Located in Budai, Chiayi, the migratory bird wetland is a peaceful ecological park. Many bird species and their symbiotic plant and animal communities reside and thrive here, forming a vast ecosystem. In the southern Budai Wetland, one can spot various bird species, including the Black-faced Spoonbill, the White Spoonbill, and the Red-billed Gull, attracting numerous visitors and birdwatching photographers.
Given its expansive size, covering 1,385 hectares, managing the park purely by manpower is difficult and impractical. Over-reliance on human resources could disturb the fragile ecosystem. Moreover, when deploying cameras to monitor the area, a different approach must be taken due to the unique characteristics of the site.
Firstly, due to the special nature of the site, the camera deployment needs to be strategic, with a focus on coverage rather than density. Excessive camera installations would waste resources and pose maintenance challenges. To achieve extensive coverage, PTZ (Pan-Tilt-Zoom) rapid dome cameras are the optimal solution, as they offer both broad and long-distance coverage.
One of the key features and advantages of PTZ cameras is their high optical zoom capabilities. In collaboration with the park, LILIN deployed PTZ cameras with up to 40x optical zoom, and their infrared projection can reach up to 800 meters at night, fully addressing the park’s requirement for no light pollution while enabling nighttime surveillance.
What tasks do the park's monitoring systems need to fulfill? In addition to standard surveillance recording, most of the wetland area consists of ponds that are off-limits to personnel. The cameras assist in establishing electronic fences and utilizing personnel recognition features to trigger alerts when individuals cross designated boundaries. Observing birdlife is another crucial task, as the intelligent PTZ cameras can be trained to identify bird species. They can count the number of birds in different areas at various times, with the data transmitted to the backend database for further analysis and application.
"A single PTZ camera can replace several traditional cameras, which is one of its strengths," said Steve Hu, Chief Information Officer at LILIN. "The 40x optical zoom PTZ camera is rare in the market, and with infrared capabilities reaching 800 meters and intelligent monitoring features, we are confident that this product is well-suited for this specialized application."
Cameras are not just for monitoring; they can also aid in ecological management, exemplifying the positive role surveillance equipment can play. Intelligent cameras are capable of recognizing not only humans but also animals, offering a wide range of applications, such as detecting animal intrusion along defined paths. These solutions are not only feasible but have already been successfully deployed in real-world scenarios.
