Our Service

At McCallister Security Inc we believe security isn’t just about alarms and cameras. It’s about connection, confidence, and peace of mind. Based in Niagara Falls, Ontario, we’re a locally owned and operated company dedicated to helping homes and businesses stay connected, protected, and prepared.

From smart alarm systems and CCTV cameras to networking, structured cabling, access control, and audio/video, we build systems designed around how you live and work. Every project we take on big or small is treated with the same attention to detail, reliability, and craftsmanship that we’d expect in our own homes.

Our team combines technical expertise with a personal touch, bringing years of experience in low-voltage systems, security installation, and smart technology integration. We partner with trusted brands to deliver modern, dependable solutions that are built to last.

Our Mission

To protect what matters most with systems built on trust, technology, and true craftsmanship. We’re here to make security smarter, not harder. That means designing solutions that fit your space, your lifestyle, and your budget whether it’s a family home, a small business, or a commercial property. We don’t just install equipment, we build reliable, easy-to-use systems that give you peace of mind long after we leave.

Our Purpose

Our purpose is to raise the standard for local security and technology services in Niagara by combining hands-on expertise with honest advice, clear communication, and a relentless commitment to quality. Every wire, device, and connection we install is backed by our 1 year Peace of Mind Warranty and the promise to treat every project like it’s our own.
