With the Open Advanced Settings button, you can set the features supported by your camera.
​
The camera block has 2 inputs, but you can take images without using these inputs. The functions of the inputs are as follows.
Activate Signal: In case of a true signal, it reads the picture data from the selected camera. Does not read when false signal is connected. If no connection is made, the block automatically runs in continuous reading mode.
Release Signal: In multi-camera applications, your device may not receive images from more than one camera at the same time. For this reason, you may need to deactivate some of your cameras from time to time. As long as this socket receives the True signal, it closes its access to the selected camera. If this socket is connected and False signal is coming , the selected camera is accessible . If no connection is made, the camera is always ready to transfer images.
