Direction and angle of a smoke plume
The inclination angle and direction of a smoke plume are important indicators to detect
smoke. In the field of view of the camera, moving smoke plumes can have a maximum tilt
angle of 90° and will be detected.
Smoke plumes must be visible in the image to be detected by the video-based fire
detection. Smoke plumes moving in the direction of the camera might not be detected as
the movement in the visible image of the camera might look like downward movement.
