About Ktronics

Built around techs,
not salespeople.

Twenty-two years on, we still work the same way: design what you'll install, install what you've designed, maintain it for the life of the system. No sales team. No offshore help desk. When you call us, you get the people on this page.

Karl, Founder & MD

Founder

Started by a Kiwi who saw
a better way to do
commercial security.

Karl came over from New Zealand in the late nineties with a trade background and a clear idea of what good looked like: walk the site first, design to how the building actually runs, install properly, and stand behind the work for the life of the system.

He founded Ktronics in 2003 to build a business around that standard. Twenty-two years on, that's still how every job gets done. Karl now spends his time on direction and long-standing client relationships rather than day-to-day delivery.

The team behind him runs the design, install, monitoring, and maintenance work. Same standard. Same approach. Same answer when you call.

What we stand for

Four principles. Every job. No exceptions.

Custom-engineered, every site.

No catalogue packages. We walk your site, map your operations, and design to the way your people actually work.

One team, whole lifecycle.

Design, install, commission, monitor, maintain, upgrade. Same techs across all of it. No hand-offs to a stranger six months in.

Best-in-class, not flashiest.

We integrate Lenel, Genetec, Avigilon, Tecom, Axis. We pick the kit that fits the job, not the kit on the rep's commission ladder.

Decades, not deals.

Our oldest clients have been with us since 2003. We'd rather have you for twenty years than win a one-off install.

Track record

Twenty-two years of compliance-grade work.
Most of it you've never heard about.

Our clients are private by definition. We work on the buildings, sites, and infrastructure that need security precisely because being known as a target is the problem. So we don't name them. What we can tell you is the kind of work, the scale of it, and how long we've been doing it.
