Vehicle-mounted DVR recorder is a popular vehicle-mounted hard disk recorder in recent years. With the maturity and development of on-board monitoring market, the application field of on-board monitoring is also expanding. Vehicle-mounted hard disk recorders not only inherit the development direction of networking and Intellectualization Technology of ordinary embedded hard disk recorders, but also have GPS satellite positioning function and other functions that meet the customization of the transportation industry. They effectively solve the puzzles of vehicle management in different fields and departments. Therefore, they are favored by many security enterprises. With the maturity of VHDR technology, manufacturers can customize various functions according to the application requirements of different industries.
I. Application requirements of VCRs in different fields:
1. Passenger transport industry:
For the passenger transport industry, besides the simple vehicle video surveillance function, they also need wireless network video surveillance to understand the real-time situation inside and outside the vehicle, GPS satellite positioning, vehicle scheduling function, vehicle voice station, vehicle driving information recording, multimedia entertainment advertisement broadcasting and other functions.
2. Police vehicles:
For the public security industry, their main functions are video surveillance, wireless network transmission, and platform control. As for the traffic police department, more attention is paid to how to collect evidence of violation records. The main functions are license plate recognition, vehicle blacklist comparison and so on. And urban management and transportation management departments also have similar needs with traffic police departments.
3. Financial industry:
For the financial industry, such as copying vehicles, they require the vehicle-mounted video recorder to work steadily and reliably, and to transmit video information and alarm information to the management center platform in time and interact with the monitoring center platform in real time in case of emergencies.
4. Automotive Electronics:
Vehicle video recorders also need to integrate with the relevant functions of automotive electronics, such as: at present, the technology of CAN bus is widely used in vehicle driving data acquisition and upload, and vehicle video recorders should also have the function of CAN bus access and analysis and processing, recording the relevant information of vehicle driving through hard disk, and analyzing and processing important data.
5. Other means of transport:
For rail transit, shipping, aviation and other industries, they also need real-time monitoring. These industries need to increase the hard disk shock absorption and reinforcement treatment, but also pay attention to the differences between the power supply used in such projects and the power supply of ordinary cars. For example, most of the power supply for on-board equipment provided by trains is DC48V or DC110V, while the power supply for ordinary vehicles is DC12V or DC24V.
2. The application fields of VCR:
Vehicle-borne video recorders can be used in a wide range of fields, such as: public transport, long-distance passenger transport, school buses, construction vehicles, container cars, tourist buses, logistics cargo, police law enforcement vehicles, trains, subway, ships, aircraft and other mobile transport vehicles.
