Here's my setup. From top to bottom:
CCD-600 (Not Visible)
...
CCD-1000
My Search-engine-fu failed me. "CCD" commonly stands for "Charge Coupled Device". Adding "bitcoin -camera" to the search terms brought up Sony console game .torrents (apparently .ccd is a common extension).
A search of this forum for "CCD-600" only brought up the above post.
My apologies. CCD-600 appears on the invoice for the bitmine.ch CoinCraft Desk 600GH.
