Alert Security

Alert Security, established in 1985, is a Canadian-owned and operated security solutions provider serving South Western Ontario. Our team of experienced professionals specializes in customized security and safety systems, including burglary alarms, video surveillance, door access control, intercom systems, and GPS vehicle tracking. We pride ourselves on delivering personalized service without subcontracting installations, ensuring direct accountability for every system we install and maintain. Our philosophy centers on treating clients with respect and integrity, fostering long-term relationships through reliable 24/7 monitoring and responsive support. With decades of industry expertise, we provide cutting-edge technology tailored to individual client needs, from single-camera setups to complex multi-system integrations.

Our unique customer portal allows clients to manage emergency contacts and notification preferences independently, reflecting our commitment to empowering users. Unlike many alarm dealers, we retain full responsibility for ongoing service, minimizing issues through meticulous initial installations. Our success, driven by word-of-mouth referrals, underscores our dedication to client satisfaction and peace of mind. We serve both residential and commercial clients, combining technical proficiency with personalized care to deliver comprehensive security solutions. Our Thornhill-based operations maintain rigorous standards, ensuring every project receives the attention it deserves as if protecting our own properties.
