Strong reason to suspect that two way cameras and microphones are in the Television sets. They can look into and listen into your house whenever the Television is plugged in. There was a time in my life when I saw evidence of this in my personal life. It was really like people on live television were like responding to things I said and did. I took note of it. One day I was sitting at a Mc Donalds restaurant and this guy sat near me. He said, those people on the TV can really see you. I did not know that. He said he wanted to go and live out in the woods somewhere and get away from the city. I told him that there was a time when I thought that the people on the TV could see me too, but I thought it was a trick of the devil to deceive me and it was not really so. After thinking about this and based on what I have seen personally, I must conclude that the television sets have hidden cameras and audio equipment in them and people can look and listen into your house through the televisions sets. So unplug the television when you are not watching it. A guy on another website said it can be back engineered from the screen. Probably also back engineered from the speaker. An electron beam moving in a raster could scan the screen like in a video camera, changing light into electrical impulses for transmission. A small portion of the screen used like this would keep power consumption down to be undetectable. The sound could be changed into impulses using a small portion of the speaker diaphram. So you would not find a camera in the set. The camera and microphone are using components already there. You might have the wiring in the yoke coiled a different way and some added circuitry and that is all. It means they could hide it so that you could not be able to tell what it is.
