At first glance, the Surface Pro 4 appears to outshine its predecessors with its forward sensor array.

We spy at least four nodes of interest. One's a camera, one's probably a microphone, but the rest?

On the rear of the new Surface, we find a familiar arrangement of circles—the 8 MP rear-facing camera accompanied by a status LED and microphone.

Anxious to see the camera array but too impatient to open the device? X-ray it.
