After adding cameras to the list (see Selecting cameras), the types of detectors can be specified for platform calculation with or without view (see Selecting the type of calculation). You can select several detector types for each stream. The list of available detectors depends on the selected software platform (see Selecting the software platform). The detectors cannot be selected to calculate the platform for the operator's workstation.

See the detectors description in the corresponding subsection: Types of detectors for Axxon One or Types of detectors for Axxon PSIM.

Add detectors as follows:

1. Click the button in the Video Analytics column. 
   
2. The detector selection form is displayed. The detectors are grouped by type on several tabs (1) and by the processor used for operation (central or graphics) on each tab (2):
   

3. To select a detector, left-click its name. You can select detectors from several tabs. The selected detectors are highlighted in blue.

   The current version of the calculator supports GPU calculation only for one detector on GPU in the whole configuration (no limit for CPU). If you add several detectors on the GPU, the calculator will not let you save the selected detectors and will require you to remove extra detectors on the GPU or replace them with the ones on the CPU.

4. As a result, the selected detectors are displayed in the Video Analytics group.

   Click the button next to the detector name to deselect it.

5. When you finish selecting the detectors, click the Apply button. The detector selection form is hidden:
