Redundancy

“Backups are […] insurance. Not having a backup is a frightening prospect." (SmartComputing.com)

It’s a basic rule of life in a largely unpredictable world that even the best technology is subject to the occasional malfunction. As a result, backup structures are an essential part of any IT-based system. Doing so makes good business sense. But with security-critical applications such as Intercom, the stakes are much higher, as human lives frequently depend on it. In these cases, the usual backup strategies won’t do.

Because every single word counts in critical situations, Commend Intercom solutions are designed to make sure the message (or control signal) gets through under any circumstances.

This is why Security Intercom solutions come packed with a range of extra redundancy features to ensure full, all-year, round-the-clock fail safety:

• Redundant connections mean that in case the connection is down, connections will automatically be re-routed through independent standby lines (often of a different transmission technology) to sustain connectivity even in case of a network failure.
• Redundant, independent power supply means that the entire system can be powered independently in case of a blackout or emergency to sustain all essential communication and control functions.
• Redundancy ensures compliance with high availability standards.
