General information about detectors and their sub-detectors

By default, the Axxon One distribution package includes only the basic DetectorPack (see Installation, Installing Axxon One in Linux OS).

To install add-ons to the basic package, do the following:

  1. Download the required packages from the official website.
  2. Stop the Server (see Shutting down a Server).
  3. Run the executable file and wait for the installation to complete.
  4. Start the Server (see Starting a Server).

Versions of the basic DetectorPack and the DetectorPack add-ons must be the same. If versions differ, you must update the version of the basic DetectorPack, so it matches the version of the DetectorPack add-ons.

All packages of the DetectorPack with detectors and their sub-detectors are described in the table:
