Configuring the Camera

16 Basler IP Camera

3.4.1 Global Tab

The parameters on the Global tab control the way that the camera’s imaging sensor will capture

images. Because the images captured by the sensor are used for all three video streams, the

parameters on this tab are considered to be "global", i.e., changes made here will affect what you

can do when you work with the individual stream parameters.

Some of the parameters in this group are used to set the imaging sensor’s "area of interest" (AOI).

The sensor AOI settings let you define the area on the sensor that will actually be used when the

camera is capturing images. You can set the AOI settings so that the full sensor is used to capture

images or so that just a portion of the sensor is used as shown in Figure 3.

The sensor AOIWidth and sensor AOI Height parameters define the width and height (in pixels) of

the image area that will be captured. The sensor AOITop and sensor AOILeft parameters define

where the image area will be located in relation to the top left corner of the sensor.

Why Decrease the Sensor AOI Size?

On some camera models, typically those with large imaging sensors, the maximum rate at which

the sensor can capture images (i.e., the frame rate) is limited. On these cameras, when you

decrease the height of the sensor AOI, the rate at which the sensor can capture images will

increase. So if you need to capture images at a higher rate, decreasing the size of the sensor AOI

may be a workable option that will allow you to do so.
