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
