A spy pen audio device can endure hours of active recording without running out or needing to be recharged.

After you’ve written all you want, you scan your notes into an app to digitize them, and when you’re all done, you just wipe the pages off with a damp cloth—they even include a microfiber towel to get you started. The E-P7 features the same new autofocus system as the E-M10 Mark IV –it's still a contrast-based AF system, but is night and day better than that of the PEN-F or any of the preceding E-PL cameras. With 4,096 levels of pressure sensitivity, two side buttons to change settings or tools, and a sturdy frame, this pen is perfect for those looking to use Wacom Active ES tech or the Microsoft Pen Protocol.

You can control apps remotely by using the S Pen connected to your device via Bluetooth Low Energy (BLE).

This spy pen features a small pen camera that can deliver 1080p HD videos and photos and will prove useful in your classes or at the workplace. I mean it’s really hard to get your head around the over-complicated phrases and obvious cut and paste job from Google Translate. This camera finally catches the PEN line up with the power of the OM-D bodies –putting a stunning stills camera in your pocket, for one of the best travel and take-anywhere systems we've used. For example, take a shot of a flower with pinpoint focus by pressing the area of the screen you want to shoot or capture the perfect selfie with one touch. Of course it's not as supernatural as the phase detect system of the Olympus OM-D E-M5 Mark III and Olympus OM-D E-M1 Mark III, but the face and eye detect are very reliable in both stills and video shooting.

With so many 2-in-1 laptops offering active stylus input, it makes sense to take advantage of this handy bit of technology. This spy pen features a Motion Detection option, so you can leave your pen on stand-by and wait for a motion-activated secret video of anyone or anything you wish to record. You can also connect your pen to your phone or tablet via Bluetooth to have your notes sync to the Livescribe+ app. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.

You get the pen, five refills, a card reader, USB cable and even a lens cleaning towel to ensure your videos remain clear and free of dust on the lens.

Interestingly, the E-P7 doesn't come with a battery charger in the box –instead it features a USB passthrough connection to recharge the battery in-camera. Screen resolution – As in any recording device, you need your spy pen to have a screen resolution that is high enough to view the videos for loop recording. If you are experiencing difficulties with your Samsung mobile, tablet, or wearables, you can send us a question in the Samsung Members app.

It can also record at 720p (60fps), so you can adjust your settings better to your battery or storage needs. And when you pair the pen with the Livescribe+ app, it goes beyond just writing and drawing, as you can create audio recordings that sync with your handwritten notes, giving you more detail or context to what you’ve written.

This is because a camera that has a higher resolution will give you a very thorough view of whatever is going on in the video. If you don’t want to sync often, look for a pen that has a lot of memory; the Livescribe models have generally large amounts of storage. With its pen-like design, you can easily conceal it from everyone by putting it in your chest pocket, pencil stand, or office desk.
