VIO G1
Why It Performs

Multi-Feature Capture in One Turret

EO, thermal, and ranging in a single lightweight gimbal — with AI tracking and a complete control interface.

4K EO Zoom

A Sony block camera with 20x optical zoom (up to 240x combined) captures crisp 4K@30 video and 8.51 MP stills for long-range observation.

Radiometric Thermal

A 640×512 uncooled thermal core with ≤ 50 mK sensitivity and full radiometry overlaid on the live video, with an athermal 19 mm lens.

2400 m Laser Rangefinder

An eye-safe 905 nm Class 1 rangefinder ranges to 2400 m with 0.01–0.5 m precision — plus pinpoint target geolocation and geotagging.

AI Tracking & Detection

Basic and smart object tracking plus AI detection of cars and people — expandable to more object classes via software updates.
