Introduction:Traditional surveillance systems have evolved from analog to digital over time. While early analog systems had limitations in terms of monitoring range, switching capabilities, and data storage, the subsequent digital systems improved functionalities and ease of operation. However, stability issues and complex wiring persisted, and the monitoring range remained limited. In contrast, the latest smart video surveillance systems have overcome all the shortcomings of their predecessors and demonstrated significant superiority. Leveraging internet platforms, digitalization, and informatization, smart video surveillance technology utilizes computer vision to intelligently analyze and process video, enabling fully automated monitoring under unmanned conditions....

Traditional video surveillance technology has long been plagued by various limitations. Passive in nature, these systems offer synchronous monitoring and remote control, enabling the retrieval of footage for playback after an event. Lacking intelligent features, these systems necessitate real-time monitoring by human operators, who analyze events and trigger alarms based on their judgment. However, as surveillance devices and targets increase, the volume of monitoring data grows exponentially, stretching human capabilities beyond their limits. Achieving comprehensive real-time monitoring becomes challenging, let alone making timely judgments and issuing alerts.Furthermore, the rapid expansion of video data places significant burdens...

Surveillance systems have become an essential part of ensuring security and safety in various settings, including homes, businesses, and public spaces. These systems rely on advanced technology to monitor and record video footage, providing real-time displays, video playback, and recording capabilities. In this article, we will explore the key components that make up a surveillance system and their respective functions.System Main Components:1.1 NVR (Network Video Recorder):The NVR is a crucial element of the surveillance system. It serves as the central hub for processing and storing video images captured by the network cameras. Equipped with high-capacity hard...
