Automobile DVR
A car DVR (Digital Video Recorder) is an emerging specialized product that falls under the subcategory of traditional embedded hard disk recorders. It has developed by applying digital audio and video encoding technology to vehicles. Car DVRs utilize embedded processors and embedded operating systems, integrating the latest H264 audio and video compression/decompression technology, GPS global positioning technology, 4G wireless communication technology, USB communication technology, advanced car power management technology, and GIS (Geographic Information System) technology. They are suitable for 24-hour monitoring of various vehicle types.
Car DVRs feature synchronized audio and video recording, global positioning, and real-time wireless audio and video transmission. They can connect to in-vehicle devices such as display screens, IC card vehicle machines, signal priority control systems, and passenger flow statistics systems through various reserved interfaces. These DVRs are widely used in public transportation, long-distance buses, school buses, engineering vehicles, container trucks, tour buses, logistics vehicles, police vehicles, trains, subways, ships, airplanes, and other mobile transportation tools.
Currently, the audio and video codec algorithms used by car DVR manufacturers mainly include MPEG2, MPEG4, H264, and MJPEG. Among these, MPEG2 and MJPEG have lower compression rates and are less frequently used. The H264 codec algorithm, with its high video compression rate, low bit rate, and good adaptability to low-bandwidth wireless networks, is the preferred compression format for car DVRs today.
