Controlling the sensitivity of the fingerprint reader
The bioMetric.threshold
and
bioMetric.threshold.enroll
settings control the sensitivity of
the fingerprint reader in 9000 Series clocks. Both of these configuration settings
default to the normal operations setting of READ_BACK
. These
configuration settings can be found in the settings.conf file of your clock.
On clock start up, the device is initialized to the value specified in
bioMetric.threshold
. Normal operations occur with this
setting.
When enrolling fingerprints, the device is set to the value specified in
bioMetric.threshold.enroll
. This setting can be set to a higher
value to improve the quality of the fingerprint scan during enrollment.
After fingerprint enrollment, The device is set back to the value specified in
bioMetric.threshold
. Normal operations return with this
setting.
