Camera Archives

Images retrieved by a Camera Archive Logic Element are going to be saved in a camera archive which is located in the SDMODULE. Before this is possible, the storage space reserved for camera archives and the camera archives in it must be configured.

You can find the configuration interface for camera archives at System > Settings > Camera Archives.

SDMODULE

The upper half contains an overview of the current storage allocation status of the SDMODULE. A pie chart represents the total storage space of the SDMODULE. It is divided into the following segments:

• Reserved space:
  storage space reserved for camera archives

• Free space:
  storage space in the SDMODULE which is neither used nor reserved for camera archives. Important: This is not the same as the actual free storage space in the SDMODULE

• Space used by others:
  storage space in the SDMODULE already used for something other than camera archives

Settings for Reserved Storage Space

The total storage capacity of the SDMODULE as well as an input field for the storage space reserved for camera archives can be found beneath the pie chart. The reserved space can be set as either MB or GB values. The upper bound for this value depends on the status of the free space available in the SDMODULE while the lower bound equals at least the space used by all images contained in every camera archive.

Archives

The lower half of the configuration interface offers an overview of all camera archives. Camera archives are defined by their percentage share of the storage space in the SDMODULE which was reserved for camera archives. This means that the absolute storage capacity of a camera archive is derived from the reserved storage space in the SDMODULE.

Another pie chart shows how the reserved storage space is allocated among camera archives. For each camera archive its percentage share, absolute storage capacity and the storage space already used by images are shown.

Settings for Camera Archives

To add a new camera archive klick the "Add camera archive" button. A modal dialog appears, which contains input fields for these parameters:

• Name:
  Identifier for selecting an camera archive for both Camera Archive Logic Elements and CONTROL L - Visualizations

• Share of reserved space:
  Integer percentage value for the share of the reserved storage space in the SDMODULE. The lower bound is 1% and the upper bound equals the current unallocated share

• Action on storage depletion: Behaviour of the camera archive when its storage is depleted. There are two available options

  • "Stop":
    No more images will be stored in the camera archive once its storage is full

  • "Delete":
    Delete the oldest 10% of all images in the camera archive to free storage space for new images

New camera archives can be added as long as there is unallocated space availble. In order to add camera archives when 100% of the reserved storage space is allocated you either need to delete camera archives or decrease their shares. 

The settings of each camera archive can be seen in the table beneath the pie chart. You can change the percentage share of a camera archive through the input field in the middle.

Important: The percentage share of a camera archive cannot be changed to a value which is less than the percentage share of the reserved space taken by the images in it

Deleting a Camera Archive

A Camera archive can be deleted vie the trash button in the table. Then a modal dialog will appear listing all Logic Groups containig Logic Elements which use this particular camera archives as its target. These Camera Archive Logic Elements should be changed or deleted first to avoid unwanted behavior in the affected Logic Groups and error messages on the dashboard.
