About Us
Our Profile

Established 1971 when electronic security systems were a rarity in Perth, husband and wife team Bill & Patricia Robinson worked hard combining the simple electronics of the day with considerable craft and ingenuity. The result was a reliable and successful family business installing and servicing security systems, with heavy emphasis on the needs of the client.


After purchasing a building in Guildford, Bill Robinson designed and set-up SESCO's own 24-hour monitoring station in 1980. Several extensions and system upgrades later, SESCO still operates from the same premises. SESCO combines a rare blend of technological relevance with sincere and competent service. It is what sets SESCO apart from many others in the security industry

Security Systems

As a university student, son Gary Robinson assisted at SESCO installing systems and working in the monitoring station, building 'hands-on' experience as well as a deep understanding of company philosophy. Following graduation and several years in policy development and research, Gary joined SESCO in 1990 as General Manager.


Today, SESCO has a reputation envied by many in the industry.

The SESCO leadership team is committed to operating efficiently and ethically in a sophisticated market. SESCO is committed to raising standards within the security industry and is actively involved with the national security industry association, ASIAL.
