Hewlett-Packard has designed a wearable camera prototype that is easily concealable in an "ordinary" pair of sunglasses. The camera can capture 1.3 megapixel images at 7.5 frames per second or .3 megapixel images at 30 frames per second, storing the images on a portable hard drive. The system continuously records images, but the wearer has to press a button on the device to store the previous 20 seconds and the following 5 minutes of footage on the hard drive. The hard drive will store approximately 3 hours of footage, which just about covers the length of time you will spend trying to convince people that there isn't a hidden camera in your goofy, oversized sunglasses.
