Sontec Integrated Systems is a Western Australian based low-voltage (LV) services contractor with a 40+ year history of undertaking projects in Western Australia.

The origins of Sontec date back to 1978 in West Leederville, where the focus was predominately on audio, sound and intercom work.

The growth of Closed-Circuit TV technology coupled with substantial improvements within electronic Access Control systems created the new role of systems integrator.  

Sontec transitioned to the design and installation of enterprise LV solutions, engineered so that disparate technologies would operate within the one seamless security solution.

We specialise in medium-to-large commercial (only) systems. We also offer consultation and engineering services to create a bespoke cost-effective and client-centric solution. We remain independent and privately owned.

Sontec undertakes the complete installation and provides ongoing 24/7 maintenance and repair support within the entire state of Western Australia.
