How to Adjust TennaCAM 2.0 Fleet Alignment for Seatbelt Detection
In order for the TennaCAM 2.0 Fleet to properly detect a driver’s seatbelt being used, the camera’s Channel 2 (cabin facing camera) must be aligned correctly. Follow the directions below to ensure seatbelt events are captured properly.
Driver Positioning in the Video Frame
The driver should be positioned towards the right-side of the video frame with their face and shoulders centered vertically in frame as close as possible.
As depicted in the image above, the driver's face should be vertically centered and towards the top half of this box for best performance, but most importantly for accurate seatbelt detection is that the driver's shoulders are within this box.
Below are two examples of improper alignment.
How to Adjust the Camera Angle
- 1
- Start the vehicle's ignition and allow the camera to boot up.
- 2
- Login to your Tenna account.
- 3
- In Assets, search for your vehicle.
- 4
- The vehicle should show up as live and online. Select the television icon to open the camera feed.
- 5
- In the Map View, select the drop-down to select Channel 2.
- 6
- While sitting in the front seat, adjust the camera angle to ensure the view of the driver meets the recommendations described above.
Use a T20 Torx wrench to loosen the center mounting bolt on the camera to rough adjust the angle and ensure the camera is level.
Then, if necessary, use a T8 Torx wrench to fine adjust the camera lens up or down.
- 7
- Once the angle is adjusted, tighten the mounting bolt so that the camera does not move.
