3M System Upgrade and Sentry System Upgrade

Make Old 3M and Sentry Library Systems New Again!

The Sentry RT Controller is an upgrade for Sentry WAM-2 & MM systems, as well as 3M 3500 & 3900 to make old systems new again. By simply replacing old electronics with our RT Controller, your security gates are alive again with better tag detection and a remote tuning feature to perform system diagnostics, and adjustments via the internet.

The Sentry RT Controller has an optional built-in patron counter with LibraryAssist™ software that enables librarians to access detailed patron count reports using a local area network connection.

Electronic outputs add further security options, such as an alarm signal to trigger a video recorder.
