where to hide my hidden camera?

I need to place a camera in my bedroom to make sure the cleaning lady is not taking anything. Things always seem to be misplaced, moved, missing, etc. I have a tiny wireless spy camera that runs on a 9Volt battery. Here is the link to it,http://www.amazon.com/gp/product/B000BL1N54/102-0620414-7549762

i have to make sure she won’t see it since she cleans everywhere. I was thinking on top of the curtain rod (place the battery clip behind it and have the pinhole barely showing. I having real trouble. If anyone knows of a really good place where she would least suspect it I would appreciate it.
