Here is a miniature camera that lets you capture 1080p video and 12MP photos anywhere. The QliCam is pretty easy to use. Just start it up, stick it to any surface, and start shooting. Since it has night vision, the QliCam can record high quality video day or night. With a magnetic disk, you can attach the camera onto almost any surface.
QliCam features motion detection, so it can start recording only when motion is detected. You can get one for as low as $29 if you are an early supporter.
