More accurate positioning, car video recorder enters the era of customization

Car hard disk video recorder (Car DVR) Belonging to the market segment of traditional embedded hard disk video recorder, it is a new special product developed with the application of digital video and audio coding technology in vehicles. According to the analysis of the five application requirements of vehicle DVR, at present, there are various kinds of vehicle DVR (Car DVR) , As a market segment of traditional embedded hard disk video recorder, car hard disk video recorder (Definition of vehicle-mounted hard disk video recording)It has also welcomed the favor of many security enterprises. The vehicle-mounted hard disk video recorder can be customized with various functions according to the application requirements of different industries. 1. Analysis of police vehicle customization function. The main functions of the public security industry for vehicle-mounted hard disk video recorders include video monitoring, wireless network transmission, pan-tilt control, etc. The traffic police are more concerned about how to carry out illegal evidence collection. The main requirements are: license plate recognition, Blacklist comparison, etc. Industries such as urban management and transportation management also have similar needs as traffic police. 2. Analysis of customized functions in the passenger transport industry.

For the application of vehicle-mounted hard disk video recorders by other means of transportation, rail transit, ships, aviation and other industries also have real-time monitoring requirements. In addition to adding shock absorption and reinforcement treatment for hard disks, attention should also be paid to the difference between the power supply used in such projects and the power supply of ordinary automobiles. For example, the power supply of on-board equipment provided by trains is mostly DC48V or DC110V, while the power supply of ordinary on-board equipment is DC12V or DC24V. 5. Automobile electronic customization function, vehicle-mounted hard disk video recorder should also be combined with relevant functions of automobile electronics, for example: CAN bus technology is widely used in automobile driving data collection and uploading, vehicle-mounted hard disk video recorder should also have CAN bus access and analysis and processing functions, record relevant information of vehicle driving through hard disk, and analyze and process important data.
