Autonomous flood detection and warning—designed to operate when conventional infrastructure may not.
The RS-1A and RS-1B are autonomous flood warning towers designed to detect rapidly rising water and provide immediate local notification to people in the area.
Built around three principles—Effectiveness, Simplicity and Resiliency—River Sentry systems are designed for locations where lives may be at risk from flash flooding, including campgrounds, RV parks, vacation properties, lodges and other remote sites.
River Sentry Towers are installed between potential flood waters and occupied areas. When dangerous water levels are detected, the system can:
The system is designed to provide a local warning at the property where the threat exists, reducing dependence on occupants receiving an alert through a phone, internet connection or centralized warning system.
River Sentry Towers are engineered to provide protection without dominating the landscape. The tower incorporates its sensing, communications and warning components within a compact enclosure, with no large external satellite dish or prominent antenna.
At approximately 8 feet tall and 8 inches square, the tower has a small physical footprint while providing elevated placement for flood detection and local warning.
The RS-1A provides autonomous local flood detection and warning for individual installations.
It is designed for straightforward deployment and operation with minimal ongoing interaction, making it suitable for properties where reliable local warning is critical.
The RS-1B adds integrated wireless communications, allowing individual towers to operate as part of a coordinated River Sentry network.
This enables:
One tower can protect a location. A network of River Sentry Towers can protect an entire site.
