Since the development of the monitoring system, in addition to the continuous innovation of monitoring technology, monitoring products have also begun to form a powerful security monitoring system with other products. This system uses electronic fences to enclose the monitored area into a closed area. The electronic fence has a blocking and alarm system, and is a This kind of active intrusion prevention fence counterattacks the intrusion attempt, repels the intruder, delays the invasion time, and does not threaten human life. Once someone intrudes, the system starts an alarm, the monitoring system also monitors at the same time, and sends the intrusion signal to The security department monitors the equipment to ensure that managers can understand the situation in the alarm area in time and handle it quickly.
Development direction
With the development of network technology identification technology, microelectronics technology, encoding and decoding technology, operating system technology, etc., embedded technology will develop in the direction of intelligent integration, wireless, high definition, personalized interaction.
Hardware processing speed is faster and storage time is longer
With the development of chip technology, higher-performance central processing units make it faster and more powerful. From early hard disk video recorders, hard disk video recorders, hard disk video recorders, hybrid hard disk video recorders, hard disk video recorders. In addition, with the trend of high-definition, the demand for storage is also increasing, and hard disk management technology is also improving. Basically, it may support more hard disk interfaces, support technologies, and support compatibility with other storage technologies.
The encoding method is more advanced
The mainstream compression technologies on the market include. It is the most common compression method in China, and it has become mainstream as it is more suitable for network transmission requirements. In order to make embedded systems more widely applicable in the future, the unification of various algorithms will be the future development trend. However, this unification is not based on the standards of any domestic enterprise, but requires a wide range of government functional departments and industry chains. Extensive participation from all types of enterprises. For example, our country has independent intellectual property rights in compression algorithms and abbreviation algorithms, which have undergone revolutionary changes in many aspects.
Intelligence is an important development direction
From a technical point of view, intelligence is an important development direction. Only through intelligent analysis technology for video information management can people's work be freed from complicated affairs. come out. In fact, functions such as processing and retrieval of real-time monitoring and warning information require the application of intelligent technology. Although it is difficult to fully realize the management of intelligent analysis technology in a short period of time, the technology can already achieve semi-automatic monitoring intelligence to a certain extent. In most cases, most of the work can be completed using intelligent analysis technology, and staff can concentrate on In terms of management and coordination, this is a better application method at this stage. In terms of intelligence, the market demand is very strong. Many manufacturers have launched intelligent analysis technology with an accuracy that even the best intelligent analysis technology cannot achieve. The technology still needs great breakthroughs and advancements to meet market applications.
