Overview
\nCar Recorder belongs to the segment of traditional embedded DVR. It is a new type of specialized product developed by combining the application of digital video and audio coding technology in automobiles. It adopts embedded processor and embedded operating system, combined with the latest
\nH.264 audio\/video compression\/decompression technology, GPS global positioning technology, 3G wireless communication technology, USB communication technology, advanced vehicle power management technology in IT field, and GIS geographic information technology, which is suitable for 24-hour monitoring of all kinds of vehicles. It can perform audio and video
\nfrequency synchronous recording, global positioning, and wireless audio and video real-time transmission. At the same time, a variety of interfaces are reserved on the upper computer, which can be connected with vehicle display, IC trucks, signal priority control system, passenger flow statistics system and other vehicle equipment. It is widely used in public transportation, long
\ndistance passenger transportation, school buses, engineering vehicles, container trucks, tourist buses, logistics and freight transportation, police law enforcement vehicles, trains, subways, ships, airplanes and other motor vehicles.
\nAt present, each vehicle DVR DVR manufacturers choose the main video and audio codec algorithms: MPEG-2, MPEG-4, H.264, MJPEG, etc., of which MPEG-2 and MJPEG compression rate is lower and less used; H.264 coding algorithm has a video
\nvideo compression rate is high, the code rate is low, low-bandwidth wireless networks adaptable to features such as good. H.264 coding algorithm is characterized by high video compression rate, low bit rate and good adaptability to low bandwidth wireless network. With the improvement of digital coding performance, the video resolution of car DVR is also upgraded from CIF (352×288) to
\nD1 (704×576).<\/p>","protected":false},"excerpt":{"rendered":"
