How much do you think it would cost to buy a video camera about two-thirds the size of a box of matches, capable of taking images at low-light levels and with a resolution of 380 lines or more?

In fact, it's possible to pick up a camera that even James Bond's legendary M would be proud of for just under £60 (less than $100). For a little extra, the camera comes already concealed in a smoke alarm, intruder detector, clock, filing book or other innocuous piece of everyday equipment.
