CiBest® 2.7-inch HD 720P Car LED IR Vehicle Camera SOS Dual Lens Recorder Car DVR Driving Recorder with G-Sensor F20
It has the dual channel video which I really like.  Its high def video is great during day light but the night mode doesn't work at night at all; can't see anything other than blurring light from car and street light.  User manual has English and Chinese translation which I can read both but both are difficult to understand.
