Analysis of Six Major Trends in the Development of Modern Security Monitoring

The development trend of modern security monitoring is digitalization, networking, integration, intelligence, and standardization. Advanced security technology has continuously penetrated into various industries and has formed distinctive applications in different industries.

Digimonization began with digital video surveillance (DVR), a typical product representative for digital surveillance. The concept of digital surveillance has begun to take root and digital hard disk recorders have evolved into smart digital surveillance consoles today.

Networked network digital audio and video servers (DVS), IP cameras, network digital hard disk recorders (NVR), etc. These products are all closely related to network applications. The direct result of front-end digitization is the networking of transmission and back-end applications. More and more systems emphasize network applications. The networkization of the system has to some extent broken the geographical and quantitative boundaries of deployment areas and equipment expansion.

In the past, we also saw the basic linkage between the anti-theft alarm system and the video surveillance system provided by different manufacturers, but it has never been as good as today's integration integration. The integrated platform software uses serial ports, buses, networks, and other interfaces and software technologies. , can well integrate various products together.

Intelligent, complex and flexible alarm linkage strategy, intelligent video analysis, image pattern recognition, and image motion detection are examples of intelligent development.

Standardized video compression processing generally follows MPEG2, MPEG4, H. 264 and other standard specifications, audio compression processing generally follow the G711, G723.1 and other standard specifications, cloud mirror control also has a well-known brand manufacturers standard protocol, the formulation of more standards, is conducive to the interconnection of different manufacturers' products.

Streaming media monitoring technology Streaming media technology adopts stream technology, that is, continuous video and audio information are compressed and processed, and multimedia information is transmitted and played on the network in real time. After the compressed and composite multimedia data, it is necessary to adopt streaming media technology to carry out reliable real-time transmission on the network. The key technology implemented by streaming media is streaming, which continuously transmits multimedia information from the audio and video server to the user terminal in real time. The multimedia information data of such a streaming system is parsed into a compressed package by a specific compression method, and is transmitted to the user terminal in sequence or in real time by the streaming media server, and the user can watch only after a delay of several seconds.

In large-scale network monitoring systems, it is often necessary to adopt streaming media transmission and streaming media distribution technologies to implement distributed network monitoring applications and avoid network bottlenecks caused by concurrent traffic. Streaming media monitoring technology through a number of streaming media technology to complete the network video surveillance applications, through the effective streaming media network management network to achieve a reasonable use of large-scale video network monitoring provides a solid technical support.
