These may look like ordinary speakers, but there is a spy cam with a 3.7mm wide angle lens cleverly concealed. The Computer Speakers not only work with your PC, but with MP3 players, CD and DVD players as well. They have simplified power and volume control as well as a headphone output jack. Each camera includes a free wireless 2.4 GHz receiver (a $160.00 value.) Available in several models, prices start at $126.00.
