I have just taken delivery of an unfortunately named
Gitup Git 2 (pro packaging) which I bought on
eBay from estore009 for £99. I chose this particular camera after reading and watching stuff at
Dashcamtalk and
Techmoan. It's the same physical size as a
Gopro Hero 3+ apparently and is fully compatible with the Gopro ecosystem of mounts, brackets, harnesses, waterproof cases etc.
The package I bought was supposed to include a selection of extra mounts and a carrying case (on top of the accessories that Gitup include in the pro package) but this didn't arrive with the camera and to date hasn't arrived yet from estore009. I have been in correspodence with estore; they say they have sent the outstanding items but they haven't arrived yet... I think the post is still catching up after the hols! It won't be a big deal if the extra accessories don't arrive really, the camera and included accessories are still good value at £99 delivered.
I don't intend to use the camera as a dashcam but after watching Techmoans channel, I am assured that the basic dash cam requirements (file/video looping and automatically powering off and on with the ignition) are met by this camera. Apparently the video quality in low light (i.e. at night) isn't as good as dedicated dash cams. You might also want to consider if you would really want to leave something that looks like a Gopro permanently attached to your windscreen when parked.
Incidentally, I was in a cab the other day and in conversation with the driver. He had a dash cam that was a chinese cheapo from eBay (I think he said about £20). It appeared good enough for the task and didn't look like anything you would want to steal.
Anyway, if you can bear to look at my fugly mug, there's some sample footage here. Youtube doesn't do it justice though, the original file quality is excellent. My other videos (shot with an old Contour HD helmet camera at 720p, 30fps) don't seem to as badly affected.
