Ott HydroSight is a contactless video‑based monitoring solution for real‑time measurement of water level, surface velocity, and discharge in rivers and open channels. Installed safely beside the water, it uses advanced video analytics directly in the camera to deliver reliable, traceable flow data – even at challenging sites where traditional sensors are difficult or unsafe to deploy. Visual overlays and remote access enable continuous data validation, reduce site visits, and improve operational safety. With flexible camera options, low maintenance requirements, and global expert support, Ott HydroSight is ideal for flood monitoring and surface‑water applications.
