I have always like to watch my wife play with herself. She is shy and don't like to give me a first hand look. I have had some sort of cam in the Bedroom for years. If she found it I would hand her a line that it was no op or it was some other device to help TV reception. My Dlink system recorder did not like to change to 2020. I was not pleased with that system in my new house. Bedroom is large and camera far and resolution was not great. Anyway, I up graded to a home security system with HD cameras. They are meant for outdoors. they are large. I put one in the bedroom. The wife noticed and asked about it. She asked if I was watching her. Told her I was putting in a security system and I was looking at where to place the cameras. Told her I was watching the sliding door to the patio. She never asked to see the monitor picture of what I see. centered on the bed. Right after that she seemed to put on a great vibrator and dildo show. Hiding in plane sight Wish They would make a smaller camera.
