Patent ID: 8754942

Claim:
A detection device ( 1 ) for detecting fires and/or signs of fire in a surveillance region comprising: a camera device 6 for monitoring the surveillance region that includes one imaging sensor element ( 2 ) designed to output image data and an optical device ( 3 ) installed upstream of the sensor element ( 2 ), an evaluation device ( 8 ) designed to detect fires or signs of fire in the surveillance region by evaluating the image data, wherein the optical device ( 3 ) is disposed and/or designed such that the viewing field ( 4 ) of the camera device has a maximum viewing angle (α) of at least 120° in at least one plane that is coplanar to the direction of observation ( 5 ) of the camera device ( 6 ); wherein a central and/or middle region ( 14 ) of the viewing field is hidden optically and/or via programming, and has a viewing angle of at least 30°; and wherein the range of the depth of field of the camera device ( 6 ) starts at a distance of at least 1 m; and wherein the central and/or middle region ( 14 ) of the viewing field is concealed to eliminate interfering factors therefrom during processing by the evaluation device ( 8 ).
