Principles and Application Scenarios of Fisheye Surveillance Cameras

Fisheye surveillance cameras utilize lenses with focal lengths of 1.28mm, 1.67mm, or even shorter. They typically offer a field of view exceeding 180 degrees, producing circular images where vertical lines appear curved and significant image distortion occurs; they are primarily used for wide-area surveillance. This is an emerging surveillance mode in the video monitoring sector. While monitoring an entire scene using multiple standard cameras can make tracking a moving object difficult due to poor continuity between feeds, fisheye cameras solve this problem by capturing the whole area in a single view.
Application Scenarios for Fisheye Surveillance Cameras:
1. Situations requiring a comprehensive overview of a location without the need for fine detail, such as large public spaces, transportation hubs, and traffic intersections. A single fisheye camera installed at a high vantage point can provide the necessary panoramic coverage for the entire site.
2. Environments where both detailed monitoring and "blind-spot-free" coverage are essential, such as banks, supermarkets, and shopping malls. These locations are prone to security incidents like robberies and theft, where tracking a suspect's movements is critical.
3. Scenarios requiring both a panoramic overview and the ability to highlight specific incidents or trigger early warnings and retrieve footage of events. This approach combines panoramic capabilities with the ability to focus on key details—a distinctive feature that balances effective surveillance with cost-efficiency.
