The $100 Swann DVR410 RemoteCam is a digital camera shaped like a car remote control. The camera lens and microphone are located on the front, and buttons are unmarked so no one will suspect it's anything more than an ordinary car remote.
It records up to 40 minutes of footage onto a 2GB SD card with a resolution of 720x480 in full color. Still-image capture is also possible at up to 1,280x1,024-pixel resolution. It has a built-in microphone, with an audio range of about 10 feet.
As with any spy camera, you can use the DVR410 for good or mischief. So record responsibly. And remember, no matter how much this looks like a real car remote, if you point it at people long enough, they're probably going to suspect something's amiss.
