The technology mimics the human eye in that it offers high resolution at the centre of the scene. This is achieved using two 320 x 240 pixels uncooled thermal imagers, one with a narrow 5° field of view (140 mm) lens and the other with a wide-angle 20° field of view (35 mm) lens. This combination allows the operator to survey and monitor an entire area without losing any of the detail. The PTZ-35x140 MS accomplishes this with two independent thermal cameras and a unique patented image processing technique that provides both the foveal imaging mode as well as a continuous zoom between the wide and narrow fields of view.

The PTZ-35x140 MS is equipped with a precision Pan/Tilt mechanism, which will increase the area of coverage. Thanks to its precision, fast Pan/Tilt system, the PTZ-35x140 MS allows for easy following of fast moving objects.

The main drawback of traditional long range, dual field-of-view cameras is that when the operator is monitoring an area in a wide field-of-view, this compromises long-range detection. Conversely, when searching in the narrow field-of-view there is tunnel effect that reduces situational awareness and target orientation. The
foveal concept provides the solution as it overlays long range and wide-angle detail and presents it as a single image.

The PTZ-35x140 MS allows full visibility whatever the light level or weather conditions; its rugged Mil-spec/IPX6 enclosure assures reliable performance in harsh climates.

The PTZ-35x140 MS requires no supplementary lighting to operate all year round on a 24/7 basis. Furthermore, the PTZ-35x140 MS is equipped with a low lux daylight camera that can provide complementary low-light color
visibility for additional target identification when conditions permit. Displaying both the thermal image and the daylight image at the same time is also possible.
