9 Setting Intelligent Analysis Parameters
Table 9-21.
Description
Time interval at which the system checks
for new alarms. The system then reports
detected alarms to the surveillance platform.
NOTE
Only one alarm is reported if multiple times of
video block happen within a single alarm check
interval. This is to avoid repeated alarms.
Sensitivity for triggering an alarm.
A higher sensitivity indicates that an object
with a smaller block size and higher
brightness can be identified. In this case,
lens block alarms can be triggered more
easily.
NOTE
l Sensitivity = 1: An alarm is generated when
the block area ratio is about 95%.
l Sensitivity = 2: An alarm is generated when
the block area ratio is about 90%.
l Sensitivity = 3: An alarm is generated when
the block area ratio is about 85%.
l Sensitivity = 4: An alarm is generated when
the block area ratio is about 80%.
l Sensitivity = 5: An alarm is generated when
the block area ratio exceeds 70%.
