[0002] With the deep integration and innovative application of next-generation information technologies such as artificial intelligence, big data, and the Internet of Things, modern security monitoring systems have achieved a leapfrog development from traditional passive defense to proactive intelligent perception. Their application boundaries are constantly expanding, deeply penetrating key areas such as smart city governance, intelligent traffic control, and public safety early warning. The system architecture adopts a modular design, consisting of front-end sensing devices with edge computing capabilities and a cloud-based intelligent analysis platform. High-performance network cameras paired with intelligent zoom lenses serve as visual sensing terminals, undertaking the core function of multi-dimensional environmental information collection.

[0003] However, traditional surveillance solutions are generally limited by the inherent limitations of mechanical structures, resulting in systemic defects such as fixed monitoring angles. This leads to dynamic blind spots in the surveillance network, making it difficult to meet the high standards of modern security systems that require full coverage, real-time tracking, and intelligent early warning. This contradiction between static monitoring modes and dynamic security needs is becoming increasingly prominent, especially in complex urban scenarios. Utility Model Content

[0014] 1. This adjustable-view camera monitoring system, through its adjustable structure, employs a worm gear transmission mechanism in conjunction with a high-precision motor drive to ensure the stability and positioning accuracy of the camera's horizontal rotation, effectively overcoming the backlash problem inherent in traditional pan-tilt mechanisms. The gear and rack mechanism, along with the electric push rod, enables stepless adjustment of the pitch angle. Precision guidance from the guide frame ensures the linearity and repeatability of the angle adjustment. The optimized combination of the circular guide rail and the rotating frame not only provides stable rotational support but also enhances coverage. The modular transmission structure design significantly improves the system's reliability and maintenance convenience while reducing operating noise.

[0015] 2. This adjustable-view camera monitoring system, through its lifting structure and precision transmission system, achieves precise vertical positioning of the monitoring camera. Its core advantage lies in its composite transmission scheme using pulley drive and lead screw guide rail, ensuring both smooth power transmission and millimeter-level accuracy in height adjustment. The optimized transmission block and sliding frame structure effectively reduces frictional resistance, making the lifting process smoother and quieter. The combination of a rigid support frame and precision lead screw significantly enhances the mechanism's load-bearing capacity. The modular height adjustment unit and rotating mechanism work together to achieve comprehensive three-dimensional coverage of the monitoring system. The intelligent motor drive system, combined with high-precision transmission components, enables the camera to quickly respond to height adjustment commands, significantly improving the efficiency and accuracy of monitoring angle adjustment, and providing a reliable mechanical solution for comprehensive monitoring needs in complex scenarios.
