What are the functions of car DVR?
Car mounted hard disk recorders are a very practical existence. It is similar to video surveillance. It can record the situation of passengers and drivers during driving by installing an onboard hard disk recorder. If there are any special circumstances, the recorder can be adjusted. Understanding the situation at that time, what exactly is a car DVR? What does it do?
What is an in car DVR?
The vehicle system is divided into three parts: front-end vehicle monitoring system, communication link, and monitoring management platform.
Front end vehicle monitoring system: including onboard hard disk recorder, monitoring camera, alarm button, LCD display screen, intercom earphones, speakers, GPS, 3G communication module (EVDO/WCDMA/TD-SCDMA), etc.;
Communication link: including 3G wireless network, WIFI wireless network, and backend command center Ethernet;
Monitoring and management platform: includes a series of service groups such as monitoring equipment and GPS map positioning, streaming media, databases, application servers, etc. It can build a multi-pole monitoring platform in the group company, traffic management bureau, and other units as needed, and can flexibly configure logical relationships between levels according to needs. The system has good scalability.
Vehicle mounted DVRs belong to the segmented market of traditional embedded DVRs. It is an emerging specialty product developed with the application of digital video and audio encoding technology in automobiles. The vehicle mounted hard disk recorder combines advanced technologies such as digital video and audio codecs, high-capacity data hard disk storage in harsh environments, automotive electronics, wireless video network transmission, GPS satellite positioning, etc., achieving video and audio monitoring in the passenger transportation industry, special vehicle industry, and other related fields.
Car mounted hard disk recorder is a specific application model of hard disk recorder in the transportation field that has emerged in recent years. It adopts the same video capture and compression methods as ordinary hard disk recorders, but due to different functional and environmental requirements. Due to its special design requirements, it requires the addition of many special designs, such as shock resistance, voltage stabilization, and anti-interference. The car mounted digital hard disk recorder mainly has functions such as monitoring, recording driving status, entertainment, advertising, etc.
