Is there a way to use the rear facing camera on devices not front?

Just worked it out: In CameraStreamer.js

this._constraints = { audio: false, video: { width: width, height: height, deviceId: { environment: undefined }, facingMode: "environment" } };

I edited the js file as mentioned above starting at line 41, but it still uses my phone's front camera.

Is there anything else that I need to change to take the first available rear camera?
