Astra Stereo S capabilities

Hi there,
Just received the mail shot about the new models.
The Stereo S claims “support for outdoor and multi-camera applications”, but I can’t see how this is achieved from the tech specs.
The picture of the camera would appear to show stereo RGB lenses alongside the active IR array: so are passive stereo optics being used to enhance or compensate the IR depth field when the latter is impaired by sunlight or other IR projectors?
Grateful for any feedback: I’ve been waiting for an outdoor active IR to come along for years now.
