Each gas has its own absorption spectrum and presents typical absorption peaks in infra-red bands II (3 to 5 µm MWIR) and bands III (8 to 14 µm LWIR). Second Sight operates in band III, in order to use the particular peaks to enable the identification of a vast majority of gases. The Second Sight measurement principle uses the scene background as an infra-red source, and image processing algorithms to highlight the presence of a gas cloud in the line of sight.

In the event of an alarm, the presence of a gas cloud is displayed as an overlay on the infrared image. The identification and estimated path length concentration are given in the top left corner and the gas is underlined in red in the gas list.

The latest version of Second Sight is becoming a universal gas detector with its new detection algorithm Gas X, an unknown gas detection capability that enables the detection of any gas cloud modifying the infrared signature in band III of the observed scene, even if the gas is not listed in the system’s database.

Vehicle mounting

The vehicle mounting is a mechanical interface to easily attach the head camera with its pan & tilt on the roof of any vehicle.

GPS option

The GPS coordinates of the Second Sight is given in the Graphic User Interface. It highlights the area of surveillance on a map. Integrated with a compass, it also gives the direction of the Second Sight when used with Pan & Tilt.

Battery

Lightweight and compact battery designed with lithium-ion technology to offer 5.5 hours of autonomy

12° objective

Specific lens for surveillance up to 5km. This lens is compatible with any Second Sight and can be replaced by the user
