What is 4 Channel Mobile DVR?

A 4-channel mobile DVR is a device used for vehicle monitoring. It can simultaneously connect and record video data from four cameras and store the data in a hard drive or SD card.

A 4-channel mobile DVR has multiple camera input interfaces that can be installed in different positions on the vehicle such as the front, rear, interior, and surroundings. Each channel can independently record video, making the monitoring more comprehensive. This device is commonly used in commercial vehicles, buses, taxis, and other vehicles that require monitoring multiple directions simultaneously.

In addition to multi-channel recording, a 4-channel mobile DVR typically has functions such as loop recording, emergency event-triggered recording, GPS tracking, G-sensor vibration sensor, etc., to provide more comprehensive vehicle monitoring and management.

In summary, a 4-channel mobile DVR is a device suitable for vehicles that require monitoring multiple directions simultaneously, which can provide comprehensive video monitoring and help drivers and fleet managers better manage fleets and enhance safety performance.
