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 video archive depth for each camera is calculated every 15 minutes by the Agent of Control.

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

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

Note

An example of calculating the current video archive depth:

Suppose that the following parameters for "Camera 1" 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 = 20.04.2020

Suppose that at the time of the current date 12.05.2020, the video was recorded to the archive on the following days: 20.04, 21.04, 22.04, 28.04, 30.04, 07.05, 08.05. That is, the total archive size = 7 days (the Total, days field).

The size of the current video archive depth (the Current, days field) 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 field).
  • In the date range 04.05.2020 - 12.05.2020 (for the last 9 days), the archive is present only on 07.05.2020 and 08.05.2020.

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