Monitoring future development
May 11, 2018

Along with the network technology, identification technology, microelectronics technology, codec technology, operating systems, such as will enable the development of embedded DVR towards intelligence, integration, wireless, high motivation, personalization, interactive direction.

1. The hardware processing speed is faster and the storage time is longer.

With the development of chip technology, the higher performance CPU makes the DVR faster and more powerful. From the early CIF video recorder, to the present D1 hard disk video recorder, 960H hard disk recorder, hybrid hard disk recorder, hd-sdi hard disk video recorder. In addition, with the trend of high resolution, the demand for storage is also increasing, and the DVR hard disk management technology is also improving. Basically, DVR may support more hard disk interfaces, support RAID technology, and support the compatibility of storage technologies such as DAS, SAN and NAS.

2. The encoding method is more advanced.

At present, the compression technology used in mainstream DVR is mpeg-4, h.264, m-jpeg. Mpeg-4 and h.264 are the most common compression methods in China, and h.264 has become the mainstream because of its more suitable network transmission requirements. In the future in order to make the embedded DVR has a wider range of applicability, all kinds of algorithm will be the development trend of the future, but not the unified on the basis of which domestic enterprises standards. And need a wide range of government functional departments and the DVR and the participation of all kinds enterprise on the chain. For example, our country has the AVS compression algorithm with independent intellectual property rights, and h. 265 compression algorithm, which has a revolutionary change in many aspects relative to h.264.

3. Intelligence is an important development direction.

From a technical point of view, intelligence is an important development direction. Only through intelligent analysis technology can the information management of video be able to free people's work from complicated affairs. In fact, real-time monitoring, early warning, information processing, retrieval and other functions need intelligent technology application. Although in a short period of time is difficult to fully realize intelligent analysis technology of management, but current technology can realize semi-automatic monitoring intelligence, to some extent in most cases using intelligent analysis technology can complete most of the work, the staff can focus on management and coordination treatment, it is a good way to apply this at the moment. At present, the market demand is very strong. Many vendors now offer DVRS with smart analytics. At present, the best intelligent analysis technology is not 100% accurate, and the technology needs a great breakthrough and progress to satisfy the market application.
