The social media giant have internally named the device Ripley and the high-tech piece of equipment is to use AI (Artificial Intelligence) to detect user's movement during video calls, according to the tech news outlet Cheddar.
However, Facebook are yet to comment on the reports.
The idea comes after the app launched a pair of Alexa-powered video chat devices for the home, called Facebook Portal and Facebook Portal Plus.
The device features a 10 inch, 1280 x 800 display (in landscape) and is available for pre-order in the US for $199 (£150). The Portal Plus, meanwhile, features a 15 inch, 1920 x 1080 pivoting display (in portrait), and is up for pre-order for $349 (£270).
Addressing the issue of privacy and how they device works, Facebook said in a blog post: "We know that privacy and security are important when you bring new technology into your home.
"That's why we designed Portal with tools that give you control.
"To manage Portal access within your home, you can set a four- to 12-digit passcode to keep the screen locked. Changing the passcode requires your Facebook password.
"We also want to be up front about what information Portal collects, help people understand how Facebook will use that information, and explain the steps we take to keep it private and secure.
"Facebook doesn't listen to, view, or keep the contents of your Portal video calls. Your Portal conversations stay between you and the people you're calling. In addition, video calls on Portal are encrypted, so your calls are always secure.
"For added security, Smart Camera and Smart Sound use AI technology that runs locally on Portal, not on Facebook servers. Portal's camera doesn't use facial recognition and doesn't identify who you are.
"Like other voice-enabled devices, Portal only sends voice commands to Facebook servers after you say, 'Hey Portal'".
