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.

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.

The SESCO focus is on the client which is why a majority of new business is through referrals from existing, satisfied clients.
