PlayStation Camera sales stand at around 900,000 units, a Sony engineer claimed during a Game Developers Conference session this week.
During a talk entitled 'Creating Unique Interactive Experiences with PS4', which was attended by GameSpot, PlayStation US senior staff developer support engineer Chris Norden said the PS4 peripheral has an attach rate of about 15 per cent.
PS Camera acts as a webcam for those using the console's live broadcasting features, as well as a motion-detecting gameplay device for augmented reality experiences such the pre-installed mini game The PlayRoom.
Norden reportedly said that Sony underestimated demand for the peripheral. It is currently "severely supply constrained" so "please be patient", he's quoted as saying.
In early March, US retailer GameStop increased the PS Camera price by $10, from its $59.99 MSRP to $69.99. A Sony spokesperson said at the time. "While we do not comment on the sales figures, shipment or monthly production quantity, PlayStation Camera remains in high demand."
Sony claims that worldwide PS4 sales totalled six million units as of March 2. The console launched in North America on November 15, 2013, in Europe two weeks later, and in Sony's home nation on February 22. It is currently available in 57 countries worldwide.
