Sentinel Core Monitors
The Sentinel Core monitor is map16’s specialist monitoring solution for street-level assets – designed to keep highways functioning efficiently and reduce risk across your network.
With built-in intelligence and real-time level monitoring, Sentinel Core gives local authorities and contractors the data they need to predict issues, optimise cleansing, and take a proactive approach to highway management.
What Makes Sentinel Core Different?
While traditional monitoring systems focus on below-ground infrastructure, Sentinel Core targets surface-level assets – the first line of defence against flooding on highways and public roads. From blocked grates to rising water levels, our Core monitor provides the insights needed to manage and maintain these critical assets with confidence.
Monitor What Matters.
In Real Time.
Sentinel Core monitors continuously track key conditions across your network:
• Water levels (% full)
• Whether the gully lid is open or closed
• If the grate is covered or obstructed
• Full network visibility via map-based interface
• Real-time alerts for pre-flooding thresholds
This data feeds directly into your map16 platform, helping teams automate response plans and maintain compliance.
Addressing the Core Challenges
Adapting to Climate Change – One monitor at a Time
As rainfall events become more frequent and intense, surface flooding is no longer a seasonal issue – it’s a constant risk. Sentinel Core arms your team with predictive insight to:
-
Understand how gullies behave under weather stress
-
Plan cleanses ahead of peak conditions
-
Reduce emergency callouts and costly damage
-
Safeguard communities and infrastructure
Designed for Field Simplicity, Built for Highway Durability
4G Monitor Specs:
• Custom-engineered for maximum battery life & signal strength
• 5+ years battery life
• No removal required during gully cleanses
• Detects lid openings and grate coverage
• Fully ruggedised for highway environments
• No maintenance required
Predictive Analytics That Power Action
Use advanced analytics to simulate:
• Best-case and worst-case flooding scenarios
• How specific gullies will respond to incoming weather
• Areas most in need of attention before an event occurs
With this intelligence, your team can shift from reactive to truly proactive maintenance planning.
Visualise Your Network in Real Time
With map16's map-based dashboard:
• View monitor locations and conditions across your network
• Filter by asset type, fill percentage, or priority level
• Access a live timeline of each asset status
Whether you’re managing a rural highway or an urban city grid, Sentinel Core keeps your drainage data at your fingertips.
Future-Focused Drainage Innovation
At map16, we’re committed to helping local authorities and contractors respond to the evolving challenges of wastewater and stormwater management. Sentinel Core is our advancement in providing accessible, scalable, and intelligent tools to those responsible for public safety and resilience.
