DYWIDAG Smart Guard
The DYWIDAG Smart Guard delivers rapid displacement event detection for rail and critical infrastructure. Detecting and verifying tilt events in under 5 seconds, it combines wireless sensors, integrated cameras, and DYWIDAG's Infrastructure Intelligence to provide instant situational awareness - helping engineers intervene early, minimise downtime, and reduce site exposure.

Reliable, real-time event detection
Smart Guard continuously monitors for displacement and stability issues, sending alerts the moment thresholds are breached. Unlike traditional monitoring systems that rely on periodic readings, it provides both live data and visual confirmation - helping rail operators and infrastructure owners detect potential failures before they escalate.
Key advantages:
Wireless tilt sensors for rail embankments and cuttings with configurable thresholds and sampling rates
Real-time displacement detection with alerts delivered by SMS, email, and Infrastructure Intelligence dashboards
Triggered camera imagery (day and night) to verify slope movement, track shifts, or other events on site
Ultra-low latency communication (<5 seconds) enabling rapid operational decisions and service protection
Rugged, field-proven design – IP68 tilt sensors and IP67 cameras built for harsh trackside and infrastructure environments
LoRa® wireless connectivity up to ~6 km with 4G backhaul for reliable remote monitoring
Low-maintenance operation with long-life batteries (~3.2 years estimated for sensors)
Network Rail approved
DYWIDAG Smart Guard is certified (PA05/07270) for use on the UK rail network as well as meeting standards ISO9001:2015, ISO14001:2015, ISO27001:2022
Displacement event detection
Smart Guard detects slope movement, track shifts, and embankment failures with <5 second latency, providing real-time visibility and early warning for rail and infrastructure.
Fast deployment
Pole-mounted sensors, wireless connectivity, and solar or mains gateways enable rapid installation with minimal works, ideal for rail corridors, tunnels, and bridges.
Built for scale
Smart Guard scales from a single embankment to full rail corridors. Multiple assets connect via one gateway, with all data centralised in DYWIDAG's Infrastructure Intelligence platform.
Connected monitoring for rail and infrastructure
Smart Guard integrates directly with DYWIDAG’s Infrastructure Intelligence platform, giving operators the confidence to act fast when displacement events occur. By uniting tilt sensor data with real-time camera verification, it delivers a single system to manage rail embankments, cuttings, and bridges. Raw measurements are transformed into clear, actionable insights - resulting in safer networks, reduced downtime, and fewer site interventions.
Platform capabilities include:
Real-time visualisation of displacement events with camera confirmation
Before/after comparison tools: overlay, side-by-side, and timeline animation
Custom dashboards with user roles and automated reporting for rail operators and asset owners
Multi-channel alerts (SMS, email, dashboard) with map-based asset views
Remote camera triggering for on-demand site snapshots

Supporting critical infrastructure
Manufactured and operated under ISO 9001:2015, ISO 14001:2015, and ISO 27001:2022 standards, Smart Guard ensures the highest levels of quality and information security. Purpose-built for early detection of ground movement and displacement events, it supports safer, more reliable rail infrastructure.
As the demand for accurate, real-time monitoring data grows, Smart Guard helps prevent incidents, protect assets, and strengthen passenger and workforce safety across the rail network. This advanced infrastructure monitoring system provides engineers and Permanent Way teams with continuous tilt and displacement data, verified by real-time camera imagery. Designed for rail embankments, cuttings, and bridges, Smart Guard delivers instant alerts when movement occurs - reducing response times, preventing costly disruptions, and enhancing trackside safety by keeping boots off ballast.
