We have had some issues with out-of-specs USB cables at the beginning of production. A corrective action has been enforced and said-cables have been replaced. Most cases of “bad” connections have been solved by changing the cables.
If you think that you may have old generation cables, check the recommendations for USB cables that we posted to check the gauge of the wire. You can also contact your distributor and check with him if a change of cables is possible.
We have obviously tested the cameras on many drones, commercial and customs.
I have to emphasize that securely tightening the cables close to the connector is the most important.
That and having the proper power supply.
