I try to make things clear for those who are too lazy to read.
Out of trouble: deadline for pre-order moved from 5th January to 20th of January (defense purchases Paypal 180 days, so it's okay)
About the camera itself (collected from different locations, for the accuracy can not answer)

The logic of the application with the camera (by video) is very similar to working with Xiaomi YI Action Camera
Perhaps, at the time and the camera and the app will treasure only in Chinese, other languages ​​(Russian) was added later (such xiaomi have happened)
Now, the features of the camera Xiaomi Yi Smart Car DVR Dash Cam (versus Xiaomi YI Action Camera)
In DashSam - 3 Mpix sensor (presumably), and in ActionCam - 16 Mpix, ie under similar sensor size 1 / 2.7 and 1 / 2.8, the pixel size in DashSam - 3.0 * 3.0 Ојm, versus 1.12 Ојm Г— 1.12 Ојm in ActionCam. Thus, for each pixel in DashSam gets more light than the ActionCam. Apparently here and declared the sensitivity DashSam 4 V / Lux-sec. If DashSam sensor and a true 3 megapixel camera, what an advantage in addition to the relatively high sensitivity can be added and no moire in the video. The downside of such a sensor is a low resolution pictures, if the photo mode will generally be in the recorder.
In DashSam lens aperture of 1.8, while ActionCam - by 2.8, that is, a DashSam misses more than 2 times more light than the lens ActionCam. The downside of such lens may be a slight reduction in the depth sharply display space, i.e. In the factory setting the lens focus to the hyperfocal distance, "sharpness" in DashSam will start a little further than that ActionCam, eg 0,5-1m from the camera lens. In fact, this is not a minus, rather feature at the focus drops on the windshield and the hood hardly anyone needs, but on the bonnet and on to infinity it should profit.
Range of recording formats in DashSam modest than that ActionCam. According off.sayta format all 3. Do not think that 2304 * 1296 * 30 less than 1920 * 1080 * 60. The shutter speed and frame rate are two different things. When sufficient light frames clarity (readability numbers) will be higher in the resolution of 2304 * 1296 30K / s. At 1920 * 1080 60k / s to be full motion video, especially useful if you then will slow down. Bitrate 9-14mb / s and 15-20 MB / s - does not provide the very highest quality recording. But this is the best solution to ensure maximum compatibility with all memory cards class10, but also save space on the memory card. Official firmware ActionCam limited to approximately the same bit rate video. This is sufficient for most common tasks, and enthusiast craftsmen gash custom firmware and scripts with a higher bit rate. Most often, such solutions will DashSam for this camera if it is quite popular. If real shot in low light (indoors) will be at a decent level, this DVR is likely to be interested in all sorts of videography, for external power supply of any microUSB from PowerBank.
