Three major trends of video surveillance matrix

With the emergence of large-scale construction projects such as “Safe City”, the matrix network cascading system consists of a central matrix and multiple matrixes of nodes. Each matrix has an independent IP address and exchanges data through the Ethernet port. The development of high-definition matrix is ​​increasingly prominent. After the high-definition matrix, whether it is networked or stand-alone operation, retains the original convenient switching control, image inspection positioning and other functions, such as alarm linkage, group switching and so on. As a result, the development of matrix technology is moving toward compatibility. Similarly, the combination of hardware and software will shape the future direction of video matrix.

High-definition direction

Now that the market has become diversified, the traditional matrix has not been able to meet the needs of the market. Today, the hybrid card matrix is ​​flexible, easy to switch, and has a wide range of applications. A good card matrix must have fast switching speed, easy card replacement, superior image processing performance, simple operation, and compatibility with other control devices. In these card matrixes, PMT's MMX series card matrix switching speed has obvious advantages in similar products. It adopts hot-plugging technology design to ensure that any change of video card can be done under any circumstances. Will affect the use of products and effects, using the most advanced international video processing chip to ensure the image effect.

The appearance of the hybrid card matrix in a great sense solves the problem of conversion of analog video signals and digital video signals. The analog signals are generally quantized into digital signals by the PCM pulse code modulation method, that is, the different amplitudes of the analog signals correspond to different ones respectively. Binary values, which translate into computer languages ​​that the machine can recognize. The principle is roughly the same, and the method of processing is also diverse and has its own characteristics. At the same time, the compatibility between different video signals is also a technical problem. For the HDMI signals and the HD-SDI signals that are the same as the HD signals, the compatibility of the signals is a big problem. PTN's MMX series products are compatible with a variety of signal formats at the same time, can complete the conversion between analog signals and digital signals. At the same time, in the process of converting analog signals into digital signals, due to its own lack of resolution, PTN built-in international first-class The scale processing chip can guarantee the converted video effect.

To seize the market, hard work must be done. Products must have unique design concepts and very complete product functions. This is the prerequisite sword. With the development of the market and people’s demand for products is getting higher and higher, the products need to be constantly The innovation, walking in the front of the customer, the traditional function of the matrix can not meet the requirements of the market, the large-screen segmentation and splicing function is increasingly recognized by the market.

Increased compatibility

With the emergence of large-scale construction projects such as “Safe City”, the matrix network cascading system consists of a central matrix and multiple matrixes of nodes. Each matrix has an independent IP address and exchanges data through the Ethernet port. The node matrix uploads the local video output to the center matrix, and the center matrix can switch and control the images of all the node matrix cameras. By adding the central matrix to the video downlink channel of the node matrix, each node matrix can implement interconnection and control and cross-regional scheduling.

After the high-definition matrix, whether it is networked or stand-alone operation, retains the original convenient switching control, image inspection positioning and other functions, such as alarm linkage, group switching and so on. Therefore, the technical development of the SDI matrix must be toward the development of metropolitan area, networking, integration, fiber optics, digitization and wide compatibility. Unicom can be accessed for legacy systems. And can be based on the SDI matrix software management platform under the unified management of storage, control, communications, images, and early warning, to achieve the full range of digital city management functions.

Future Development: "Soft and Hard" Combination

In the future, the competition points of various matrix manufacturers will focus on the provision of the overall solution for the industry market, as well as core technologies and sales channels. At present, the application of HD-SDI matrix is ​​relatively simple, and hybrid matrix is ​​better than hot-selling. However, in the long-term situation, this situation is only temporary. The number of domestic HD-SDI vendors is increasing, but the level of technology varies greatly. Many manufacturers are taking the overall solution route and providing engineering services and users with customized services.

As far as the current market application is concerned, video surveillance is developing in the direction of high-definition, networking, and digitization. The application of HD-SDI matrix is ​​booming. On the contrary, the application of HD-SDI matrix can be described as the tip of the iceberg. Although the analog matrix still occupies a larger seat, with the maturity of video high-definition technology, HD matrix will eventually have its own world. The future high-definition matrix will continue to play an important role in video surveillance, and more computer technologies and network technologies will be integrated into the HD matrix. "The future development of the HD-SDI Matrix is ​​easy to control, intelligent, and automation will be a trend, and on the basis of realizing high-definition and real-time images, it will enable remote management and multi-level cascading control via the network." Shenzhen Infinova Extension Marketing Department Manager Zhao Xiaohui said.
