The deployment diagram of the hybrid cloud version of Athena’s Walk Through Metal Detector / Weapons Detection System is displayed in the following network topology scheme below with XProtect from Milestone.

For the hybrid cloud version, you will only need to deploy WTMD/WDS systems at all of your building's entryways which people will be entering, while Athena takes care of the rest.

Each WTMD/WDS deployment is made up of one or multi WDS systems, 1 Athena's Control Center and 1 XProtect system. Athena Control Center can currently handle up to 5000 entryways per customer. The backend, updates, and monitoring services are handled by Athena. You will need port 443 outbound opened up from each WTMD/WDS iPad to the Athena Control Center.  Port number 9090 will be needed inbound to your XProtect server location from wds.Athena-security.com, please create a ticket to provide us the DNS name and IP Address of your XProtect server. 

IP addresses to lock down your firewall’s outbound ports can be provided by creating a support ticket, as this information is specific to your deployment.
