Those who would like to keep a watch over others stealthily check out this Book Camera. In appearance it is just like a normal book but it hides a pinhole camera with a tiny microphone in it. A remote controlled video recorder lets the users make funny videos. Priced at £644.99 (SD memory card extra) the Book Camera is very easy to use. Just leave the book camera anywhere and date-wise record clear colour CCTV images with sound.
