Creating a report of average number of people in time interval

In order to create a report of average number of people in time interval, do the following:

1. Select the Average number of people in time interval type (see Selecting a type of reports by People Counter detector section).
2. As a result the dialog box for specifying the report parameters will be displayed.
   

Set the following report parameters:

1. In the Detectors field set checkboxes in those People counter objects information on which should be displayed in the report (1).
2. Specify the period in the following way:
   1. From the Receiving data period: drop-down list select the time period for which the report is to be created (2).
   2. If the User defined period is selected, enter the date of start and end periods for which the report is to be created in the from and to fields using the Calendar tool. Click the  button near the corresponding field to use the Calendar tool.
   3. If the User defined 2 period is selected, enter additionally the time of start and end periods for which the report is to be created using the  button.
      If another period type is selected, specifying the date of start and end periods is not needed.

3. Enter a time period (in minutes) during which the values received from people counter detector will be averaged in the Step field (3). The average values of people amount for the specified interval are displayed in the report.

   Note.

   If the average value is null the empty report will be displayed for such intervals for the specified period. It is recommended to change the step in this case.

4. In the Max value field specify a maximum value of people that will be displayed in a chart (4).

5. From the Time zone: drop-down list select time zone by which report is to be created (5).

   Note.

   Time zones created in the Intellect software package which have only one time period and haven't got any inclusions are available to select. Selection of week days is not performed. Detailed information about creation and using of time zones is presented in the Creating and using time zones section.

6. If it is necessary to view a report as a chart, set the corresponding checkbox (6).
7. In the Layout field, select the print layout of the report: Portrait, Landscape (7). 
8. Set the Sum results: checkbox to display sum result by selected detections in the report (8).
9. To create a report click Execute (9).

Procedure of working the people counter detector for creation the report of average number of people in time interval is follows:

1. The basic data are events about enter and exit sorted by time.
2. Do the previous calculations to create the "Number of people at a time" function:
   2.1 During the specified period the "current number of people" in the zone is calculated at a time. Depending on the people entering or exiting the basic data is increasing or reducing by one.
   2.2 If the "current number of people" takes the negative value on the next step (the number of exiting people from the area is more than number of entering people to this area), the "current number of people" is set to zero. Also, the "current number of people" is set to zero every day at 2 a.m. (on default) or after the time (in minutes) past midnight specified as PeopleCounterZeroPointMinute key in C:\Program Files\Intellect\Modules\Wt2\Web.config file.
   For example, the string
   add key="PeopleCounterZeroPointMinute" value="60"
   means that the people counter is set to zero in 60 minutes past midnight.
   2.3 It there are no events about entering or exiting to the defined time, the "current number of people" remains unchanged.
3. For every interval calculate the average number of people being in the area. "Average number of people for the interval" is calculated as the average value of "Number of people at a time" function at a time.

As a result a report of average number of people in time interval with specified parameters is displayed.
