To display information on archives, select an object and click the  (Info on archives) button.

As a result, the information on the archives of all cameras of the selected object will be displayed in a new window.

The information on archives includes:

Number — video camera number.

Camera — video camera name.

Threshold, days — required archive depth on video camera. This is the Keep archive for (days) parameter specified in the Partition of Control settings.

Current, days — current archive depth.

Total, days — total archive size for all time.

Period, days — the period for which the archive is monitored. If the archive is monitored for all time (the default setting of Agent of Control), then this value equals to 0.

Occupation, % — fullness of the archive in percent. The parameter is calculated by the formula: the number of days from the oldest archive entry to the current date, in which the archive exists, divided by the number of days from the oldest archive entry to the current date, and multiplied by 100.
If the archive was not recorded at all, then the parameter Occupation, % = 0. If this value is close to 100%, then there is no empty space in the archive.

Connection — video camera connection date.

First record — the date of the earliest record in the archive.

Last record — the date of the latest entry in the archive.

Alarm — indication that the current archive depth does not meet the requirements. If the archive is in an alarm state, then it is highlighted in red.

An archive alarm is generated when the following two conditions are met simultaneously:

  • Current video archive depth (Current, days column) < Keep archive for (days);
  • ("Current date" - "Camera connection date" (Connection column)) > Keep archive for (days).

Loop — a sign that the camera is recording on the loop. 

The Agent of Control calculates the size of the video archive depth for each video camera every 15 minutes.

Note

An example of calculating the current video archive depth:

Suppose that the following parameters for Camera 1 object were set when the list of cameras was configured (see Configuring the camera list):

  • Keep archive for (days) = 7
  • Gaps in the archive (days) = 1
  • Camera connection date = 04/20/2020

Suppose that at the time of the current date 05/10/2020, the video was recorded to the archive on the following days: 04/20, 04/21, 04/22, 04/28, 04/30, 05/07, 05/08. That is, the total archive size = 7 days (the Total, days column).

The size of the current video archive depth (the Current, days column) is calculated as follows:

  • In the date range from (Current date - X) to Current date, the search is performed for days on which the archive was recorded, where X is the number of days = Keep archive for (days) + Gaps in the archive (days) + 1. In the current example X = 7 + 1 + 1 = 9 (the Period, days column).
  • In the date range 05/02/2020 - 05/10/2020 (for the last 9 days), the archive is present only on 05/07/2020 and 05/08/2020.

Thus, the video archive depth for the Camera 1 object = 2 days (the Current, days column).

Size of the current archive occupancy (Occupation, % column) for the Camera 1 object is calculated as follows:

Total, days * 100/(Current date - First record + 1).

7 * 100/21 = 33%.
