An Overall Expertise in Electronic Mobile DVR

Basics of Sdcard Electronic Mobile DVR The Electronic mobile DVR is one of the traditional embedded DVR niches, it's an emerging products developed for vehicle applications as digital video and audio encoding technology. It uses the embedded processor and embedded operating-system, and combines with all the latest H.264 car stereo compression or decompression technology, GPS navigation technology, 3G wireless communication technology, USB communication technology, advanced vehicle power management technology and GIS geographic information technology, it's well suited for all kinds of car models for 24-hour surveillance. Car stereo sync video, gps, wireless video and audio real-time transmission are available, at the same time, the host put aside a variety of interfaces, it might interact with the auto display, IC card-board machine, signal priority control systems and passenger car statistical system devices. Nowadays, SD Card Mobile DVR are traditionally used in mobile transports like public transport, long-distance passenger transport, tourist bus, logistics and freight forwarding, police enforcement vehicles, trains, subways, ships, aircraft and so on. Storage Mode of Mobile DVR Presently, the mobile DVR has three storage means, they may be hard disk drive, U disk and Facts. Electrical systems, longevity of U disk is higher. 1, U disk doesn't have mechanical moving parts, low power consumption, you can use within the severe and harsh power environment. During these car, the normal Sdcard mobile DVR cannot work effectively; 2, Convenient transcription data, the U disk could be directly attached to your computer USB interface, it is possible to playback video, save video and without hard disk connector and USB adapter, easier operation; 3, U disk interface design is acceptable for repeated mating plus more reliable compared to the Sdcard. Facts interface will be the interface equipment, it's not at all ideal for regular plug as well as the damage minute rates are quite high. Wide Putting on Mobile DVR Up to now, the video and audio codec algorithms of most mobile DVR manufacturers choose are: MPEG-2, MPEG-4, H.264, MJPEG, etc., included in this, compression ratio of MPEG-2 and MJPEG is low, seldom used in usual time; while the H H.264 encoding algorithm gets the characteristics of high video compression rate, low stream, wireless networks low bandwidth adaptability it's now the optional compression format direction of mobile DVR. Mobile DVR, using the increase a higher level social recognition, the requirements of various different mobile DVR levels also appear. With the constant improvement of their function, its application scope can become an extremely widespread and growing role, not only will it employed in the long-distance bus, and also will be traditionally used in accordance buses. mobile video recorder can play a huge role in the civilized society.
