3.2.11 Remote access
Usually the generated data is sent to a central server in a remote location by protocols.
This server will then perform data analytics. But these data protocols did not include a
remote access e.g. for first setup or maintenance. The sensor itself in a shop behind a
router and behind IPv4 NAT and firewalls is not accessible for a service and maintenance
PC.
To solve this, we recommend a Virtual Private Network (VPN) that is shared by the sensor
and the PC and a VPN service server. This VPN connections are like an additional virtual
network with additional IP addresses in this network. The VPN connections are built up as
secured encrypted tunnel thru standard networks as Ethernet including the Internet.
To start with this, we have a small demo server package, that could be used e.g. on a vir-
tual machine (VM) with Ubuntu 18.04 to handle your list of sensors and service PCs.

As software inside the sensor, at the VPN server and at your service PC OpenVPN is been
used. See

Application areas
The Advanced People Sensor APS-90 and APS-180 can be used in buildings for counting
people in front of doors and passageways or in corridors and stairwells. Typical applica-
tion areas are retail shops, showrooms, train stations and airports.
Another use is the acquisition and evaluation of the movement of persons in a certain area
e.g in order to determine their length of stay.
Data is transferred via Ethernet or optional by WiFi.
