What's in the box
Delivered is the Yi Dashcam with the most necessary accessories. Included are next to the camera still one 3.5m long USB charging cable, One Vehicle mount with adhesive pad, Car Charging Adapter and a warranty card including an English-speaking one Manual.
"International Version" VS "China Version"
The Yi Dashcam is as international versionbut also as Chinese version available. Before you buy, you should make sure that you acquire the international version, which offers an English language interface. The Chinese variant is often sold in Chinese online shops. This is completely in Chinese and the language can only be changed over indirectly!
Design & Processing
The overall design of the Dashcam is visually appealing, modern and compact at the same time (74 x 32 x 19 mm), The camera is available with a anthracite or gold Front. The processing is according to the price. The entire camera is made of plastic and is processed neatly. Only the case frame looks a bit cheap at first glance. Also, the front lens is a bit too big for my taste and could be a bit simpler.
The included mount of the Yi camera is also made of plastic. The integrated ball joint allows the holder to be moved in any direction. Improvement is the possibility of attachment. Instead of an adhesive pad, a suction cup would have been an advantage!
Hardware & Equipment
Image processor and image sensor
According to Yi Technology, the Dashcam has one "A12 image processor" installed. This is actually one Novatek NT96660, which is also installed in Chinese action cameras. The image sensor amounts to one Semiconductor AR0230CS, In combination, a maximum resolution of 1296p with 30 pictures-per-second allows. With a resolution of 1080p are even liquid 60 images-per-second possible. The aperture ratio is F 1.8. The maximum field of view is 165 °.
On the back is a 2.7 inch TFT displaywhich explodes with 960 x 240 pixels. Colors are so well represented. Depending on the viewing angle, however, these can fade.

A Microphone is located below the front lens. To power the Dashcam has a Micro USB socket, Although it is also a 240mAh battery but this serves as a pure emergency supply. The maximum battery life is about 3 minutes. To save recordings is on the left side of the case Micro SD memory card slot, Compatible are 8-64 GB Class 10 memory cards in FAT32 format.
In a good two-week trial, we have collected several recordings in 1296p and 1080p. Both in good and in bad weather conditions, the shots were sufficiently sharp and detailed. A sharpness and a richness of detail, similar to a GoPro Action Cam is of course not to be expected. On the pictures were Identify the license plate well and through the wide field of vision is the entire road well visible.
By WDR 2.0 technology The image is adapted very quickly to the current lighting conditions. For example, if you drive the vehicle out of a dark underground car park, the Yi Dashcam immediately adapts to the light conditions and details remain visible. Even at night, the Xiaomi Yi Dashcam convince. An image noise is barely visible. Only the details are lost a bit. The recording quality of the microphone is sufficient. Conversations are clearly recorded, but the sound is a bit dull. Disturbing vehicle noise, however, are filtered well.
Menu and App
The usability of the Dashcam menu is simple and understandable. Overall there is 4 control buttons, These can be used to start recordings, you can switch to the gallery, watch recordings via the camera and there is a switch-on or adjustment button. The menu is clearly arranged and the menu is easy to handle.
The "Yi Dashcam" App is the mobile control center of the Dashcam. This is for both Android, as well as for Apple iOS available. The language of the app is English. In the main overview recordings of other users can be viewed, as well as share your own recordings. The camera can be used to transfer pictures from the camera to the smartphone. Anyone who has misplaced the Dashcam's operating instructions can retrieve them via the app.
A connection between smartphone / tablet and the camera is made via WiFi. The Yi Dashcam builds a dedicated Wi-Fi network to which the app can be connected in a few steps. With an existing connection, the settings of the camera can be made directly via the connected device. A live image output is also available, as well as recordings can be started directly from the connected device.
ADAS (driving assistant)
ADAS stands for Advanced Driver Assistance Systems, The ADAS of the Yi Dashcam indicates lane change and reminds you to drive up to the vehicle in front of you. In the test, the ADAS could not convince. Despite correct calibration and alignment, lane changes were displayed incorrectly. During the trip, many people warned about a vehicle in front that did not exist at all. The warnings are in bad English, which is more annoying than useful in the long term.
