Some About Spy Camera Pen Recorder

There are many spy camera pens on the market – some color, some black and white and some audio. Certain cameras do all the above, others just take pictures or record sound. All of our 2g/4g/8g spy pen camcorders sold there are multi-function type.

Use one at home to keep tabs on your private belongings, or on vacation – see what the hotel staff are up to in your room.

Even sneak one in to a trade show – get secret pictures of new technology.

Video Spy Pen - You can slip it in to your pocket, then click the button for instant color pictures and audio recording. The picture quality is high, the audio is clear enough.

You can easily attach the receiver to a TV or VCR to record your surveillance footage.
The only issue is you need the receiver (you get this included) to be within 100 meters and in line of sight of the spy pen – this does limit your uses for using a video spy pen so unless highly important a combination of the still camera pen and the audio pen offer great mobility and detailed surveillance possibilities.

Digital Image Spy Pen - The pen is totally self sufficient and can be carried anywhere - perfect for on the move surveillance.
This digital camera spy pen looks totally normal and writes totally normal as well. No one will know that you're taking their picture. The 36 pictures it stores in its 2MB memory are good enough in quality for recording documents, files or regular images. The focus and exposure is all auto, and the battery life seems very long (they say 500 pictures but it seems more).

Audio Spy Pen Camera - The audio spy pen is another one suited for "on the move" surveillance (it's worth considering to take both; a still image and an audio spy pen to cover all eventualities.
My favorite audio spy pen is digital, has 128 MB of memory, can record up to 8 hours of audio - it can be carried and used anywhere. You can disguise it as a key-ring with the parts included and it is internally rechargeable – no batteries to replace.
