Vehicle surveillance is a new type of video surveillance equipment specially designed for the field of vehicle security. What is the function of on-board monitoring? The following edition will introduce the function of on-board monitoring to you.
Vehicle Monitoring Function
The monitoring center can monitor vehicle video remotely and in real time. It supports monitoring through various terminals, including PC client, TV wall and mobile terminal. It also has functions of remote video browsing, remote control, multi-screen monitoring, multi-screen polling, manual video recording and video playback.
(1) Monitoring client
The monitoring center is connected to the telecommunication IDC computer room through a dedicated line. Customers can browse the video of each monitoring point and control the PTZ of the camera.
(2) Large screen TV wall
Network video decoder can be installed to decode and restore the digital signal collected from the front end to image and sound transmission to the TV wall, providing users with a centralized real-time display of multi-channel monitoring point images.
(3) Mobile monitoring
The functions of remote video browsing, remote cloud mirror control and video screenshots are realized through the 3G mobile terminal with built-in monitoring client software, which meets the needs of customers for remote video viewing and remote emergency command, and provides video surveillance services to 3G customers anytime and anywhere.
Video storage and playback
The multi-level storage structure is adopted. There are on-board hard disk, storage CIF (D1) and wireless upload CIF in the carriage. Vehicle video can be queried and downloaded remotely.
On-board alarm linkage
The on-board alarm linkage mainly consists of an external alarm button, which means that the driver can alarm the monitoring center in case of an emergency in the course of driving. Second, two-way voice calls.
The built-in GPS can track the vehicle's trajectory and fully understand the operation situation.
Above is the function introduction of on-board monitoring, you can know about it. In addition, there are other characteristics of on-board monitoring. One is distributed monitoring, centralized management, intelligent settings and human-based operation. Secondly, it adopts the integrated design of wireless video server, which has high reliability. Thirdly, dual bit stream technology is adopted, D1 resolution is used for local video and CIF/QVGA resolution is used for network transmission. Fourth, H. 264 compression coding is adopted to support multiple video access at the same time, each video in 8 to 10 frames, the video is clearer. Fifth, wireless network transmission, China Telecom 3G upstream bandwidth can reach 1.8 Mbit/s. Sixth, the system has a strong ability to expand.
