Liyan Car DVR( Vehicle 3g Gps Tracking Camera supplier ) adopts an embedded operating system. Its system is perfectly combined with the operating system of the hard disk video recorder. It directly calls the hardware, speeds up the reaction time, improves the operating speed, and reduces unnecessary extra functions.
All parts of the Dangyan vehicle-mounted DVR are integrated on the main board, which is different from general security monitoring video recorders and has good adaptability to low-frequency vibration, dust and other harsh environments.
Liyan Car DVR( IR CAR Camera supplier china ) has high anti-virus, due to the use of professional software and hardware, the data stored on the chip is read-only and cannot be written, and the software has very few incidental functions, and the virus has no way to invade.
To do a stable car DVR in addition to a stable operating system must also address the following issues:
The stable wide voltage, the voltage on the vehicle is unstable, and the fueling door, battery aging and other operations will affect the up and down fluctuation of the car voltage, the lowest possible up to 6V, up to 70V. Vehicle DVRs that do not have super wide voltages cannot work properly in cars. They often crash, do not record videos, and severely burn motherboards, power boards, video cameras, and even other equipment on the vehicles. Liyan Car DVR has done a lot of work on the power supply processing, the machine can work normally from 7V to 40V, with stable 12V/4A voltage output for camera and car display screen.
Professional anti-seismic treatment, the car mainly to low-frequency vibration-based, most of the car to 20HZ-40HZ vibration-based, poor anti-vibration treatment will cause the car DVR crash, restart, hard disk does not work, lost video segment and other issues. Liyan Car DVR has done a very professional treatment in the earthquake protection, mainly from two aspects: First, hardware, hard drive and the whole silicone shockproof silicone mat are their own open mold design, with low frequency vibration, the circuit board is used non-welding Plug wire, all wire connectors are locked. The second is software, independent research and development of car DVR( Vehicle Camera system supplier ) software with MPFS (Multiple Protection File System) file system and data high error correction.
Suitable for the structure of the machine on the car, bad environment on the car, heat dissipation, dust prevention, waterproof, anti-folding and anti-pressure are issues that must be considered. Car washing may cause water to enter other equipment in the car. Drivers, conductors, passengers, and other personnel will damage the machine's folding, filing, pressing, etc., the video recorder will generate a lot of heat, and a lot of dust will be generated on the car. These problems will affect The normal work of the car DVR, if any of these problems is not handled and resolved, will be a failed car DVR. Liyan Car DVR has designed a car DVR chassis according to the actual situation on the car. The chassis is made of strong steel plate. After the lock, there is no detachable silk thread on the outside. Before and after the use of blinds ventilation and heat dissipation waterproof; internal car DVR shell with aluminum profiles, The whole machine adopts a vortex vent to play the chimney pipe effect, and the aluminum plate on the main board is dustproof and heat-dissipating.
Convenient management, a large number of vehicles, each vehicle a large number of video data, if you can not do a quick and easy search and read, will cause the user to need a lot of people and time to manage. The video files of Liyan Car DVR are compatible with FAT32 format, and can be read directly on the computer through the hard disk reader. The file name of the video data is named with date, time and license plate number. The video data can be combined with license plate number, time, GPS information and Date, support CF card video and data copy.
