Description

Technical Field

[0001] This utility model relates to the technical field of security cameras, specifically to an intelligent security camera. Background Technology

[0002] Social security threats are complex and diverse, and traditional security methods are insufficient to meet security needs. Intelligent security cameras can proactively identify and warn of security threats, ensuring the safety of people and property in various scenarios. Currently, in the field of security camera technology, some traditional devices have numerous limitations. Regarding image acquisition, some cameras have low resolution and frame rates, making it difficult to capture clear and smooth monitoring images, leading to the loss of crucial details, such as the inability to accurately identify facial features or changes in object shape in complex scenes. In the intelligent processing stage, weak computing power prevents the rapid and accurate analysis of image and sound data. When faced with complex behavioral patterns or abnormal audio, false alarms and missed alarms occur frequently, significantly impacting monitoring reliability. At the network transmission level, some cameras use outdated protocols with narrow bandwidth and poor stability. During long-distance transmission, video stuttering and data packet loss are severe, making it difficult to meet real-time monitoring requirements. Utility Model Content
