How to access R1 binocular depth camera / depth stream?

Hello,
The R1 Basic/EDU documentation mentions a binocular depth camera with approximately 150° horizontal FOV, depth output at 544×448 @ 10 Hz and RGB at 1280×1088 @ 30 Hz.

However, on our R1 we can currently access only a single monocular H.264 RTSP stream at 192.168.123.161:8551.

We cannot find a stereo pair or depth stream.

Could you please clarify:

  1. Does our R1 have the binocular depth camera installed?
  2. If yes, how can we access the depth data?
  3. Is there a specific IP address, RTSP stream, DDS topic, SDK interface or service for the depth camera?
  4. Is any additional software or driver required?
