title: Get the serial number of a camera - Openni2 python
body: <p>I'm using python3 and openni2.</p>
  
  <p>When I open the communication with a camera (in this case I'm using an Orbbec Astra), is it possible to read the serial number of the camera?</p>
  
  <p>This is how I open the communication:</p>
  
  <pre><code>    dev = openni2.Device.open_any()
      depth_stream = dev.create_depth_stream()
      depth_stream.start()
      depth_stream.set_video_mode(c_api.OniVideoMode(pixelFormat = c_api.OniPixelFormat.ONI_PIXEL_FORMAT_DEPTH_100_UM, resolutionX = 320, resolutionY = 240, fps = 30))
  </code></pre>
  
  <p>My goal is to find everytime the same camera even if I change the usb port and I've more orrbec connected.</p>
  
  <p>Thank you</p>
