The development of IP video surveillance brings the market space for the video wall. With the continuous deepening of video surveillance applications and the continuous maturation of network technologies and image technologies, video surveillance systems are entering a digital, network, and large-scale era. From the first generation of CCTV analog video surveillance, the second-generation local digital storage service-based DVR system to the current third-generation network video surveillance system, video surveillance has gradually transitioned from isolated and simple small-scale application systems to interconnection and integration. Large-scale management system. The huge system architecture and complex data services make more demands on the stability, security, and intelligence of the monitoring system. For large screen video wall systems, in addition to the above requirements, there are special requirements for the display speed, video stream processing capability, and the number and flexibility of IP signal access. IP video surveillance calls for intelligent, high-definition, networked Mosaic display wall.

The all-digital intelligent monitoring system begins with digitization and standardization from the front-end video signal source. Combining advanced computing technology, data management, and switching technology, the video imaging system becomes an important resource, with IT systems, operations (production) management systems, and security ( Preventive) systems, other application systems to achieve a seamless connection to achieve unified management and control purposes. The integration and development of image resources is an important feature of the new generation of IP video surveillance systems. It uses the non-linear data such as video surveillance images to perform in-depth mining, scale, systematization, and platformization to provide development for different types of business applications. Resources. Front-end integration, access diversification, video digitization, system networking, and management intelligence are the recognized development directions of video surveillance systems. Digitalization and networking are the two most basic prerequisites.

The DLP splicing system has entered the professional control room market for more than ten years and has a leading edge in display technology. Its display screen is rich in colors, reproducible and realistic, the system is low in environmental protection, and it is safe and stable. It has been widely recognized in the video surveillance market. At present, more and more DLP professional display systems are used in video surveillance centers. From the commonly used monitor groups to the video wall to today's DLP digital video wall, the brief and rapid development process tells us that video surveillance has also achieved a transition from analog to digital to today's all-digital evolution.
