The HS-X6400 is a monocular handheld with interchangeable lens. Using a 640 x 480 thermal imaging core, it provides four times the image clarity and detail of earlier systems, allowing officers to see more of their surroundings than any other night vision technology in the world. Depending on the lens mounted on the camera, vehicles can be detected at 2414m (with 35mm lens), 4667m (with 65mm lens) et 5954m (with 100mm lens). That model has a 4X digital zoom.
