Theon Teos-W Wrist-Worn Thermal Sensor for Threat Detection in VBSS and CQB Operations
Technical specifications
Technical overview
The Theon Teos-W is the wrist thermal sensor designed for the boarding operator (VBSS), the assault shooter in CQB, or the person tracker in nighttime search-and-rescue who needs heat detection in total darkness without diverting hands from the weapon to operate an additional device — the Teos-W attaches on the back of the operator's tactical glove or on the forearm via the included MOLLE-glove mounting system, and projects the real-time thermal image to the 0.3-inch integrated monocular-type viewer on the unit, accessible with a wrist turn without releasing the weapon.
The 320×240 pixel uncooled microbolometer detector with 50 mK NETD sensitivity captures the body temperature difference of a person (37°C) against forest or structural background (ambient temperature), generating a 60 Hz image that the integrated image processor converts to the selected palette — Hot White, Hot Black, Ironbow, or Rainbow — with automatic scene gain adjustment that adapts contrast in 80 ms when the operator moves from cold exterior to hot compartment interior without bloom. The 19 mm optics with 60-degree field of view provides a cone of vision similar to the human eye without obstructed peripheral vision for operation in narrow ship spaces.
The USB-C rechargeable lithium battery integrated in the body provides 8 hours of continuous operation, or 20 hours in low-power mode with wrist movement activation, covering the full surveillance shift of a watch or the complete nighttime boarding operation from start to finish. The total weight of 95 grams on the glove does not induce perceptible wrist fatigue in 4-hour operations according to Theon's ergonomic studies, and the distributed weight balance prevents barrel deflection when moving the wrist to firing position.
