School bus safety issues has become the public hot topic in recent years, school bus as  transport vehicles to go to and back from school for a child every day, its security can not be ignored. In addition, students tend to make man-made causes of injury in the school bus, this leads to liability disputes between schools and parents; the mobile 4G remote vehicle monitoring system helps to solve these problems by installing the camera and video system in the school bus, All situation like students get on/off the bus, and the entire process of school bus running are recorded every moment. Through wireless monitoring system, parents or administrators can also track  real-time situation of the school bus anywhere and anytime by the Internet or mobile phone.

Device Control

Support PTZ control, remotely turn off the oil function, LED electronic screen control etc external devices’ control functions.

WIFI automatic download function

1, WIFI automatic video download

System support when the vehicle enters into the WIFI area, video download software will automatically download device-side video in accordance with the task scheduler and store them on the local computer configured on a good hard disk partition. Support download per day per time types.

2, WIFI download priority

Support 4G and WIFI online at the same time , when the vehicle enters WIFI area,

1), Communications link channel is 4G;

2), Video preview and download is completed via WIFI.



Power protection (patented approved)

The device using UPS patented technology enables the device to work 3-5 seconds when the external power cut off supply:

1), Ensure video data saved integrity, avoid file corruption, ensure video files completed. Especially when unexpected event occurs it ensures valuable data is recorded at burst moment!

2), when the vehicle power supply is lower than voltage 6V or less instantaneously , the device does not power down and restart, ensuring the integrity of the video, but also reduces the small fragments of video files

Damping design

Vehicle monitoring terminal applied in bumps, vibration, swing and other harsh environment, to ensure the equipment long-term stability, we have to put forward a higher requirement, especially for storage media isolation technology is the focus of the system problems. Thus, the device uses a professional hard drive vibration isolation technology and industrial grade SD card, Car MDVR easily damaged hard disk, SD card connector loosening has been solved.

Wide temperature design

The system equipment operating temperature:

Hard disk drive: -25 ℃ ~ + 60 ; when it is low temperature, the device can automatically heart hard disk to a working state.

SD card: -25 ℃ ~ + 70 

Flexible way to record video

support reboot video recording, alarm recording, schedule recording, remote start  recording and other multiple video mode.

Hard disk drive: The hard drive using an optional SD card mode, dual stream simultaneous recording and the hard disk abnormal recording(optional), ensure that even if the hard disk is not working, SD card is still recording all state vehicles via slightly lower stream.

SD Card: This system supports SD card looped coverage recording, it solves SD card smaller capacity problem, the system device supports a single 64G SD card capacity.

G-sensor function

This vehicle mobile terminal supports G-sensor function, the state (braking, sharp turns etc.) of vehicle operation were recorded and stored in the video file. It is ok to analyze the running status of vehicles by the playback software operation graph of the vehicles.
