Long Range Laser Listening Device

This is another eavesdropping device that can be used from hundreds of feet away. It works by using a laser pointed at a window and then having a Cadmium Sulfide Photocell capture the laser reflection. The photocell is then connected to a headphone cord which is connected to your computer. Then, all that you need to do is open a sound recording system that you use on your computer and click record. And there you have it, for more information click here.
