Camera on back of rear view mirror

[aggie]

On the back of the rear view mirror on my 18 reg 1.4 Xcellence there is what looks like a camera or some sort of aperture. Can anybody give me a clue as to what's it's for?

Cheers mate I was hoping it was the camera for traffic sign recognition but obviously not. Thanks for the answering my query.
