Hardware requirements

Computer requirements

The POS PSIM software package requires the same computer configuration as the Axxon PSIM (base) software package; see the Axxon PSIM Software Package: The Administrator’s Guide document.

Operating system requirements

The POS PSIM software package requires the same operating system configuration as the Axxon PSIM (base) software package; see the Axxon PSIM Software Package: The Administrator’s Guide document.

Video camera requirements

The POS PSIM software package requires the same video cameras as the Axxon PSIM (base) software package; see the Axxon PSIM Software Package: The Administrator’s Guide document.

POS-terminal requirements

We recommend creating no more than 200 POS-terminal objects (see The POS-terminal object setup procedure) on one computer to ensure fail-free system operation. 

MS SQL software should be installed on the same computer as the POS-terminal objects.

Define required disk space (receipts database size)

Disk space required for storage of receipts database can be calculated by the following formula:

Required disk space, GB = N (pcs.) * K (items/hr) * T (days) * 24 (hrs/day) * 2.4 (KB) / 10242 (KB/GB)

Where

N is a number of objects generating events;

K is an average number of items per object per hour. It can be estimated experimentally in operation conditions.

T is an archive depth in days set while system configuration.

2.4 KB is a disk space required for storage of one event.

Example. Let us have 75 objects, each of them processes 1 item in 5 seconds (~720 items per hour). Archive depth is 90 days, 16 hours per day.

Required disk space, GB = 75 (pcs.) * 720 (items/hr) * 90 (days) * 16 (hrs/day) * 2.4 (KB) / (1024*1024) (KB/GB) = 177.98 GB ~ 180 GB
