Abstract: Device (1) particularly for detecting and potentially identifying at least one target inside a determined volume (V), the device (1) comprising an image acquisition system (2). The image acquisition system (2) comprises, —at least one infrared camera (3) that is sensitive to waves with a wavelength between 780 and 1400 nm, —a thermal camera (4) that is sensitive to waves between 3000 and 14000 nanometers and —a camera (5), referred to as visible, that is sensitive to waves between 350 and 780 nm. The cameras (3, 4, 5) are mounted on a common support (6) in the form of an elongate, beam-type body. The cameras (3, 4, 5) are arranged on the common support (6), with the fields of view of the cameras (3, 4, 5) having an intersection area (8) that corresponds to the volume (V) to be observed. The optical axes of the cameras (3, 4, 5) arranged on the common support (6) are not aligned and the distance (D) between the optical centers of at least two of the cameras (3, 4, 5) is between 10 cm and 2 m.
