Main Page → Properties pane → Properties: Camera
When a camera, or a camera group, is selected from the Devices pane, related camera settings will be displayed in the Properties pane.
From the Properties pane, you can configure the camera settings so that it is optimized for your capture application. You can enable/disable IR LEDs, change exposure length of the cameras, set the video mode, apply gain to the capture frames, and more. This page lists out properties of the cameras and what they are used for.
The Properties: Camera contains advanced settings that are hidden by default. Access these settings by going to the menu on the top-right corner of the pane and clicking Show Advanced and all of the settings, including the advanced settings, will be listed under the pane.
The list of advanced settings can also be customized to show only the settings that are needed specifically for your capture application. To do so, go the pane menu and click Edit Advanced, and uncheck the settings that you wish to be listed in the pane by default. One all desired settings are unchecked, click Done Editing to apply the customized configurations.
Basic information about the selected camera gets listed in the Details section
Prime color cameras also have the following properties that can be configured:
Default: 1920, 1080
This property sets the resolution of the images that are captured by selected cameras. Since the amount of data increases with higher resolution, depending on which resolution is selected, the maximum allowable frame rate will vary. Below is the maximum allowed frame rates for each respective resolution setting.
Default: Constant Bit Rate.
This property determines how much the captured images will be compressed. The Constant Bit-Rate mode is used by default and recommended because it is easier to control the data transfer rate and efficiently utilize the available network bandwidth.
Available only while using Constant Bit-rate Mode
Bit-rate setting determines the transmission rate outputted from the selected color camera. The value given under this setting is measured in percentage (100%) of the maximum data transmission speed, and each color camera can output up to ~100 MBps. In other words, the configured value will indirectly represent the transmission rate in Megabytes per second (MBps). At bit-rate setting of 100, the camera will capture the best quality image, however, it could overload the network if there is not enough bandwidth to handle the transmitted data.
Since the bit-rate controls the amount of data outputted from each color camera, this is one of the most important settings when properly configuring the system. If your system is experiencing 2D frame drops, it means one of the system requirements is not met; either network bandwidth, CPU processing, or RAM/disk memory. In such cases, you could decrease the bit-rate setting and reduce the amount of data output from the color cameras.
The image quality will increase at a higher bit-rate setting because it records a larger amount of data, but this will result in large file sizes and possible frame drops due to data bandwidth bottleneck. Often, the desired result is different depending on the capture application and what it is used for. The below graph illustrates how the image quality varies depending on the camera framerate and bit-rate settings.
Tip: Monitoring data output from each camera
Data output from the entire camera system can be monitored through the Status Panel. Output from individual cameras can be monitored from the 2D Camera Preview pane when the Camera Info is enabled under the visual aids () option.
Default : 24
Gamma correction is a non-linear amplification of the output image. The gamma setting will adjust the brightness of dark pixels, midtone pixels, and bright pixels differently, affecting both brightness and contrast of the image. Depending on the capture environment, especially with a dark background, you may need to adjust the gamma setting to get best quality images.
