Try not to leave this camera in the sun. You wouldn't want your lens disappearing in a puff of steam. The camera in question? A USB camera with a liquid lens called the IVIN-2M USB 2.0.
The technology has been around for a few years, but this model claims to be the "first 2-megapixel CMOS digital camera with a variable-focus liquid lens." Talk about a niche.
It's recently been announced by Varioptic and IVA. Practical? Well, it's meant to be used as a surveillance videocam. Impressive specs? It shoots up to only 1,600 x 1,200 at 15fps, but those wet lenses are the kicker, so it's not a total washout. Mass up enough of them in your home and you can trigger a mini-tsunami when they detect a furtive intruder swimming in your pool.
