Market segmentation, vehicle monitoring function

With the substantial increase in vehicles, the market's demand for vehicle monitoring and management systems has also risen significantly. We mentioned earlier that vehicle video monitoring will become a trend. Now let's talk about the functional characteristics of the car monitoring system, which makes him very popular. Vehicle monitoring ???1. The monitoring center can remotely monitor the vehicle video in real time, and supports monitoring through a variety of terminals, mainly including PC and other clients, TV walls, mobile phone terminals, and has remote video browsing, remote control, multi-screen monitoring, multi-screen polling, Manual recording, video playback and other functions. (1) Monitoring client The monitoring center is connected to the telecommunication IDC room through a dedicated line, and customers can browse video surveillance and camera PTZ control functions of each monitoring point. (2) Large-screen TV wall Can install network video decoder to decode the digital signal collected by the front end into images and sound and transmit them to the TV wall, providing users with centralized real-time display of multi-channel monitoring point images. (3) Mobile phone monitoring Realize remote video browsing, remote cloud mirror control, video screenshot and other functions through the 3G mobile terminal with built-in monitoring client software to meet the needs of customers' remote video viewing and remote emergency command, and provide 3G customers with video surveillance services anytime, anywhere. 2. Video storage and playback ' Adopt multi-level storage structure, there is on-board hard disk, storage CIF (D1), wireless upload CIF in the compartment. Car video can be queried and downloaded remotely. Video playback 3. Car alarm linkage On-board alarm linkage mainly includes one is an external alarm button, that is, the driver can alarm the monitoring center in case of emergency during driving. The second is two-way voice communication. Built-in GPS can track the vehicle's trajectory, can fully understand the operation situation. In addition, vehicle monitoring has some other features. One is distributed monitoring, centralized management, intelligent setting, and humanized operation. The second is the integrated design of wireless video server, with high system reliability. The third is the use of dual-stream technology, local recording uses D1 resolution, network transmission uses CIF / QVGA resolution. The fourth is to adopt H.264 compression coding mode, support multiple channels of video access at the same time, each channel of video in 8 ~ 10 frames, the video is clearer. Fifth, wireless network transmission, China Telecom's 3G upstream bandwidth can reach 1.8Mbit / s. Sixth, the system has strong expansion capabilities. It is worth noting that the demand for comprehensive monitoring by users is increasing. These functions can no longer meet the needs of customers. Therefore, the development of new, multi-functional, and intelligent vehicle monitoring products to meet new user needs has become Now an important issue for various manufacturers.
