Masking
Due to the different areas of application of the camera, false alarms may be the result in
individual customer environments. Algorithm disturbing elements which have an appearance
similar to flames and smoke, for example ascending steam of a machine, must be excluded
from the detection area.
Customized areas can be defined in the picture of the camera. These individual masks for
flame and smoke detection deactivation allow individual adaption to the application of the
customer. Overlapping of masks is possible.
There are several possibilities to exclude picture areas from the smoke and flame detection:
–

Automasks support the user to adapt the system to his individual application area. Once the
camera is powered, every upcoming alarm will be stored into the volatile alarm memory.
Generally it is advantageous to wait a certain period of time before using the automasking
feature for the first time. It depends on the special customer environment, whether there will
be false alarms or not. With automasking, detection disturbing areas in the picture can
automatically be masked out by the system. If there is no alarm, no automask will be
generated. The user can change the size of the automasks to minimize the masked out area.
The system is limited to 16 automasks (8 masks for smoke detection and 8 masks for flame
detection). Changes of the flame and smoke detection settings require renewing the
automasks.
Add mask
You can define individual areas (16 in total) in which the detection can be deactivated or
modified. These masks can easily be added to the picture area.
