Each part of the vehicle DVR is integrated on the main board. Unlike ordinary security surveillance video recorders, it has good adaptability to harsh environments such as low-frequency vibration and dust. 
To be a stable car DVR, in addition to a stable operating system, you must solve the following problems:
1. Stable wide voltage, unstable voltage on the vehicle, fueling valve, battery aging and other operations will affect the voltage fluctuation of the vehicle, up to 6V, up to 70V. Car DVRs that do not have super-wide voltage can not work normally in the car. They often crash, do not record, and seriously burn the motherboard, power board, camera or even other equipment on the car. The car DVR does a lot of work on the power supply. The machine can work normally from 7V to 40V, and has a stable 12V/4A voltage output for cameras and car displays. We believe that the voltage of 6V to 70V will not affect our machine. We welcome the test and we are responsible for any problems.
Professional anti-shock treatment, the main focus of the car is low-frequency vibration, most of the cars are mainly 20HZ-40HZ vibration, the anti-shock treatment will cause the car DVR to crash, restart, the hard disk does not work, lost video segments and other issues. Liyan Car DVR has done a very professional treatment on the shockproof, mainly from two aspects: First, the hard disk and the shockproof silicone pad of the whole machine are self-opening design, with anti-low frequency vibration, and the welding board is welded. Plug the cable, all cable connectors are locked. Second, the software, the independent research and development of vehicle DVR software has MPFS (multiple protected file system) file system and data high error correction.
Suitable for the structure of the machine on the car, the environment in the car is bad, heat dissipation, dustproof, waterproof, anti-folding, anti-pressure is a problem that must be considered. Car wash may allow water to enter other equipment on the car. Drivers, ticket sellers, passengers and other personnel may damage the machine, such as folding, smashing, pressing, etc., the recorder will generate a lot of heat, and a lot of dust will be generated on the car. These problems will affect. The normal operation of the vehicle DVR, if any of these problems are not handled and resolved well, will be an unqualified vehicle DVR. The vehicle DVR has designed an in-vehicle DVR chassis according to the actual situation of the car. The chassis is made of solid steel plate. There is no detachable wire on the exterior after locking. The front and rear shutters are used for ventilation and heat dissipation. The internal vehicle DVR casing is made of all-aluminum profiles. The machine adopts a vortex vent to function as a chimney pipe, and the aluminum plate on the main board is dust-proof and heat-dissipating.
4, convenient management, a large number of vehicles, a large number of video data per car, if you can not find it convenient and quick to find, read, will cause a lot of personnel and time for the user to manage. The video files of Liyan Car DVR are compatible with FAT32 format. The data can be read directly on the computer through the hard disk reader. The file name of the video data is named by date, time and license plate number. The license plate number, time, GPS information and Date, support CF card recording and data copy.

Functional analysis of car DVR
[ Huaqiang Security Network News ] The car DVR adopts the embedded operating system, and its system is perfectly combined with the operating system of the DVR . It directly calls the hardware, speeds up the reaction time, improves the running speed and reduces unnecessary extras. Features. The vehicle DVR has high anti-virus performance. Due to the use of professional software and hardware, the data stored in the chip is read-only, non-writable, and the software has very few accompanying functions, and the virus cannot be invaded.
