology and hot tracking
The thermal imaging camera comes with cutting-edge PI technology, which uses special software to render sharp, detailed images so that you can identify objects with ease. There is also a practical hot tracking mode, which automatically highlights the warmest object.

Detection range
Featuring an NETD value of 40 mK, the infrared thermal imaging sensor enables you to detect objects from far away. For example, you can detect wild boar at a range of up to 1000 metres, even in complete darkness. 

Six different colour palettes
Different scenarios present different challenges in terms of image rendering. For this reason, the TNS3 thermal imaging camera offers a total of six different colour palettes to choose from: Rainbow, red-hot, white-hot, black-hot, wildlife observation mode, and yellow hue.

High frame rate
The Wi-Fi thermal imaging camera has a frame rate of 50 Hz, allowing you to observe moving objects in crystal-clear quality.

Long battery life
The thermal imaging camera comes with a built-in rechargeable battery, which lasts for up to 6 hours after a full charge.

The TNS3 thermal imaging camera is particularly suitable for wildlife observations and hunting expeditions. However, it is also very useful in other scenarios involving sources of heat. For example, it can be used to locate geothermal heat sources and thermal leaks in homes and apartments.
