Mini Gadgets Inc. has got you covered -- and by covered, we mean they make what you're looking for, buddy. The Black Box DVR is a personal video recorder which features a tethered camera, and can utilize a miniSD card up to 4GB. The company's website claims it's the world's smallest DVR under $3000, and we're inclined to agree -- at 2.28 square inches, it doesn't get much smaller. The device can record 640 x 480 video at 30fps, and includes a "long lasting" Li-Ion battery, for when you're on the go... shooting secret videos. Available right now for the shockingly low price of $499.95.
