Spy pen cameras are literally a pen and a digital camera combined. You just have to tap on the button and since it has an audio recorder along with a video recorder; it would start collecting both for you. The one-button operation makes this low-key device a very cool and portable option to be. The size of the pen camera doesn't parallel the quality of the picture. The camera can be smaller in size but with nice picture quality. Also, along with the recording, you can use this spy camera to take pictures too!
