The Concurrency option lets you install and share one or more licenses on an unlimited number of computers (without a dongle!). This is a low-cost alternative to buying a separate license for each computer.

The number of concurrent (simultaneous) users is limited by the number of licenses purchased. If you buy one license, then only one computer at-a-time can operate Sentinel Visualizer (even though the software can be installed on many computers). Two licenses allow two concurrent (simultaneous) users, etc.

There are two requirements for Concurrency:

• While operating SentVi, the computer must have a constant, live connection to the Internet.
• An annual support contract must be maintained.

If your annual support subscription lapses, Concurrency is terminated. You can contact us to convert the license to a perpetual license that is installed on one computer.

Note 1: During the SentVi installation, we generate an anonymous identifier for each unique installation. When concurrency is enabled, we contacts our concurrency server periodically, passing this anonymous encrypted identifier. No machine identifiable information is exchanged between the SentVi client and our concurrency server. SentVi never sees or touches user data … we check only that the license is valid and that the number of current users does not exceed the number of licenses.

Note 2: If you need to operate SentVi on a portable computer “in the field,” then that portable computer must have an Internet connection to use a Concurrent license. If the computer does not have a constant Internet connection, it will need an individual SentVi license (without Concurrency). You can purchase concurrent and non-concurrent licenses in any combination/quantity.

To share a database between two or more users for multi-user collaboration (regardless of whether or not you have Concurrency), you must own the Multi-user or Enterprise. Those editions allow you to create a Microsoft SQL Server database on your network server or the cloud, rather than on your computer’s local hard drive. Your SQL Server administrator can set the security settings to limit the users. SentVi respects those security settings.

You do not need a SentVi license for the database server but you do need the appropriate Microsoft SQL licenses for your server and computers. Please contact us if you’d like a price-quote for Microsoft SQL Server.

If, for security reasons, you do not want certain users to have access to one or more databases, the Multi-user or Enterprise version also allows you to create databases on your local hard drive similar to the Single-user version.

Software as a Service (SAAS) is a subscription alternative to purchasing a perpetual license of the SentVi Premium Edition. Just pay for the time period you need.

You can install SentVi on multiple PCs, but can only run it on one PC at a time (per subscription).

SentVi SAAS is a desktop solution that requires an Internet connection.
