TennaCAM 2.0 Fleet Driver-Facing AI (DMS) Overview and FAQ
Overview of TennaCAM 2.0 Fleet driver-facing safety events (drowsiness, distractions, head down, phone use, seatbelt, smoking, yawning), specifications for those events, and FAQ.
TennaCAM 2.0 Fleet uses an Artificial Intelligence (AI) based Driver Monitoring System (DMS) to detect specific driver actions and to generate events and in-cabin voice alerts. Voice alerts notify the driver of the detected condition. A video clip may be automatically captured by the camera for each of these events.
Benefits of AI-powered Safety Cameras
Increased Safety
- Videos and alerts allow fleet managers to coach drivers, mitigate risky habits, and constructively teach better driving skills.
- Videos provide context for telematics-based driver scorecards. For example, a point deduction for harsh braking could be a driver avoiding an obstacle or other danger.
- Videos help identify, retain, and reward excellent drivers.
Accident and Liability Mitigation
- Instantly provide video evidence of accidents to law enforcement and insurance.
- Exonerate drivers who are not at fault for accidents or complaints from other drivers.
- Speed up resolution of insurance claims.
- Settle or avoid expensive lawsuits.
- Deter theft/vandalism with parking mode

FAQ
Can I customize the settings for each event?
Settings for each event type include turning on/off video or snapshot, enabling/disabling in-cabin alerts, sensitivity levels. These settings are pre-configured based on your current camera settings profile. Tenna also offers a Custom Settings profile for those that would like more control.
How does the camera detect if the driver is wearing their seatbelt or not?
To get the best performance from the camera for seatbelt detection, the camera must have an optimal view of both the driver's face and shoulders area. If the camera is positioned poorly, it may cause the camera to miss the seatbelt being worn and generate false positives or to not generate any events when these may be expected.
Refer to How to Calibrate TennaCAM 2.0 Fleet for Seatbelt Detection for more information.
How do I prevent false positives for seatbelt detection?
The best way to prevent false positives is to calibrate your camera’s angle to match these instructions. The following are other things that can contribute to false positives:
- Poor driver posture
- If the driver positioned in a way that covers the seatbelt (for example, hunched over or driving one handed with their right arm covering their left shoulder).
- Recommendation: Encourage your drivers to always drive safely with both hands on the wheel. Ensure that the driver is not mistakenly blocking the camera's view of the seatbelt.
- Glare or poor lighting in the cab
- Glares from sunlight or roadway lights can reflect onto the driver, making it hard for the camera to detect a seatbelt.
- Poor contrast between the seatbelt and driver’s clothing
- If the driver is wearing a shirt that blends with the color of the seatbelt, false positives may present.
Tenna is committed to continuing to improve camera ai capabilities, as safety is our top priority for you and your team members. In the event of constant false positives, please forward to your Tenna Rep for review.
