Warning!
Bosch Security Systems assumes no liability for the reliability of fire detection in case of
configuration changes in Expert Mode. This means it is your responsibility to ensure the
reliability of the fire detection and, if necessary, perform fire tests.
In some applications with different lighting conditions, it is necessary to adjust the standard
settings, e.g. lighting by sodium lamps. These lamps generate a yellowish light in the image
area and can impair the algorithm and flame detection. This chapter contains advanced
settings options for your application.
Change either in the Configuration Manager or in the web browser menu under
Configuration > Camera > Installer Menu > Application variant from standard mode to
Expert Mode.
7.4.1 General lightning settings
Go to Camera > Installer Menu > Day/Night. You can select the following settings:
Auto - the camera switches the IR cut-off filter on and off depending on the scene
illumination level. Select this setting if you have continuous natural or artificial light in your
application and at last 1 lx are available or you have artificial light and redundant IR
lightning.
If the illumination is lower than 1 lx, the camera switches to monochrome mode. In this
mode, it may take longer until a reliable flame detection is possible.
Monochrome - the IR cut-off filter is removed, giving full IR sensitivity. Select this setting if
you have continuous IR lightning in your application.
Color - the camera always produces a color signal regardless of light levels. Select this
setting if you have continuous natural or artificial light in your application.
There are three different settings in the camera menu that are important for lighting in
relation to video-based fire detection:
