Smart Asset Monitoring, Engineered for the Field
Sentinel Monitors from map16 offer a new standard in asset monitoring – blending rugged engineering with real-time analytics to give you full control over your network performance. Whether you’re overseeing urban catchments or rural highway infrastructure, Sentinel provides live insight where you need it most.
Designed and built in the UK, Sentinel monitoring solutions support proactive, data-driven asset management that helps reduce risk, cut reactive maintenance, and deliver long-term cost savings.
Why Sentinel?
Your networks are under increasing pressure from urban growth, ageing infrastructure, and climate change. map16 built the Sentinel monitoring range to meet these challenges head-on – with a series of monitors that are:
Tough enough for harsh underground environments
Smart enough to detect risk before failure
Simple enough to deploy at scale
Sentinel enables engineers, asset managers, and contractors to take a preventative, strategic approach to asset maintenance – reducing blockages, protecting budgets, and extending asset life.
Core Capabilities
Continuous Monitoring with Zero Downtime
The Sentinel Core+ dual-battery configuration keeps devices active for up to 7 years – even through long service intervals. No power gaps. No missed data.
Built to Withstand the Extremes
Encased in an IP68 polycarbonate shell and certified for ATEX Zone 2, Sentinel monitors are engineered for the most demanding environments.
Strong Signal, Even Underground
Our custom LTE CAT1Bis antenna improves signal strength by up to 30%, enabling reliable, real-time data transmission from even the hardest-to-reach chambers.
Fast, Accurate Installation
The quick-mount bracket and built-in alignment tool reduce setup time and errors. Paired with the map16 mobile app, installers get instant confirmation of correct placement.
Smart by Design
Sentinel Monitors don’t just detect change – they understand it. From blockage indicators to flow anomalies, the system turns raw data into usable insight.
Seamless Data Flow
Adjust sampling and send frequency via web interface - remotely and in real time. Choose from preset intervals or tailor performance based on network priorities.
Versatile Range & Accuracy
Monitor depths from 0m to 20m, with precision calibrated for wastewater systems of all sizes - urban or rural, combined or separate networks.
Fully Integrated with map16
Our monitors connect directly to the map16 platform, allowing data from your monitors to sit alongside gully assets, drainage systems, and highway safety infrastructure
One system. One dashboard. One source of truth.
Data Integrity & Compliance
Data is end-to-end encrypted, with secure storage, transit protection, and full alignment with UK infrastructure data standards. Your insights are safe, and your systems futureproofed.
Visual Validation with Sentinel VisionPro
Our enhanced unit, VisionPro, includes a high-grade infrared prime lens for chamber imaging - supporting remote asset condition reviews and validating performance data.
