Each time I use depth viewer, under the left camera will have a blue light. Is that true for zed 2i camera using two camera for stereo matching? Is the blue light a depth sensing camera?
Is there any details about the depth sensing principle?

Hi @dians
the blue led only indicates that the camera is operating, it’s not used by the Depth processing algorithm.
You can turn it on and off by using ZED SDK API commands:
C++/Python
