The video quality that KF concepts camera records is pretty decent especially at night, however I ran into several problems with it. First, the camera is shipped with the default language set to Chinese. The manual is not detailed and has no information on how to change the language. I had to manually select every option on the menus one by one remembering what I already looked at by position (I do not read Chinese) until I found a menu choice that allowed me to switch the menus to English. I show where that option is located in my video. The second problem was the mount does not stay on the windshield during cold weather. We had a cold stretch of weather (12°F in the morning) and the suction cup mount does not stay on the windshield at this temperature. In the afternoons when the weather warms up I am able to mount it and stays for as long as I need. So if you live in a cold weather this dash cam will not work well for you. The mount is custom made for this camera, so you cannot replace it with another better mount.
On the positive side I like that the dash cam's compact size (2.25" x 2.25" x 0.75"). It does not block much of the windshield. The video quality is fine. It is not as good as 4K cameras, but quite reasonable and it does quite well at night. My video includes snippets under various conditions - day and night. 170° wide angle lens gives a good view of the entire road.
It turns on as soon as it gets power so you don't have to remember to turn it on. It can be turned off manually if desired. It is powered by a regular mini USB cable. The package includes a 32GB Class 10 micro SD.
When the dash cam writes out files to disks it saves them every few minutes, this is good, because if there is a problem you lose just a small segment not the entire video. I have not had any corrupted files with camera, but from experience with other cameras I now it can happen. I should note that the camera does not write out files to a standard directories. It creates three directories: event, jpg, and video. It uses JPG directory instead of DCIM for photos.
I received this camera for testing and review as part of a new product introduction. Overall, the camera has its pros and con. Hopefully, the manufacturer will fix the default language in the future versions of the camera, and I provided some help in how to do it now. So the only serious issue here is for the folks in the cold climates is the issue with the mount.
