6. Outline Min Object Size on the camera view, and select Max Object Size from the drop-down list
and outline it on the camera view.
7. Select Sensitivity. The higher the value, the more sensitive the system is for changes in the
camera view.

10. In the Options section, configure these settings:
„ Automatically Disable Alarm: Stops all types of triggered alerts, including computer alarm,
flashing boxes and output module after the specified duration. Disabling the alerts will not
disable alert settings and the detection in progress.
„ Embed Alarm Region into Recorded Video: This option will contain the flashing alert boxes
in the recorded files so that you can easily spot suspicious events during playback. Note that if
you are used to searching suspicious events with Object Search, do not enable this option.
These flashing boxes can cause false alarms.
„ Skip Instant Light Change: Ignores sudden illumination changes and avoids false alarms.
For example, light switches can cause illumination changes suddenly. With the option
selected, the system will ignore significant illumination changes without triggering the alarm
and continue monitoring. See the Note in Crowd Detection earlier in this chapter for possible
risk.

„ Never Recycle: With the option selected, the system will not recycle the event files of
unattended object detection.
