New Samsung TVs Have Built-In HD Camera, Microphones, Face and Speech Recognition
Here’s a bit of context that most people won’t consider when purchasing these quasi telescreens ~ Video
More and more personal and household devices are connecting to the internet, from your television to your car navigation systems to your light switches. CIA Director David Petraeus cannot wait to spy on you through them.
Samsung’s 2012 top-of-the-line plasmas and LED HDTVs offer new features never before available within a television including a built-in, internally wired HD camera, twin microphones, face tracking and speech recognition. While these features give you unprecedented control over an HDTV, the devices themselves, more similar than ever to a personal computer, may allow hackers or even Samsung to see and hear you and your family, and collect extremely personal data.
While Web cameras and Internet connectivity are not new to HDTVs, their complete integration is, and it’s the always connected camera and microphones, combined with the option of third-party apps (not to mention Samsung’s own software) gives us cause for concern regarding the privacy of TV buyers and their friends and families.
Samsung demoed these features to the press earlier this month. The camera and microphones are built into the top if the screen bezel in the 2012 8000-series plasmas and are permanently attached to the top of the 7500- and 8000ES-series LED TVs.
A Samsung representative showed how, once set up and connected to the Internet, these models will automatically talk to the Samsung cloud and enable viewers to use new and exciting apps.
These Samsung TVs locate and make note of registered viewers via sophisticated face recognition software. This means if you tell the TV whose faces belong to which users in your family, it personalizes the experience to each recognized family member. If you have friends over, it could log these faces as well.
In addition, the TV listens and responds to specific voice commands. To use the feature, the microphone is active. What concerns us is the integration of both an active camera and microphone. A Samsung representative tells us you can deactivate the voice feature; however this is done via software, not a hard switch like the one you use to turn a room light on or off.
And unlike other TVs, which have cameras and microphones as add-on accessories connected by a single, easily removable USB cable, you can’t just unplug these sensors.
During our demo, unless the face recognition learning feature was activated, there was no indication as to whether the camera (such as a red light) and audio mics are on. And as far as the microphone is concerned there is no way to physically disconnect it or be assured it is not picking up your voice when you don’t intend it to do so.
