Dahua helps protect natural resources in China's river areas

In the Tuo River, thermal cameras have been used. Dahua to conserve the environment, Empowering water resources with digital intelligence and protecting aquatic biodiversity.

The Tuo River has 655 kilometers long and is one of the main tributaries of the Yangtze River. Surrounded by rich ecological landscapes and green mountains, is home to a variety of fish species, Like the catfish of the south, tilapia, long-beaked catfish and barbel fish. The ten-year fishing ban on the entire Yangtze River that began in 2020 paved the way for their conservation and protection .

However, Illegal fishing activities still occur within its waters from time to time, which are mostly undetectable and hidden in plain sight. To address this issue, the Dahua surveillance solution was implemented to monitor the 24 hours of the day, The 7 days of the week against these activities, Protecting natural aquatic resources in the river.

The Tuo River extends to 94 kilometers within the territory of Fushun County. It is accompanied by numerous tributaries, forming a branched network of the water system. It is winding and the shore is covered with bushes, what has become a natural barrier to various fishing activities. However, This natural protection also makes it difficult to regularly patrol the area..

With the solution of Video monitoring of Dahua, The patrolling process is simplified to make it more efficient and effective. With the aim of covering the entire river, several image collection points have been installed in water areas and key regions of the Tuo River.

System automatically completes daily inspections, while the management staff completes their patrols from the command center. Perform a one-on-one inspection of the preset points every half hour, around 30 seconds for each point. During this period, Violations are automatically identified and evaluated. When abnormal situations are found, Management staff receives an alarm on the platform, urging them to review footage in real time to detect any illegal activity on the river and respond in time if necessary.

When conducting on-site patrols, The most difficult task is the night ones. Illegal fishing activities also frequently occur during dark nights.. Low-light conditions along the banks of the river make it difficult to monitor the area. In addition, The location of offenders is somewhat hidden, which makes it difficult to detect.

The Thermal Camera Dahua can overcome visual limitations. Using thermal imaging technology, Intruders or illegal fishing boats in dark environments can be detected and stopped quickly. Even if offenders try to escape, The system can process and analyze your whereabouts in time.

“During video patrols, Thermal images make them appear as bright as day. Unauthorized persons are particularly visible at the scene. Real-time location, The direction of the boat and surrounding conditions can be obtained through video playback, which is something that cannot be done only with the naked eye", explains local management staff.

Today, The management of river stretches is carried out through a grid division of labour. "Previously, Staffing could only be notified by telephone, Level by level, and the location and situation had to be explained repeatedly during the process.. After processing and registration on the site, The driving situation was first reported by telephone and then the relevant documents were reported after returning to the station.".

In comparison, in real operation, The current process can complete task delivery in just two to three minutes, and minor anomalies can be handled in half an hour. The secret lies in the intelligent closed-loop management system.

"When an abnormal event is sent to the command center, We recover the relevant images. In minor cases, We will call them remotely to let them know to leave. If a staff needs to be on site, We can send the task to the first line. The front line can quickly understand the situation based on the information received and organize your staff to arrive on time.".

Dahua uses technology to conserve the environment, Empowering water resources with digital intelligence and helping to protect aquatic biodiversity.
