Smoke detection characteristics

The algorithm analyzes smoke based on physical characteristics. Typically a plume of smoke is
formed in a regular upward motion of smoke at the same position. This is characterized by a
thick column of smoke. This column of smoke is visible directly. Speed and angle of rising
smoke may vary.
The area in which the smoke density decreases is called ambient smoke. The smoke motion is
not directly visible. Ambient smoke will not be detected.

Smoke will only be detected if the smoke plume has a maximum vertical tilt angle of 45°. The
maximum detectable speed of upward motion is 4.2% of picture height per second.
