Each time the streams are added to the list (see Selecting cameras), or the parameters affecting the calculation are changed (bit rate, streams recording, etc.), the parameters are recalculated.
Archive and disk for metadata size
The Total video archive size section shows both the size required for the video archive and the HDD marked capacity—the recommended hard drive size. In this case, it is taken into account that hard drive manufacturers use multiples of 1000 when designating capacity, while the real hard drive size is calculated in the binary system as a multiple of 1024. For example, if the HDD capacity marked by the manufacturer is 1 TB, then in fact 0,91 TB will be available for the video archive.
The Dedicated SSD for metadata and system log section shows the volume of the SSD required to store the metadata and system log. This information is displayed only for the Axxon One platform if data storage was enabled in the settings (see Archive and metadata storage parameters).
Total streams
The Total streams field contains the values for the total stream from IP cameras, stream for recording and stream transmitted to clients, calculated for the specified cameras:

The bitrate values used for streams calculation are for informational purposes only. For an accurate calculation of camera bitrate, use the camera manufacturer's calculator. |
Recommendations
Recommended platforms
The The Recommended platforms tab of the Result of calculation section shows the results of platform calculation for processors with the selected architecture (see Selecting the CPU architecture):
...
You can add an alternative platform to the calculation—for details, see Adding a platform for calculation by analogy.
Recommended GPU models
If a one or more GPU-based detector was detectors were selected for video analytics (see Types of detection tools (Video Analytics)), then recommended GPU models will be listed below the table with recommended platforms:
The calculation is based on the results of testing the corresponding GPUs (see GPU performance for Axxon One detection tools).
The columns indicate the specification parameters:
- Number of GPU items.
- GPU model name.
- Percentage load of SM (Streaming Multiprocessor) computing cores.
- Percentage load of hardware decode chip (NVIDIA NVDEC).
- Amount of required GPU memory in megabytes.
...
Features of filters displayed above the table:
- GPU filter—this is the basic filter for graphics cards. You can enter the model name partially or fully, for example:
- Custom filter allows you to select specific GPU models for different detection tools. To do so, set the required checkboxes in each detector's tab and click Apply Filters:
Specifics:- If all checkboxes for any detector are clear, it will be equivalent to selecting all checkboxes.
- To discard current changes, click the Cancel button.
- The Reset button restores the filter to its default state: all GPUs are selected for all detection tools.
- Different GPU Models per combination limits the maximum number of unique GPU models in the recommendations. For example, if a 1 value is set, then no different GPU models are combined in each recommendation; while a 2 value allows combinations of up to two different GPU models in each recommendation. The possible range is from 1 to 5, a default value is 1.
Specifics:- If there are insufficient benchmark results for GPUs to generate recommendations, an empty table with the message "Unable to calculate. Try to increase number of different GPU models" is displayed. In such cases, it is recommended to increase the combination value in the filter.
- If the number of combinations is large, calculation time increases, resulting in an empty table with the message "The calculation will take a long time. Reduce the number of selected GPU models or the number of different GPU models." In such cases, it is recommended to decrease the combination value in the filter.
Features of the recommended GPU models table:
- Recommendations are grouped by the number of GPUs and their resource load parameters. Cards with the same resource load parameters are displayed within one group.
- You can expand each recommendation by clicking on it—a table with details will open.
- In the expanded table, the selected detection tools and their quantity are listed, along with GPU core load in percentage, decoding chip load (Nvidia NVDEC) in percentage, and the required video memory in megabytes.
- The TOTAL row shows the combined resource load values of the graphics cards.
In the example below, four Nvidia Quadro P2200 (5GB) cards are recommended, and two of them are grouped together (2x Nvidia Quadro P2200 (5GB)):
