The real mini spy cam is a pinhole lens camera only needs a tiny hole to see through, which means that this tiny camera can be placed even further by placing it behind or inside an object or a box with just a tiny hole or slit to see through. Even though the camera is tiny the lens on the camera is 90 degrees which are wide enough to capture any room or office. The three main parts (camera, circuit board, and battery) are able to be separated so it can fit into the tightest areas. This kit also includes an extra-long camera cable. There are several ways to configure this kit so it will work for many applications.
