About Guardline Security

When we started Guardline Security, most wireless outdoor sensor companies were selling products that were old and unreliable. The industry was satisfied with products that were just good enough. Not us. We saw the need for excellence in both product and customer service, and we created a company that is unrivaled in the marketplace. When it comes to protecting your property, home, and family Guardline knows that “good enough” is something no one should settle for.
