What is car MDVR？

Mobile Digital Video Recorders (MDVR), commonly known as in car DVRs or in car hard disk recorders, are devices that use advanced video and audio encoding and decoding technology to convert and compress videos from inside and outside the car. It also integrates additional functions such as GPS positioning, in car entertainment playback, wireless network transmission, and is a type of automotive electronic device.

The main functions of in car MDVR include supporting multi-channel real-time image and audio recording, OSD overlay of video files (which can overlay information such as time, license plate number, speed, etc.), pre recording before alarm and delayed recording after alarm. In addition, it also has powerful mobile network functions, built-in communication modules, and can upload real-time images, alarm information, and GPS information to the central monitoring platform. At the same time, it also supports a wireless LAN communication module, which can preview images in real-time and automatically download video files through the wireless LAN.

Vehicle mounted MDVR combines advanced technologies such as digital video and audio encoding and decoding, environmental protection, large capacity data storage hard drives, automotive electronics, wireless video network transmission, GPS satellite positioning, etc., to achieve video and audio monitoring in the passenger transportation industry, special vehicle industry, and other related fields. In the vehicle remote monitoring system, the vehicle mounted MDVR is an important component, which together with the vehicle mounted camera, various sensors, monitoring platform, and network transmission equipment, forms a complete system.

How to record and save videos in car mounted MDVR？

Power on and preparation: Connect the charger and the MDVR will automatically turn on. Please make sure to insert an SD card or SSD before use, as video files will be stored on the SD card.

Recording video: After MDVR is turned on, it will automatically enter video mode, and the video indicator light will flash to indicate that it is recording. If you need to stop recording, just press the OK button.

Preview and selection: In preview mode, you can enter preview mode by pressing the mode key and use the up and down keys to select the video file you want to view. Press the OK key to play or pause the video, and press the Mode key to exit the preview mode.

Save Video: The recorded video file will be automatically saved to the SD card without the need for manual operation. You can export or backup video files from the SD card by connecting to a computer or other storage device.

In addition, in car MDVR usually has some other functions, such as screen display switching (can switch between front lens display, rear lens display, and 4-channel simultaneous display), screen saver (short press the power button to turn on or off the screen saver function during standby or recording), and infrared night vision function (can record clear videos at night or in low light environments). lViverra aliquet eget sit amet.

Mobile Digital Video Recorders with Solid State Drive (MDVR) is a type of in car digital video recorder that uses a solid state drive (SSD) as the storage medium

Compared with traditional in car DVRs that use mechanical hard drives, in car SSD MDVR has higher seismic resistance, lower power consumption, and faster read and write speeds. This is because SSDs do not have mechanical components, so they are not affected by vibration and impact, and can provide more stable and reliable video recording in the vehicle environment.

In addition, the in car SSD MDVR also has other additional functions, such as GPS positioning, in car entertainment playback, wireless network transmission, and so on. These features make in car SSD MDVR widely used in various mobile video surveillance fields such as buses, subways, trains, long-distance buses, taxis, logistics vehicles, private cars, and special vehicles (such as cash carriers).

Overall, in vehicle SSD MDVR is an electronic device that integrates high-performance video encoding and decoding technology, solid-state drive storage technology, and various additional functions, providing important support for vehicle monitoring and management.

Comparison of SD and SSD in Vehicle MDVR:

Firstly, it should be clarified that SD actually refers to an SD card, which is a type of flash memory card, while SSD stands for solid-state drive. There are significant differences in performance, durability, and application scenarios between these two storage media.

For SD cards, they are typically used to store small amounts of data, such as photos, music, or video clips. The speed of SD cards is relatively slow, especially when writing large amounts of data, their performance may be limited. In addition, the seismic resistance of SD cards is relatively weak, and if encountering bumps or impacts during vehicle driving, it may lead to data loss or damage.

SSD solid-state drives are completely different. It uses flash memory particles as storage media, with faster read and write speeds and higher seismic resistance. This means that using SSDs in on-board MDVR can ensure fast writing and reading of video data, while also maintaining data integrity and security during vehicle operation. In addition, SSDs have lower power consumption and longer lifespan, making them an ideal storage medium for in vehicle MDVR.

Specifically, in car SSD MDVR has the following advantages compared to in car MDVR using SD cards:

Higher read and write speed: The read and write speed of SSD is much faster than that of SD card, which can ensure that the in car MDVR has higher smoothness and real-time performance when recording and replaying videos.

Better seismic resistance: SSDs have no mechanical components, so they are not affected by vibration and impact, and can maintain data integrity and safety during vehicle operation.

Longer lifespan: SSDs have a longer lifespan than SD cards, ensuring stable performance of in vehicle MDVR during long-term use.

Larger storage capacity: SSDs typically have a larger storage capacity than SD cards and can store more video data.

In summary, in car SSD MDVR has higher performance, better durability, and larger storage capacity compared to in car MDVR using SD cards, making it more suitable for applications such as in car monitoring and recording.
