Vehicle Blackbox DVR Camera System

What is a Vehicle DVR System

A vehicle DVR camera system, commonly known as a dash cam, is a dedicated embedded device for automobiles, essentially serving as the vehicle's "black box".

It can continuously record video footage inside and outside the vehicle while the vehicle is in motion or parked, fully capturing road conditions and the surrounding environment.

Functions of the Vehicle DVR Camera System

The core function of a vehicle DVR is video recording, and modern systems are equipped with more comprehensive features:

①　Loop Recording: Performs continuous recording when powered on. When the memory card is full, it automatically overwrites the oldest files, eliminating the need for manual management.

②　Event Recording (G-Sensor): Built-in G-Sensor detects impacts, sudden deceleration or acceleration, and locks the corresponding video files to prevent overwriting.

③　Parking Mode Recording: Switches to low-power mode after the vehicle is turned off. It wakes up to record when movement or impact is detected, requiring a hardwired connection to the vehicle battery (with voltage protection).

④　Audio Recording: Equipped with a built-in microphone to record in-vehicle or ambient sound, which can be disabled by users for privacy reasons.

⑤　Data Storage: Video footage is stored on a microSD card, HDD/SSD or cloud server, with the maximum supported capacity varying by device.

⑥　GPS Logging: High-end models are equipped with GPS, embedding location and speed data into video, which can be viewed synchronously using dedicated software.

⑦　Wireless Connectivity: Some models support 4G connectivity, allowing connection to mobile phones via an APP for real-time viewing, playback, video downloading and setting adjustment.

Ordinary Dash Cam vs. Professional Mobile Digital Video Recorder (MDVR) for Vehicles

The use of consumer-grade dash cams in commercial vehicles is prone to video loss, hardware damage and legal risks. The key differences between the two are as follows:

Components of the Vehicle DVR Camera System

A complete system requires the integration of four major hardware components to ensure data integrity and all-round visibility:

①　Vehicle Mobile DVR Unit (MDVR): The core of the system, responsible for processing video signals, encoding and storing footage.

②　Industrial-grade Cameras: Support 4-8 channels, and can be connected to dedicated cameras for side view, rear view, driver monitoring and other purposes.

③　Aviation Cables: 4-pin aviation connectors, securely locked to ensure stable signal transmission.

④　Operator Display: Dashboard-mounted screen, providing real-time views of blind spots and reversing scenarios.
