On the south bank of the Yangtze River, a unique wetland ecosystem breeds a variety of fish and aquatic animals. Every autumn, this wetland attracts nearly 700,000 migratory birds (such as cranes and other rare bird species) for the winter. They live in harmony with lakes and fields, creating a beautiful picture of nature. However, due to the complex terrain of the wetland and the massive number of migratory birds, it has been challenging for local staff to manually take care of the reserve.

Utilizing the power of digital technology, Dahua provided an intelligent monitoring and management system featuring all-weather monitoring, early warning and analysis of ecological conditions in key wetland areas.

High-definition visible light PTZ cameras, thermal cameras and other equipment were deployed on field towers and utility poles to capture video images of the birds and the wetland in real time. These devices automatically monitor and record the species, quantity, distribution and trajectory of migratory birds in the wetland, as well as the conditions of the lake area, allowing the monitoring staff to remotely guard the wetland. It greatly helps them in performing their daily monitoring tasks and significantly improves their work efficiency. At the same time, the digital system with intelligent detection and early warning function can also aid rangers to better observe and manage the wetland, timely and effectively prevent wetland damage, and deter illegal intrusion, poaching and other external threats, creating a safe and peaceful migration environment for the birds.

Powered by a wind-solar hybrid power generation system, the images are transmitted to the corresponding migratory bird protection monitoring command center and provincial command center through wired or wireless (including 4G) transmission. While collecting real-time ecological data to maintain a healthy wetland environment, the system sorts out the data history and builds a comprehensive database of wetland ecosystem. Managers of the reserve can use these data to regularly review the wetland’s dynamic changes, distribution of migratory birds, and health assessment of the reserve, providing a decision-making reference for the wetland’s ecological conservation.

At present, this Dahua solution has helped protect more than 150 species of rare and exotic birds in the reserve, many of which are endangered species, as well as national first-class and second-class protected animals such as the white crane, oriental white stork, cygnet, gray crane and more.

With its mission of “Enabling a safer society and smarter living”, Dahua will continue to fulfill its social responsibility by exerting its utmost efforts in environmental protection, ecological balance, biodiversity, and carbon neutrality, utilizing its strength in digital intelligence and assisting the sustainable development of the global community.
