Biases pre-sets

Prophesee Event-Based sensors can be tuned for optimal functioning in a specific applications and in a particular environment condition by adjusting the sensor settings so-called biases.

On this page we provide several biases pre-sets for different applications. These pre-sets should be seen as a starting point for bias tuning for a particular application and not as a final solution. The final solution will depend on many factors and here we provide only a generic idea.
