Spy pen cameras are one of the many types of hidden, wireless cameras. Like spy camera glasses, spy pen cameras are most useful when you want to carry out an investigation without the knowledge of anyone seeing you. The camera in this case is hidden in the pen, which actually doubles as a real working pen. You can keep the pen on your person, on the desk, or even write with itall while the camera captures the image you are focusing on and transmits it.

Spy pen cameras should satisfy the requisites of a mini hidden camera. Size and weight are obvious characteristics. The cameras should have good resolution, range, and battery life and should operate under poor lighting conditions.

The pen camera usually has a transmitter, which transmits the images. At the other end, you can have a receiver that receives the transmitted images and stores or records them. You can also attach it to a monitor so that someone else could be watching the images in another room.

Spy pen cameras could also be still cameras that have the memory to store a specified number of images, which can later be downloaded onto your computer. A cleverly concealed camera inside a working pen makes it the most innocuous yet the most powerful weapon one can have. With up to 180 feet of transmission range and minimal illumination, undercover assignments are a breeze.

A mere click of the pen and it begins transmitting. Whether in your shirt pocket or on the desk or in your hand, you would still transmit live images to the receiver that may be up to 180 feet away.

The possibilities with a spy pen camera abound. Even if you are not a professional investigator, pen cameras could be of use to you. You could take it to meetings, scan and capture documents, or even use it to record what your spouse said to you.
