Urbanization rapid development of mobile video monitoring bottleneck needs to be solved

With the rapid development of urbanization, people's security awareness has been continuously strengthened, and the demand for the emergency communication industry has become increasingly strong, and their technical and functional requirements are also increasing. Therefore, many aspects of mobile video surveillance have become an urgent problem to be solved, such as how to improve network broadband, transmission stability, video storage space, enhance data protection, and protect user privacy. We will analyze it carefully.

Data transmission aspect

Since the effective bandwidth of a single terminal of the public data communication network is quite effective, the 3G network can transmit the D1 format video of the low code stream in the transmission of voice and data services, and the bandwidth of the 4G network is greatly improved, and the 720P HD video is basically satisfied. In addition, when the device is in the mobile state, the broadband decreases with the increase of the moving speed, the available bandwidth is easy to fluctuate, the high-bandwidth video monitoring data is easy to be lost, and the reliability is not high. In order to avoid the above problem of data transmission, efforts can be made from various aspects, such as improving the video coding algorithm, adopting an efficient video compression ratio, improving the re-error correction capability of the video transmission, and providing a re-recovery algorithm for the transmitted error data.

2. Network security aspects

Security is the cornerstone of the mobile Internet, and it is the life of video surveillance. Video surveillance was originally designed for security. Hackers illegally acquire or interrupt surveillance images by means of interception, especially in politics and law. In special areas such as finance, it will pose a serious threat to security. Therefore, network security is also a resistance to mobile video surveillance.

Compared with the limited transmission mode, the information of the open wireless transmission mode is more easily stolen. The mobile video surveillance usually strengthens the security by means of data encryption, so the security of the system and the strength and key of the encryption algorithm are very Big relationship. If a malicious attack is received and the wireless signal is intercepted, the content transmitted through the wireless is exposed to the attacker's line of sight, so the video transmission must have an anti-theft function.

3. Storage aspects

When data is aggregated to the center or stored at various nodes, the pressure on the central ingress bandwidth and storage capacity are a challenge. In the short term, distributed storage will also be the mainstream choice. For users, the value utilization of basic data is very low. If intelligence can help users extract the most valuable data from users of massive audio and video data, this will be Partial data is stored centrally, which can also greatly reduce the pressure and storage capacity of the central entrance bandwidth. Cloud storage has the characteristics of large capacity, convenient storage and fast storage. In terms of mobile video surveillance, it can watch video anytime and anywhere, and it will not be lost like local storage, and can realize functions such as online editing and video sharing.

4. Carrier fee

For some mobile monitoring systems that need to work without downtime, the huge amount of data will generate high traffic charges, and the high cost will affect the application range of mobile video surveillance in the future. Therefore, the mobile video surveillance service is further assisted in retreating from the market, and the package mode is flexibly formulated according to the needs of different target customer groups.

5. Standard construction

Although the security industry has been accelerating the pace of opening and consolidating in recent years, there is still a certain distance in the mobile security field compared with the open compatibility of the communications industry.

6. Network costs

Although the network charges of 3G and 4G have been reduced, the real-time preview and return visit of the mobile phone network provided by the operator will still generate unacceptable traffic charges. These will limit the development of mobile video surveillance.

7. Technical limitations

Mobile video surveillance has gradually become the mainstream surveillance in the security market, and its share is increasing. However, most merchants find that customers have higher and higher requirements on hardware, and the requirements for software, especially video analysis, are getting higher and higher. This requires the transformation of the business, from a single device provider to a solution provider.

Based on the original hardware equipment provider, Tengyuan Zhituo has successfully upgraded to a mobile surveillance video solution provider. Under the premise of strengthening the performance of hardware devices and developing new application scenarios, Tengyuan has independently developed applicable software devices to enable Tengyuan. Zhituo has become an integrated mobile monitoring system integrating video capture, wireless transmission, video intelligent analysis and background multi-form display.
