There are a lot of spy pens out there, but how many of them can actually record HD like the High Definition Video Pen?
Just as its name suggests, the High Definition Video Pen has the ability to take HD videos in 1280 x 720 resolution which is impressive. It can record for up to five hours and it can store up to 20,000 JPEG images in the devices built-in 8GB memory. The color camera lens is located above the pocket clip, and the microphone on the side of the barrel under the pocket clip. There's also a USB adapter that goes into the built-in port so that you can upload your files.
With the High Definition Video Pen, there's no way that anyone will ever notice you recording -- you could totally ninja the whole thing.
