Asus is teasing by showing off a video that looks and sounds like a spy film trailer and with glimpses of a new Zenfone that has dual-camera configuration on the back. Asus posted #CES2015 and #Zenfone with the video, so we should get to see what the company has up its sleeve at the Las Vegas show in January.

Dual camera configurations found in smartphones so far give the camera extra depth for manipulating the background when editing. Asus says its dual-camera setup allows you to "see what others can't see".

HTC's One M8 also sports a dual camera on the back. What's left to see is whether Asus will differentate with the new models.

Asus launched a Zenfone line at CES last year, though it never really caught on in the U.S.
