- In the System Resources tree, select the relevant node and in the Properties pane, view the current settings.
If the FLIR camera isn't displayed in the System Resources tree, or if it's displayed with a yellow warning triangle, or if you haven't already set the system frame rate, see Set up the software for a FLIR Blackfly S system in the FLIR Video Cameras Setup Guide.Scroll pagebreak

The camera performs better when it is providing data in its native pixel format. This is a Bayer format, such as BayerRG8.
No bandwidth is saved by selecting Luminance8. B8G8R8 and B8G8R8u8 use three and four times as much bandwidth, so are not generally recommended.

- The frame rate of the Vicon system (see Set the system frame rate in the FLIR Video Cameras Setup Guide). The video rate must exactly divide into the system rate.
- The limits of the camera/sensor. These are fixed and cannot be changed.
- The current pixel format of the camera.
- The Area of Interest (window) set on the camera.
Usually it is desirable for the system rate to be the same as or higher than the video frame rate. For example, if the system frame rate is 120 Hz, the permitted video frame rates will include 30 Hz, 60 Hz and 120 Hz.

Ensure you set the video image parameters appropriately.
- Shutter duration The shutter duration time is given in microseconds. The exposure is limited to the length of the frame period. If it is set too high, the camera might not be ready for the next frame before the trigger is received and the software inserts black frames to maintain synchronization. This is usually undesirable behavior, so to avoid this, decrease the exposure slightly until the warning disappears.
- Camera Gain If the image is too dark, adjust the gain to compensate. Avoid using too much gain when a longer exposure time or better lighting is needed instead. Excessively high gain results in a noisy image.
- Black Level This property controls how dark the darkest areas of the image appear. Adjust this as desired.
- SaturationThe gamma property affects the actual data sent from the camera, not just the display. It is only enabled when the camera converts from its native pixel format to 24-bit or 32-bit RGB. It is disabled when using the camera's native Bayer format. By default the camera uses the Bayer format, so this option is disabled by default.
- Auto White Balance This property uses an algorithm on the camera to improve the appearance of color in the image. If you require more predictable color, you can disable it and set the green/red and green/blue balance manually.
- Green/Red Balance When auto white balance is disabled, allows the green/red balance to be adjusted.
- Green/Blue Balance When auto white balance is disabled, allows the green/blue balance to be adjusted.
- Camera Gamma The gamma property affects the gamma level of the actual data sent from the camera, not just the display.

There are two supported ways of reducing the image size: setting an area of interest (AOI) or enabling binning.
