I was thinking the Palins should get some of that highly-reflective film used for sun-shields. Put it on all the windows facing his house. They could see out, but he would just see reflections. (hopefully...)

Using the device I put a link to, he could still record whispers coming from INSIDE the house from the window glass. I suggest you re-watch the video I linked to. Furtherm infrared cameras record from heat signatures and many home cameras have infrared. Reflective film would do nothing.
