Article difficult to find in major retailers (especially substituted STC4000 STC5000: created for newer televisions).

Strangely (but this does not hinder) the person watching me see that the camera does, occasionally, zoom to where I am pretending to be concentrating on my face or cover the entire room. Yet I do not move and the camera is not mobile.Sans consequences
