The Thermis is Theon Sensors' handheld thermal camera for tactical observation in conditions where conventional night vision is insufficient: fog, smoke, dense vegetation, and static camouflage. Unlike NVG systems that amplify visible and near-infrared light, thermal detects the long-wave infrared radiation emitted by body heat — making camouflage, vegetation, and complete darkness irrelevant as limiting factors.

The 384×288 pixel uncooled VOx (Vanadium Oxide) detector with 17 µm pitch requires no cryogenic cooling time: the Thermis is operational in less than 5 seconds from power-on, versus 3-5 minutes for cooled detector systems. The NETD <40 mK thermal sensitivity allows detecting temperature differences of less than one-tenth of a degree, sufficient to identify recent footprints in the ground or detect camouflaged machinery by its residual thermal signature hours after it has stopped.

Key features

Uncooled VOx detector: operational in <5 seconds — no cooling wait time
NETD <40 mK: detects residual thermal signature of stopped machinery and ground footprints
Penetrates fog, smoke, and dense vegetation where NVG loses effectiveness
H.264 video output for recording and transmission on tactical data network
4x digital zoom for long-range detail designation and recognition
>8 h autonomy — internal battery without requiring additional field batteries

Applications

01Observation and reconnaissance in fog, smoke, and vegetation — where NVG fails

02Camouflaged personnel detection: body thermal signature cannot be camouflaged

03Industry: hot spot detection in electrical substations and machinery

04Nighttime search and rescue: person location by thermal signature

05Border control: illegal crossing detection in complete darkness
