How to use Mayika KA-501A to set driver fatigue alarms and how to install a camera with the KA-501A?


We are clearly in the age of innovation, as the automobile sector designs for a safer world with electric cars (EVs), autonomous systems, and other advances in digitisation. In this post, we'll go over how to use a feature in Mayika called driver fatigue detection to prevent accidents.

Driver fatigue signals come in a variety of forms and are commonly seen in mobile video digital recording systems, or MDVRs. It's worth noting that these notifications are part of the Driver Monitoring System (DMS), which uses driver-facing cameras rather than the road-facing cameras in other advanced driver assistance systems (ADAS). Continue reading to learn more about mayika's detection technologies, setting up alerts on your platform, and camera installation.

What is driver fatigue?

Simply put, driver fatigue is a brief time of unconsciousness that occurs even when your eyes are open. It is critical for safe travel to provide drivers with an early warning when they need to take a break behind the wheel.

The technology behind fatigue detection systems

Fatigue detection systems use sensors to monitor the driver and their driving style in order to limit the risks of fatigue causing an accident. When fatigue is identified, the driver receives reminders or "alerts" to take a rest. These systems may also be combined with adaptive cruise control and other autonomous driving technologies, allowing them to deactivate immediately if the car detects that the driver is not paying attention. There are two types of systems for detecting fatigue. There are cameras that track drivers' facial movements, as well as indirect systems that use front-facing cameras to monitor vehicle movement.

The second form of system tracks the driver's facial movements, like head motions and blink rates, using one or more cameras facing them. Other motions that can be tracked include:

Steering pattern monitoring: This tracks and analyses the "proper" steering cues and patterns to follow, which can be customized.

When a driver veers off-centre, the vehicle position in lane monitoring informs the driver or even locks the wheel.

Other intelligent algorithms: Some systems may go so far as to alert users when their breathing patterns change to those of a sleeping person, giving them a heads-up before they become drowsy.

You'll need to develop a special rule within the Mayika platform to take advantage of these features. Here's how to make a new Mayika driver fatigue rule:

  • Select "alerts" from your control panel.
  • For "Event Type," select "Add rule" on the right side of your screen.
  • Look for the word "safety."
  • Select "Driving Fatigue" from the "Safety" menu.
  • Create a rule and choose a notification type.
  • Create a rule and choose a notification type.

KA-501A in Action: Preventing Accidents

This facial recognition technology evaluates gestures in humans that suggest exhaustion, such as closing eyes, yawning, looking away, or distractions such as phones. It generates loud alerts to wake up or warn the driver of their behaviour when it detects the events, in addition to sending messages to the monitoring centre.

This type of camera is a solution for accident prevention because fatigue might cause a driver to fail to respond in time to avoid a road hazard. Drowsy drivers have been shown to change lanes more frequently, have difficulty controlling their speed (changing between low and high speeds), and have difficulty maintaining the right distance from other vehicles. A huge percentage of fatigue accidents involve a driver speeding off the road or into another lane.


In this situation, the KA-501 tracker is compatible with the KA-501A fatigue camera. This camera also includes an internal GPS antenna for speed detection. Additionally, up to five drivers' faces can be registered so that they can be recognised as soon as the ignition is turned on. The most essential feature is that this camera can transmit alerts to fleet managers and generate reports of detected events via its RS232 connection output, which is integrated into the Mayika Platform.

These dash-cams also allow live streaming video and features an SD card slot for storing video recordings based on warnings. The camera can record up to 80 hours of video at a resolution of 480x720 pixels and takes SD cards up to 128 GB. It can also be connected to inform the driver in real-time and prevent accidents, thanks to its connection to the ADAS system.

The following are the alerts and events that this fatigue camera detects:

  • Connection to the cameras
  • Drowsiness starts
  • End of drowsiness
  • End of distraction
  • Yawn
  • Start using the phone.
  • The use of the phone has come to an end.
  • Begin to smoke
  • Give up smoking.
  • Absence of a driver
  • Return
  • Introducing the New Driver
  • Detection of Driver ID
  • Begin recording
  • Disconnecting the camera

The following is a step-by-step installation procedure:

  • Ensure that the face is in the centre of the box.
  • Set up yawns, tiredness, distraction, and smoking.
  • For each event, change the volume of the alarm.
  • If you have accessories, you'll need to configure their notifications as well.
  • Set the level of sensitivity for the occurrences.
  • The ignition must be turned on before the camera can be spotted.
  • Keep in mind that the connection is made via the RC232 serial port and requires a voltage range of 12-36 volts. Furthermore, the yellow-currant and red-ignition connection wires must be put in the following order: yellow-currant and red-ignition.
  • Placing the fatigue chamber in front of the driver is the next step.
  • The distance between the conductor and the centre must be between 90 and 100 cm.
  • If you can't put it in the middle, you can tilt it up to 15 degrees to the left or right.
  • Make sure it's slightly lower than the driver's eye level, about 10° to 20°.
  • 4 screws are used to secure the camera to the board.

Connect your Suntech device to Mayika, and you can start configuring the alerts you'll receive from the fatigue camera in the new alerts module, thanks to the newest update and integration enhancements with this tracker.

Driver fatigue alarms can save lives in any business or situation. If you'd like to try out these features on your own and see how they work, we invite you to try out a Mayika platform demo.
