This device comprises at least one sensor (3) consisting of a CCD camera of very short spectral band lying between 0.4 mum and 1.1 mum, fitted with an infrared filter eliminating the spectral band lying between around 0.4 mum and 0.8 mum, this sensor being associated with a computer (4) catering in particular for image processing, at least one display screen (6) and a control board (5). It is thus possible, with the aid of a single type of sensor (3), to detect hot spots, flames, smoke and the shifting of objects, and to provide a visualization of the inside of the enclosure (2).
