6Advanced settings (Detail tab)

Sets the condition to reset the alarm detection timer that measures "Time (sec)" in Alarm conditions on the "Basic" tab, and adjusts the alarm notification operation settings according to your environment.
■Occupancy detection time reset conditions
When the count within the detection area exceeds the threshold, the alarm detection timer starts.
If the timer reaches the time (seconds) set in the “Alarm Conditions,” an alarm is triggered.
The alarm detection timer operates as follows based on the count value:
①
When the count is equal to or greater than the [Count Threshold] in [Alarm Conditions]:

The alarm detection timer starts.
②
When the count is equal to or greater than the “Count Ratio for Timer Reset (%)” and less than the [Count Threshold] in [Alarm Conditions]:
The alarm detection timer is paused.
③
When the count is less than the “Count Ratio for Timer Reset (%)”:
The alarm detection timer is reset.
Here, you can make settings related to the initialization of the alarm detection timer.
[Percentage of people to reset the occupancy detection time (％)]
Select the ratio of the count used to reset the timer for the "Time (seconds)" in "Alarm Conditions."
If the count falls below this ratio, the timer is reset.
　
50％, 60％, 70％, 80％, 90％, 100％
　
Default setting: 80％
[Time to reset the occupancy detection time during pause (sec)]
Set the time to stop the timer when the number of objects detected exceeds “Percentage of people to reset the occupancy detection time (％)” but does not reach “Number of people (person)” in “Alarm conditions”. If this time is exceeded, the timer will be initialized.
　
Allowable time: 0-600 (sec)
　
Default setting: 5 (sec)
■Alarm notification
Set whether or not the alarm notification is notified.
　

Enable: 　The alarm is notified.


　

Disabled: The alarm is not notified.


　
Default setting: Enable
■Alarm notification operation setting
Set the notification operation when the “Count threshold” in “Alarm conditions” is exceeded continuously after the alarm is detected.
　

Periodic notification: 　The alarm is notified at the time interval “Time (sec)” in “Alarm conditions”.


　

Continuous notification: The alarm is continuously notified at the time interval of "Alarm deactivation time" of the camera.


　

One-time notification:　 The alarm is notified only the first time the alarm conditions of "Count threshold" and "Time (sec)" are met.


　
Default setting: Periodic notification
■Human/Vehicle/Bicycle/AI Onsite-learning1-5 identification threshold
Set the threshold for identifying a person's head or body, Vehicle, Bicycle, AI Onsite-learning1-5.
The smaller the value, the easier it is identified, but the greater the likelihood of false positives.
　
Available setting: 1~99
　
Default setting: (head) 30, (body) 25, (Vehicle) 25, (Bicycle) 25, (AI Onsite-learning1-5) 50
■Detection threshold for black and white image
When enabled, the detection thresholds for color and black images can be set respectively.
　
Enable / Disable
　
Default setting: Enable
　
Available setting: 1~99
　
Default setting: (head(black and white image)) 30, (body(black and white image)) 25
■Minimum size of detectable human (pixel) (Human only)
Input the minimum number of pixels (horizontal width) for detection. Assume the image width is 1920 pixels, and detect objects smaller than the pixels you set are excepted.
Available settings may vary depending on the resolution. (E.g., 3840 for a 4K camera)
　
Available setting: 0~****
　
Default setting: (head) 38, (body) 38
■The interval for the transmission of ONVIF
Set the interval for the transmission of ONVIF.
　
5 s, 10 s, 15 s, 1 min
　
Default setting: 5 sec
■Add detection frame information to video data
To add the detection frame information of this product to the stream additional information, set this setting to "On". When using multiple extension softwares at the same time, the size limit of the stream additional information that can be sent by the camera may be exceeded. In that case, set this setting to "Off".
Note that if this product is connected to a system that uses stream additional information, be careful to set it to "Off".
　
Default setting: On
■Saving count data in csv format
To save count data in csv, set this setting to "On". For details, refer to the External Interface Specifications.
　
Default setting: Off

• Count data will be stored for 2 years (732 days).


* In fact, data will be stored for a longer period of time than the above storage time. The excess storage time will depend on the camera's time zone setting (maximum 23 hours).



Example: If the time zone is +9.00


732 days + 9 hours




• The count data immediately before the operation schedule is turned off may not be saved.
■ Object Detection Reference Point
You can select the reference point used to determine when an object has entered the detection area.
The object detection reference point is displayed as a white dot on the settings screen and demo screen of this extension software.
　
Default: Center of bottom edge
■ Apply AI on-site learning improvements for false and missed detections
This menu is only displayed when this product is linked to AI On-site Learning application.
By linking with On-site Learning, it is possible to learn about false positives and false negatives.
This setting item allows you to select whether or not to reflect these learning results in the detection process.
　
Default setting: Off
　

• Adjust the reset conditions of the alarm detection timer according to your environment.


• Truncate the decimal point of (Percentage of people to reset the occupancy detection time (％)) × (Number of objects in Alarm conditions).


For example, if 12 people × 80％ = 9.6 people, then it would be 9 people.




• Please refer to the following table and graph for the mechanism of the reset condition of the alarm detection timer.


This is the example for below conditions.
- Number of objects to cause an alarm : 10 people
- Time to cause an alarm : 10 seconds
- Percentage of objects to reset the occupancy detection time : 80％
 - Time to reset the occupancy detection time during pause: 5 seconds
When the tenth person is detected, after ten seconds the alarm is triggered.
If the number of people detected drops down to eight or nine people, then the alarm will pause.
If the number moves back up to ten with the five seconds (reset time setting), then the alarm state continues.
If the number holds at eight or nine for more than five seconds (reset time setting) the alarm state ends.
If the number of detected people drops below eight, the alarm state ends.
●
Below is the difference in the notification operation between "Periodic notification" and "Continuous notification" in "Alarm notification operation setting".
●
For periodic notification, if the "Time (sec)" of the alarm conditions is shorter than the "Alarm deactivation time" of the camera, the alarm may not be notified at the "Time (sec)" interval of the alarm conditions.
Alarm notification example
　
■Periodic notification
　
(Ex. Time of alarm condition is 10(sec))
　
■Continuous notification
　
(Ex. Alarm deactivation time of camera setting is 5(sec))
