River Sentry product offering
Product offeringCore offering
River Sentry designs, manufactures, and installs autonomous flash flood detection and warning tower systems (RS-1A, RS-1B, RS-EW, RS-LWC, RS-TC, RS-FC) that combine dual submersible water sensors, 130dB+ sirens with voice commands, and directional lighting to alert sleeping occupants during flash floods. The systems operate without power grid or internet connectivity, are backed by a companion mobile app on RS-1B models, and are complemented by annual service plans and maintenance services.
Product overview
River Sentry offers a unified portfolio of autonomous flash flood detection and warning systems centered around the RS-1A and RS-1B tower products, supplemented by specialized variants (RS-EW Early Warning, RS-LWC Low Water Crossing, RS-TC Town Center Alert) and a residential Flood Cube. The core RS-1A/R S-1B towers serve as all-in-one detection and alarm systems installed between water threats and sleeping quarters, featuring water sensors, sirens, voice commands, and lights. The RS-1B adds wireless connectivity for multi-tower coordination. Services include annual maintenance plans, ad-hoc maintenance, re-certification, and removal/upgrade services. A companion mobile app provides monitoring and drill capabilities for RS-1B and Flood Cube users.

River Sentry competitors and assessment
Company assessmentBroad incumbents
- Xylem: Xylem is a global water technology company offering smart metering, network monitoring, and flood/wastewater management solutions. Overlaps with River Sentry in water monitoring and flood management, but as a broad portfolio incumbent rather than a flood-warning specialist.
- Motorola Solutions: Motorola Solutions provides mass-notification and emergency-warning systems (sirens, public-address) used by municipalities and governments. Comparable to River Sentry in outdoor siren-based emergency alerting for public safety, though not specifically flood-detection integrated.
- Honeywell Building Technologies: Honeywell's Building Technologies division provides integrated life-safety, alarm, and emergency notification systems for commercial and public-sector buildings. Comparable to River Sentry in emergency-alert and warning-system delivery, though focused on indoor building systems.
Direct peers
- Campbell Scientific: Campbell Scientific manufactures rugged environmental monitoring instrumentation including flood and water-level sensors. Comparable to River Sentry in producing industrial-grade, autonomous, outdoor measurement systems with telemetry, though typically sold as components rather than turnkey warning systems.
- StormSensor: StormSensor provides real-time flood and stormwater monitoring sensors for urban infrastructure. Comparable to River Sentry in deploying autonomous water-level sensors with continuous data output, though focused on municipal roadways rather than life-safety alarm sirens.
- Sutron Corporation: Sutron manufactures hydrometeorological monitoring and telemetry systems for water resources agencies. Comparable to River Sentry as an instrumentation provider for real-time flood/stream monitoring, with overlapping customer segments in government and utilities.
- FloodMapp: FloodMapp delivers real-time flood forecasting and early-warning intelligence for communities and infrastructure operators. Comparable to River Sentry in mission and customer base (property/camp operators and governments seeking flash flood warning), though delivered as a SaaS analytics platform rather than hardware.
- OneRain: OneRain provides real-time environmental and water monitoring solutions for stormwater, flood, and weather applications. Comparable to River Sentry in deploying autonomous flood/rainfall sensing infrastructure with continuous monitoring capability.
Emerging players
- Roost: Roost provides smart-home sensors for water leak detection and environmental monitoring with mobile alerting. Comparable to River Sentry in flood/water-detection sensor technology and app-driven alerting, though focused on indoor home use cases.
- Whisker Labs: Whisker Labs makes wireless sensors for environmental hazards including water leaks and flood detection in residential and commercial properties. Comparable to River Sentry in deploying autonomous flood/water-detection sensors with consumer-friendly installation, though typically property-level rather than outdoor warning systems.
