Today’s smart TVs offer come with security and privacy risks that most of us never think could come from a TV. These TVs are not just outputting information; they are taking in, storing and sending information to third parties. What are they taking in you might ask? Smart TVs are recording what channels you watch, what shows you watch, the time you view them, and if you recorded the content. Most threating to your personal privacy, newer smart TVs are recording voice and video if the smart TV is equipped with a microphone or camera.

Remember the Nielson ratings? Many years ago Nielson would call households and collect information on what you were watching. They had various ways to entice people to participate in their phone surveys, but had no real way to verify if what you told them you were watch was actually the shows you were watching and if so for how long you were watching it. Well since the advent of TV top cable boxes, and now with smart TVs, this information is collected from millions in real-time. That’s right, what you watch is being recorded and sent to media survey companies and many other companies interested in this data, in real-time, while you are watching it. In fact some TVs with microphones and cameras are recording voice and data at times when you don’t realize it.

Smart TV Security Settings
Carefully review your smart TVs settings and opt for the most restricted settings. Understand your smart TV settings and change them to protect you privacy. Below are some settings to focus on to reduce security risk and privacy intrusion. Note that not all smart TVs have microphones or cameras installed and all TV settings differ from model to model.
- Turn off data sharing in the TV settings
- Turn off the TVs microphone in the TV settings (if one is installed)
- Turn off the smart TVs camera (if one is installed)
- Physically block your TVs camera (if one is installed.) This can be accomplished by tape or other means. Most of us have done this on our laptop cameras to protect our privacy on those devices
- Do not connect your smart TV to the internet. Ultimately you can opt not to connect your smart TV to the internet. Understand, however, that doing so will severely limit the functionality of the TV and in essence will eliminate any benefit of having a smart TV
Keep in mind that by turning off your microphone and camera in the TV settings may appear to render your microphone or camera inoperative. But do we know for sure? It may only render the use of the camera and microphone for your use inoperable, but may still be in standby mode to record and transmit information on your usage of the device. We can never be sure. So exercise on the side of caution when setting up and using your smart TV.
Hackers and viruses can also get into your unprotected smart TV and then into your router.
