Allowed Color
When configuring helmet detection, you can set allowed colors. When
the helmet detected is not in the selected colors, alarms will be
triggered.

When events not following the rule are detected and the duration
exceeds the defined value, alarms will be triggered. For example, when
the duration of helmet detection is 5 seconds, if the Device detects a
person not wearing helmet or the helmet color is not allowed for more
than 5 seconds, an alarm will be triggered.
