Have a roommate that likes to borrow clothes? How about a coworker who likes to take all of your paper clips? If you have a sneaking suspicion that someone is meddling in things they ought not meddle in, then you’re going to want proof that something is up. Installing security equipment is taking things a bit far, but you can always downsize and still get the job done without anyone noticing.

The Spycam Pen Camera is exactly what you need to stop wrongdoers in their tracks. It can take pictures, and record video or audio depending on what you need. There is 8 GB of storage, and it can film at 720p for up to two hours on a battery. There’s a USB cable that will let you download all of your newly captured footage, and the whole whole kit and caboodle comes in at around $40. Obviously, this would be a terrible spy pen if it didn’t actually write, so you can record and take notes of odd behavior at the same time.
