Optics and Object Distances for Analytics – Rhombus Systems

Different Rhombus cameras can identify objects (like people, faces, license plates) at varying distances.

Below is a table that summarizes the distances (in feet) that our various cameras can detect these objects at. The facial and license plate recognition row is meant to highlight the max distance the particular camera model can perform our automatic license plate and facial recognition. A human looking at the video will likely be able to identify these items at distances a little further.
