What looks like a camera under the rearview mirror of Volvo XC90? Is it a camera? If so, what is it used for?

The camera of the blind spot information system keeps taking pictures when the vehicle is driving, and then sends these photos to the BLIS computer module, which compares these photos to analyze whether there are moving objects or people behind the vehicle. If there is, it will light up at the position of two mirrors in the cab.
