About Us

 The DSI Difference

After years of being sub-contractors to many leading security companies in Perth, we are happy and excited to step out on our own. With DSI, there is no middleman or sales consultants. You have direct access to the installers and after service people who know everything there is to know about your system. Every component, cable run and even the type of screw. This means that we provide you the best technical service at the optimum cost. Because you can contact us directly, we can guarantee fast response and troubleshooting. We take pride in our workmanship and aim to establish a long and trusting relationship with our valued customers. We will be there for you from the beginning to the end.
