The Zenitel difference

Superior Audio Quality

Your ability to hear, be heard and be understood in emergency situations is essential.

Zenitel’s Intelligent Communication systems are used in schools and universities globally, due to their unrivaled sound and audio quality.

Integrated Communication

Efficient communication requires a single integrated communication platform.

We support open protocols such as SIP that make it simple and straightforward to do all your communication from one central console.

Integrated Security

Reliable communication between different systems is important. We share information through common protocols or dedicated drivers with other parts of the security system like Access Control and Video Cameras to enable automated processes.

This makes it easier for your security team to work much more efficiently when faced with critical events.
