Orbbec Persee depth images only streaming when objects up close

I working with the Persee, trying to get a continuous depth stream via opencv and OpenNI2 (working in Ubuntu 16.04). I am getting weird behaviour where the frame rate of the depth stream seems to be effected by the proximity of objects being imaged in the depth frames. When I bring an object up close, and moving, a burst of frames is observed. Away from the sensor, the frame rate either drops to only a few, or in some cases, hangs completely and only recommences when an object is brought close. I want a continuous regular depth image video stream, and cannot work out what is going on. Any help greatly appreciated.

I have the same problem on an Astra S camera. Any solutions or why is that?
