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, you can adjust the video screen of the recorder to understand the situation at that time. What is a car mounted hard disk recorder?

The onboard system is divided into front-end onboard monitoring system, communication link, and monitoring management platform.

Front end car monitoring system: including car 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 Ethernet in the backend command center;

Monitoring management platform: includes a series of service groups such as monitoring equipment and GPS map positioning, streaming media, databases, application servers, etc. It can be built as a multi-pole monitoring platform in the group company, traffic management bureau, and other units as needed. The logical relationships between levels can be flexibly configured according to needs, and the system has good scalability.

Car mounted hard disk recorders belong to the segmented market of traditional embedded hard disk recorders. It is a new specialized 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 encoding and decoding, large capacity data hard disk storage in harsh environments, automotive electronics, wireless video network transmission, GPS satellite positioning, etc., to achieve 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 in recent years. It uses the same video capture and compression methods as regular hard disk recorders. However, due to differences in functional and environmental requirements, car mounted hard disk recorders have special design requirements that require the addition of many special designs, such as vibration 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.
