THE CHALLENGEAn Offline ATM Is a Blind Spot
A modern ATM fleet is spread across branches, kiosks, and unmanned sites, and the cost of a failure is measured in lost transactions, vandalism, and physical attacks. Relying on a customer complaint or a guard to notice a problem means the bank finds out last. A monitoring unit inside each ATM senses tamper, vibration, door state, and shock, watches power and temperature, and reports uptime and security events to the backend in real time, so the operations centre sees a problem the moment it starts.
Built within the Telematics and GPS Tracking ecosystem, and frequently paired with Cash Van and Valuables Tracking.
WHAT'S INCLUDED
Sensing, Firmware, and Backend Integration
Tamper and Vibration Sensing
A high-rate MEMS accelerometer detects drilling, cutting, and impact signatures, with a tamper loop on the enclosure so an opened or breached cabinet raises an immediate event. Thresholds are tuned to separate an attack from a slammed door or a passing truck.
Door and Shock Monitoring
Safe and fascia doors are instrumented with reed and Hall sensors, with a dedicated shock channel for ram-raid and explosive attack profiles. Door open events outside authorised windows are flagged and timestamped for the audit trail.
Uptime and Health Monitoring
The unit watches mains power, UPS state, and reachability, so a power cut, a network drop, or a hung terminal is reported as downtime rather than discovered by a failed transaction. Uptime is tracked per ATM for SLA reporting.
Environmental Monitoring
Temperature and humidity inside the cabinet are logged, because overheating in an unmanned kiosk is a common cause of cash dispenser and PC core failure. Trends warn before a thermal fault takes the ATM offline.
Security Alerts and Escalation
Prioritised alerts for tamper, forced door, shock, and power loss are pushed over the cellular link, with local siren and strobe triggers where fitted. Escalation rules route critical events to the security desk and quieter ones to maintenance.
Backend Integration
Designed to integrate with the bank or operator monitoring backend and ATM management software over MQTT and REST, so events, uptime, and environment land in the systems your operations and security teams already watch.
WHAT IT CATCHES
The Events That Matter, Separated From Noise
An ATM monitor is only useful if it raises real incidents and stays quiet otherwise. Detection is tuned so security, operations, and maintenance each get the events that belong to them, with enough context to act.
Physical Attack
Drilling, cutting, ram-raid, and explosive shock signatures trigger an immediate high-priority alert to the security desk, with local siren and strobe where fitted and a timestamped record for investigation.
Operational Fault
Power loss, UPS depletion, network drop, and thermal warnings are routed to operations and maintenance so downtime is fixed fast and SLA impact is logged automatically.
Routine Access
Authorised cash replenishment and service door openings are recognised against schedules so they confirm rather than alarm, keeping the operator focused on genuine exceptions.
HOW IT WORKS
Sense, Decide, Report
Sense at the Edge
An STM32 reads the accelerometer, door and tamper loops, and power and temperature channels continuously. Sampling is fast enough to capture an attack signature, not just a steady-state reading.
Decide Locally
Firmware on a FreeRTOS base classifies events at the edge, so a real tamper fires instantly even before the cloud is involved, and false triggers from vibration or routine access are filtered out before they ever leave the unit.
Report Securely
Events stream to the backend over MQTT with TLS through a Quectel EC200 or BG95 modem, with NB-IoT or Cat-M1 for low-power kiosk sites. A store-and-forward buffer means a dropped link never loses an event.
STANDARDS AND ENGINEERING
Built for Banking-Grade Reliability
Secure Communications
Device to backend runs MQTT over TLS with per-device certificates, and firmware is signed with secure boot so the monitoring unit itself cannot be quietly tampered with or spoofed.
Resilient Power
The unit runs from the ATM supply with a backup so it keeps reporting through a mains cut, and it treats the power transition itself as a monitored event rather than a silent gap.
Field Serviceable
Enclosures and wiring are designed for branch and kiosk installation by field technicians, with diagnostics and remote firmware update over the air so the fleet stays current without site visits.
FAQ
Common Questions
How does the system tell a real attack from normal vibration?
A high-rate MEMS accelerometer is sampled fast enough to capture the signature of drilling, cutting, and impact, then classified at the edge against tuned thresholds. A slammed door, a passing truck, or routine vibration does not match an attack profile, so the unit confirms rather than alarms. The classification runs locally so a genuine tamper fires instantly.
Does it keep working during a power or network outage?
Yes. The unit runs from the ATM supply with a backup so it keeps sensing and reporting through a mains cut, and it logs the power loss itself as an event. If the cellular link drops, a store-and-forward buffer holds events and sends them the moment connectivity returns, so nothing is lost.
What kinds of events does it report?
It covers physical attack signatures such as drilling, cutting, ram-raid, and shock, forced or out-of-window door openings, power loss and UPS depletion, network drops, and thermal warnings. Authorised cash replenishment and service access are recognised against schedules so they confirm instead of alarming.
How does it connect to your existing monitoring backend?
Designed to integrate with your bank or operator monitoring backend and ATM management software over MQTT and REST, with per-device TLS. Events, uptime, and environmental data land in the systems your operations and security teams already use, rather than forcing them into a separate console.
Can it use low-power connectivity for unmanned kiosks?
Yes. For kiosk and remote sites, NB-IoT and Cat-M1 are supported alongside standard LTE through Quectel EC200 or BG95 modems. That keeps recurring connectivity cost low while still delivering real-time security alerts and uptime reporting.
Is the monitoring unit itself secure against tampering?
Yes. Firmware uses secure boot and is signed, device communications run over TLS with per-device certificates, and the enclosure is on its own tamper loop. If someone tries to disable or spoof the monitor, that attempt is itself a reported event.
