If you enable the Auto exposure option for an Arecont camera that is not a panoramic model, you can specify the auto exposure window size and position.


  1. From the Video task in Config Tool, select the camera to configure.
  2. Click the Hardware tab.
  3. Next to the Auto exposure setting, click Exposure window.
  4. To re-size the exposure window, do one of the following:
    • In the Size and position section, enter the X, Y, W, and H coordinates.

      X is the Top-left pixel, Y is the Bottom-left pixel, W is the Top-right pixel, and H is the Bottom-right pixel.

    • Drag the green zone to the size you want.
      NOTE: If you have a cropped field of view, then the exposure window must be contained within the cropped field of view.
  5. Click OK.
