  • In Oak D Lite fixed vs auto focus for surveillance camera?

    Oh and as another datapoint @rlaferla - as long as your camera will be at least 1.5 feet from what it's looking at, fixed-focus will be fine.

    Almost all security cameras are fixed focus for this reason. As then there's no risk of auto-focus hunting because of bugs close to the camera/etc.

    • In Oak D lLite resolution and bandwidth

      Hi @rlaferla,
      you can downscale the 4K stream using the Image Signal Processor (ISP) the following way:

      camRgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_4_K) # 3840 x 2160
camRgb.setIspScale(1, 3) # 1280 x 720

      For more information about the setIspScale method, see the documentation here.
      Is this what you meant by "down converting" the 4K stream"?
