Driver Monitoring System (DMS)
Using DMS technology, the JC400D can assess the driver's alertness behind wheels and warn the driver with in-cab alerts if any sign of drowsiness or fatigue or inattentiveness is detected.

Driving Behavior Monitoring
Leveraging data on the driving behavior of your drivers, including harsh acceleration, harsh braking, and sharp turn will help reduce accident rate and improve fuel economy of your fleet.
  • Harsh Acceleration
  • Hard Braking
  • Sharp Turn
Event Video to Cloud
Event Video to Cloud
In the event of a serious accident, collision or improper driving behavior, the JC400D will, as required, capture event videos and send them to the cloud for storage. With a 4G connection, you can have faster data speeds and wider network coverage, enabling you to respond or take action immediately.
Panic Button
In the event of an accident or other emergency, one-press of the panic SOS will trigger the device to help the driver or passenger initiate an emergency call to pre-set SOS numbers and the back office until the call is answered and to flag important video footage for review. The external SOS button can be installed within easy reach of the driver or passenger for quick activation, giving peace of mind to all.

Engine Cut-Off
Long-distance truck, van, and taxi drivers are prone to fatigue because of long hours behind the wheel. It is of paramount importance for you to be able to immobilize a vehicle in your fleet if you find the driver has exceeded their HOS. Besides, you never know if your vehicle is safe from theft or un-authorized use, so the remote engine off capability of the JC400D can be proved to be useful in a way or another.

Real-time video problem
After customers get the equipment, some devices have been unable to achieve real-time video function

Problem analysis

- It is suspected that the RTMP server logged on by the device has a problem, resulting in the device logged on to this server cannot perform real-time video.

- The function may return to normal after a period of time, but the possibility of a recurrence is not ruled out.


The Solution

- In this case, it is necessary to give immediate feedback to the FAE, so that the r&d team can troubleshoot server problems as soon as possible and find the root cause to avoid causing major problems.

- It is necessary to provide the LOG file of one device in the country or region where the device is located for the convenience of research and analysis.

All the devices under the customer account suddenly cannot provide real-time video, and the customers receiving feedback are all in the same or adjacent areas
