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 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):
The specification parameters are displayed in the following columns:
- Number of servers—the number of servers recommended for the specified number of cameras.
- Server platform—platform name and, if detection tools using the GPU are specified, links to GPU selection (see Types of detection tools). When you click on the link to the GPU selection, the documentation pages with the performance data will open.
- Server CPU load—CPU load as a percentage.
Server RAM, GB—the recommended size and number of RAM modules for dual-channel operation, taking into account the number of processors on the platform. For example, “4 x 8GB” RAM means two 8GB RAM modules per processor for a dual-processor platform.
Info title Note RAM should be used in dual-channel mode or greater mode based on the number of processors in the platform. For example, at least 2 RAM modules must be installed for single-processor platforms, and at least 4 RAM modules for dual-processor platforms.
Using RAM at a higher frequency, or using RAM in dual-channel mode or greater mode results in CPU load decrease, and therefore in the performance increase.
- Server storage configuration—required configuration of the disk subsystem, in particular:
- Actual archive size and required HDD marked capacity for storing the archive if No RAID calculation was chosen, or actual archive size if RAID level was chosen.
- Recommended RAID configuration if RAID level was selected:
- total number of disks per server,
- disk size,
- number of RAID groups,
number of hotspare-disks.
Info title Example 28x 4 TB (2x RAID-6 + 1x HS) means 2 RAID-6 groups with a total of 27 4 TB disks and 1 hotspare-disk.
- The SSD volume required to store metadata and system log.
- Required storage recording rate—total recording rate which must be supported by the disk subsystem of the server.
- LAN (in/out)—total rate of the video streams from IP cameras, to be provided by the bandwidth of the network interface of the server.

If 100 cameras are added, and as a result of recommended platform calculation, it is recommended to use 5 servers with 50-60% server load, this means that it is required to use 5 servers and install 100/5 = 20 cameras on each server. In this case the CPU load of each server will not exceed 50-60%. |

The calculation is based on the results of testing the corresponding GPUs (see GPU performance for Axxon One detection tools).

For a Server with viewing, it is sufficient to use an NVIDIA GeForce GT520 / Intel HD Graphics 530 graphics card (integrated into a 6th generation Intel Core processor) or a higher-performance GPU.
