 - **Time-to-Host** is measured time between frame timestamp (:code:`imgFrame.getTimestamp()`) and host timestamp when the frame is received (:code:`dai.Clock.now()`).
 - **Histogram** shows how much Time-to-Host varies frame to frame. Y axis represents number of frame that occurred at that time while the X axis represents microseconds.
 - **Bandwidth** is calculated bandwidth required to stream specified frames at specified FPS.
