In the era of informatization, video surveillance systems have become a crucial infrastructure and technical means for ensuring safety in production or transportation. But do you know how these surveillance devices work?

Video surveillance system is a security and prevention system based on computer technology and image processing technology. It enables real-time monitoring and recording of vital locations, thereby enhancing security capabilities. From cameras in public places to production line monitoring in industrial settings, this system finds applications across various domains.

The working principle of a surveillance system can be divided into several parts:

Data Acquisition and Processing - This component is responsible for collecting information about the monitored objects. Through cameras or other image acquisition devices, it converts on-site image signals into digital signals. It then processes and analyzes these images, enhancing their quality and clarity through adjustments such as image enhancement, noise reduction, sharpening, and contrast adjustment.

Data Storage - The processed images are stored in hard drives or network storage devices for effective management, facilitating later retrieval and playback.

Data Transmission - During playback, we rely on transmission methods like networks and optical fibers, along with devices like KVM, to convert raw data into more readable formats. This enables the transmission of images to remote control centers or other surveillance devices.

Data Display - With just a keyboard and mouse, managers can view all states of the monitored objects in real-time on a display. They can also flexibly switch between screens for more precise monitoring.

Moreover, surveillance systems can be equipped with alarm devices. In case of any abnormalities at the monitored site, these devices will immediately trigger an alarm and activate other security prevention equipment.
