Specification :

The cap has a secret lining inside that hides a high grade CCD video camera that shoots through a pinhole you' d need a magnifying glass to see. The special covert secret lining can also hides a digital video recorder. You have a completely self-contained covert video recording system like nothing else on the market! The camera is positioned in a place dead-center of the cap so the video recording records what you see with your eyes. No need to worry about aiming, positioning, wires, wireless connections or anything else since the camera wires are built right into the cap. Just put on the cap and you are ready to conduct covert video operations!
