Troubleshooting – Arducam ToF Camera

Notice

Thank you for trying our latest product, the Time of Flight (ToF) camera.

Arducam puts quality first as this is how we deliver added value to you, users. Apart from the solid implementation of Total Quality Management (TQM) and carrying out ISO 9001 throughout the whole producing process both in-house and compliant subcontracting, every single camera has to pass the inline and final inspection before getting a qualification release.

Failure to successfully use a camera, however, still might happen. Besides possible product defects, there are many other influential factors, including but not limited to transportation damage, negative environmental conditions, improper ways of use, etc.

Tips

If your Arducam ToF camera does not work as described, it is highly recommended, for a very likely obtained time-saving, that you go through this checklist before reaching out to our support team.

  • Before connecting, you should always power your Raspberry Pi or NVIDIA Jetson off and remove the power supply first.
  • Make sure a recommended OS version is used for your Raspberry Pi or NVIDIA Jetson. (Pls refer to their respective docs)
  • Make sure the cable on the camera board is locked in place.
  • Make sure the cable is correctly inserted in the connector.
  • Avoid high temperatures.
  • Avoid water, moisture, or conductive surfaces while in operation.
  • Avoid folding, or straining the flex cable.
  • Avoid cross-threading with tripods.
  • Gently push/pull the connector to avoid damaging the printed circuit board.
  • Avoid moving or handling the printed circuit board excessively while it’s in operation.
  • Handle by the edges to avoid damage from electrostatic discharge.
  • Where the camera board is stored should be cool and as dry as possible.
  • Sudden temperature/humidity changes may cause dampness in the lens and affect the image/video quality.
