I've been playing a lot with a wearable camera, except that I've been "wearing" the camera - a ContourHD - on my car. It's a lot of fun, but one of the big problems is getting the framing right. Since the camera has no LCD display, it's very hit-or-miss getting the picture to look good.
I'd previously seen the Drift X170 Action Camera and was intrigued because it has a tiny LCD screen, but it's only standard def.
But now Drift has come out with the Drift HD170, which supports 1080p recording and still has the integrated LCD screen. There's also a remote control! The camera will be available in July with an MSRP of $329.
