The OpTex Pen Cam is a covert surveillance camera inserted in a chunky ball pen casing, with the lens next to the pocketclip and the microphone on the top of the cap. The Pen Cam incorporates a 3. 7mm pinhole lens, a 1/3' inter line colour CCD-camera and an FET amplified microphone. The output signal travels down a cable attached to the bottom of the pen casing, which can be passed through a hole in the pocket where the pen is placed, allowing it to be concealed inside the lining of the jacket. The video and audio signals can be fed directly into a recorder or via one of the OpTex miniature 10 mW, 60 mW or 400 mW microwave transmission systems for remote parallel surveillance and/ or recording.
