OUR STORY
Significant flooding events had occurred in our city, not because stormwater assets didn’t exist, but because there was no information about how the network was actually performing. Blocked catch pits and underperforming assets went unnoticed until heavy rainfall exposed the issue — by which point the consequences were already visible.
Subtle changes during small rainfall events would have revealed blocked or poorly maintained assets, but at the time there was no practical way to monitor stormwater infrastructure at scale. Accurate monitoring was expensive, slow to deploy, and not suited to widespread use across thousands of low-value but operationally critical assets.
We created HiLo to change that.
We're on a mission to enable better operational decisions by making reliable level data available where it was previously impractical or impossible.
As monitoring became cheaper and more widespread, a new problem emerged: in challenging environments, data quality often wasn’t good enough to trust. False alarms, signal clutter, condensation, and environmental interference limited the usefulness of many “at-scale” monitoring solutions.
HiLo’s mission is to close that gap.
Through the use of industrial-grade radar and intelligent detection algorithms, we focus on delivering trustworthy data in the most challenging environments — underground, remote, exposed, or hazardous sites — where accurate monitoring delivers the greatest operational return.
By reducing false alarms, simplifying installation, and making difficult sites viable to monitor, HiLo enables organisations to move from reactive response to proactive, data-driven asset management.
HiLo designs and manufactures low-power radar level monitoring equipment with integrated telemetry, purpose-built for deployment in harsh and hard-to-access environments. Selected products are IECEx certified for explosive zones and feature IP68 environmental protection, enabling long-term operation in underground, exposed, and hazardous locations.
Our mobile applications support fast, intuitive installation, while our cloud-based platform makes it easy to manage devices, data, and alerts at scale. HiLo integrates with modern data platforms via APIs and also offers self-hosted software options for enterprise and utility customers operating private networks, including SCADA environments.
HiLo is based in Dunedin, New Zealand, with our engineering, product development, and customer support handled in-house. This allows us to stay close to the environments our technology is used in and to support customers directly as their needs evolve. HiLo is led by founding directors Mark Butler and Jesse Teat, who continue to guide the development of our products and work closely with customers across New Zealand and Australia.
