Remote monitoring systems for equipment and sites
IoT Technologies designs and builds remote monitoring systems for equipment and sites that would otherwise go unmonitored. Battery-powered wireless sensors fit to existing assets and turn local alarms, readings and events into live dashboards, instant alerts and records you can trust.
Solutions
Engineered for certainty.
Built for scale.
From a single cabinet to an estate of remote sites, we monitor the conditions that matter: pressure, temperature, leaks, power, fire and more. We turn site signals into live alerts, real-time data and bespoke dashboards built around the assets you already run.
A few of the systems we design and deploy.

Cabinet and site monitoring alerts
Cabinet & Site Monitoring
Real-time visibility for telecoms cabins, cabinets and remote sites, covering temperature, power, door and movement, with instant alarms.

Real-time cold storage monitoring
Cold Storage Monitoring
Continuous temperature monitoring for coldrooms, fridges and freezers. Alarms the moment a unit drifts out of range, with records to prove it.

Real-time perimeter security systems
Perimeter Security Alarms
Real-time perimeter monitoring for compounds and secure sites. Instant alarms the moment movement, intrusion or tampering is flagged.

Air quality compliance solutions
Air & Extraction Monitoring
Real-time air quality and extract monitoring across your sites. Catch a failing filter or rising emissions before a complaint does.

Real-time pressure monitoring and alerts
Pressure Monitoring & Alarms
Real-time pressure alarms across every asset, line and cylinder in your estate, the instant pressure rises or drops, on one dashboard.

Leak detection and meter reading
Metering & Leak Detection
Automated meter reading and leak alarms from one wireless sensor. Usage recorded, and water ingress flagged the moment it starts.
Products
The ZARC family of tags
A family of monitoring and alerting tags that digitise the state of equipment you already own — pressure, level, temperature, current, water, contacts, alarms. Each one attaches to kit you already have, reports over the ZARC network, and alerts you when it matters. Designed, built and manufactured to order in the UK.

Field proof
Engineered for the field. Trusted in production.
From raw signal to operational decision.
Sensors, gateways, clean records and operational dashboards deployed on real sites.
Telemetry at scale
Telemetry at scale
Field operations that need live data, not manual reports.
Thousands of sensors reporting through distributed gateways, turning field events into usable operational data in real time.
Security and response
Security and response
Assets and sites that need to be watched, not just checked.
Security events become useful only when they are seen quickly, recorded cleanly and routed to the right response path.
Estate visibility
Estate visibility
Visibility that needs evidence, not assumptions.
Remote sites, buildings and estate assets need continuous visibility when manual inspection is slow, expensive or incomplete.
Have a field deployment, compliance problem or remote asset estate that needs better visibility?
Discuss a deploymentHow it works
From site survey to live alerts
A clear path from first site survey to live monitoring and alerts. Retrofit monitoring you deploy on the kit you already run, reviewable at every stage before work proceeds.
No rip-and-replace. No uncontrolled scope. Each stage produces a clear output before the next begins.
Survey
We assess the site, the assets you already run and the conditions you need to watch.
Specify
We agree the sensors, gateways, alerts and dashboards that fit the site, and how the monitoring retrofits to your existing kit.
Deploy
Low-power devices are retrofitted to your assets and sites and brought online — no rip-and-replace, no bespoke build.
Monitor
Live data flows into alerts and dashboards, so the conditions that matter reach the right people the moment they change.
Support
We keep the monitoring running and supported as part of day-to-day operations, refining alerts and cover as needs change.

We build the whole stack.
IoT Technologies is a focused, senior team of IoT engineers, not a sales organisation. Between us we have spent years on some of the most demanding deployments in the field, and owning every layer is why our monitoring is affordable, low-power and retrofits to the kit you already run.
That means hardware, firmware, connectivity, back end and front end, all ours. No low-code shortcuts, no off-the-shelf platform doing the heavy lifting. That is how our monitoring stays affordable and low-power, retrofits to the kit already on your site, and is something we stand behind once it is there.
Front end & dashboards
The interface your team actually uses, built to the same standard as everything beneath it.
Data platform & back end
Ingest, storage and the logic that turns raw telemetry into something your operation can act on.
Connectivity & networking
Gateways, links and protocols chosen for real-world coverage, power and field conditions.
Firmware
Device-level code written for the exact sensors and constraints of each deployment.
Hardware & manufacture
Boards and enclosures specified and built for the job, not adapted from a kit.

Channel partner programme
If you supply equipment to your own customers, we can put it on a dashboard that carries your brand. You sell the monitoring as yours; we build and run the hardware, firmware and platform behind it.
Your brand, your client relationship — the dashboard is bespokely yours.
Retrofit battery-powered tags fit the equipment you already install and service.
All the heavy lifting is ours: hardware, firmware, connectivity and platform.
Make your site signals visible, usable and evidenced.
Tell us about the sites, assets and conditions you need to monitor. We will help scope a practical pilot for reliable telemetry, real-time alerts and evidence-ready reporting.
