Building the UK's IoT data network
Expanding rapidly across the UK, the ZARC Network grows stronger with every node deployed — each one extends coverage, and where coverage overlaps the network gets more resilient for everyone on it. Wherever a tag's data travels across the network, it only ever returns to the client who owns the asset.

ZARC Network™ stands for Zero-Trust Architecture Radio Communications. It is a UK low-power IoT data network built from authorised coverage cells across customer deployments.
Every authorised gateway strengthens the coverage fabric around it. More gateways create more redundancy, stronger reception, cleaner event data and a more useful network for customers running approved devices, sensors or monitoring applications.
Over a million data points reported every day
Authorised coverage cells across critical locations
433 and 868 MHz low-power radio support
Encrypted, tenant-isolated data routing
Your sensor.
Any application.
Bring the approved device, use case or field constraint. We can shape the device form factor, route authorised payloads through ZARC and deliver them into a bespoke dashboard, API or alert workflow.
Fire-suppression system monitoring
Water and gas metering
Environmental telemetry
Door, access and security events
Tank, level and leak detection
Power and equipment monitoring
Asset condition monitoring
In-transit telemetry (temperature, motion, tamper)
Critical estate visibility
From field sensor to owned operational data.
Authorised payloads can be shaped around the application, routed through ZARC coverage and delivered into dashboards, APIs or alert workflows.
01
A ZARC device is not dependent on a single receiving gateway within an authorised deployment. Where permitted transmissions are received by more than one authorised coverage cell, the platform reconciles duplicates and retains the cleanest event record.
02
When more than one authorised coverage cell receives the same permitted transmission, the platform reconciles duplicates and preserves the clean event record. Coverage overlap is used for resilience, certainty and data quality.
03
Every authorised payload is authenticated, encrypted and routed only to the authorised owner or platform tenant. Data is not shared across customers. Gateway reception does not expose one customer's telemetry to another.
04
Events can feed dashboards, APIs, alerts, notifications and operational workflows. Reporting can be tuned for instant alarms, regular telemetry, low-frequency metering or long-life monitoring profiles.
ZARC supports both 433 MHz and 868 MHz radio strategies. 433 MHz gives deep penetration and long-range behaviour for difficult environments such as basements, utility spaces, dense buildings and remote estates. 868 MHz supports compatibility where customers already operate suitable devices.
The network is designed for low-power reporting. A monitored device may report frequently where operational visibility is required. A meter or buried sensor may report rarely to preserve battery life. The reporting interval is configured around the client requirement, the payload and the application risk.
Water ingress, door and access events, tamper and movement-detection events, power loss and security events can trigger immediate alerting where fast intervention matters. Smoke and heat are monitored to complement existing fire and life-safety systems — never as a replacement for them.
Sensors can report every 30 seconds, every few minutes, hourly, daily or on another agreed schedule where the use case values battery life and trend data over constant transmission.
Battery life depends on the device, payload, interval and RF environment. Many real-time tag profiles are designed around multi-year operation, while low-frequency applications such as underground water meter reading can support much longer field life.
A ZARC device reports its readings outward — sensor to coverage to platform to your dashboard. No handshake to wait on, no dependency on a single receiver, minimal power burned. The device reports, the network carries it, the owner gets the data.
The case for ZARC
Most monitoring networks were designed for something else. Cellular modules assume every device justifies a SIM, a data plan and the power budget of a phone. Wi-Fi assumes the asset lives inside a managed network, and that the IT department wants a hundred new devices on it. Both are reasonable assumptions for high-value, mains-powered equipment — and wrong for almost everything else on a working site.
ZARC was built for the everything else: the long tail of unattended assets whose state quietly matters — the plant-room gauge, the cold store, the cabinet on a verge, the meter under a cover plate. These assets share a profile: no spare mains, no network drop, no one watching, and a per-asset value that cannot carry connectivity designed for smartphones. A ZARC device strips the problem to its core — sense one thing, report it the moment it changes — and that restraint is what buys multi-year battery life, low installed cost, and radio that keeps reporting from enclosed, signal-hostile spaces.
It also means deployment looks different. There is no integration project and nothing added to the site's IT estate; a device is fixed to the asset and reports into ZARC coverage from day one. The network does the rest — and because every new authorised gateway strengthens the coverage fabric around it, the network a customer joins this year is stronger than the one the last customer joined.
What runs on ZARC
These are the monitoring disciplines running on ZARC today — each one retrofit, battery-powered, and reporting in real time.
ZARC Network FAQs
The ZARC Network is a UK low-power IoT data network operated by IoT Technologies. ZARC stands for Zero-Trust Architecture Radio Communications. Battery-powered sensors and tags report readings and state changes one way, over 433 and 868 MHz low-power radio, into authorised coverage cells; the platform turns those reports into live dashboards, instant email and SMS alerts, and a timestamped record for every asset.
No. ZARC devices contain no SIM and use no Wi-Fi, and nothing is added to the site's IT estate. Each device reports over low-power radio into ZARC coverage, so monitoring can be added to plant rooms, basements, cabinets and remote sites without mains power at the asset, site connectivity, or an integration project.
No, and that is deliberate. ZARC is a one-way telemetry network: devices report outward, and the network carries no commands back into a site. A monitoring device that cannot receive instructions cannot be remotely commandeered, which keeps the monitoring layer off the list of things a security team has to defend. ZARC is a monitoring and alerting layer, not a control system.
No. Routing is zero-trust and tenant-isolated end to end: every payload is authenticated, encrypted, deduplicated and delivered only to its authorised owner. Reception by the network never exposes one customer's telemetry to another, and the network is UK-operated.
Coverage is overlapping by design. Where more than one authorised coverage cell receives the same transmission, the platform reconciles the duplicates and keeps the cleanest event record — so a busy or blocked route doesn't cost a reading, and every gateway added strengthens the fabric for everyone.
It depends on the device and its reporting profile. Real-time alerting profiles are designed around multi-year operation, while low-frequency applications such as underground water meter reading support considerably longer field life. Battery life is engineered against reporting cadence at deployment rather than assumed.
Anything with a state worth knowing: pressure, temperature, humidity, leak and water ingress, liquid and tank level, door and access events, mains power, equipment running or stopped, and meter readings. Real-time alarms, scheduled telemetry and long-life sensing profiles run on the same network.
ZARC coverage cells receive only authorised transmissions within permitted deployments, and the data path is tenant-isolated end to end. Every payload is authenticated, encrypted, deduplicated and routed solely to its authorised owner. Reception by the network never exposes one customer's telemetry to another. You keep control of your data, your alerts and your operating rules — on a UK-operated network.
