I have had the K&F Concept installed in my car for a few weeks now. Installation is actually quite easy with the included fuse adapter. First, position the cam on the windshield and then attach it with the suction cup, which is also included in the packaging. But I immediately ordered the GPS base and used it. Then you lay the cable. But BE CAREFUL on the A-pillar because of the airback. The cable should be laid in such a way that it does not affect the airback and its function. It is best to run it down the window, not the door seal. Then you take the appropriate adapter for your fuse, plug it into the cam cable and pull out a live fuse in order to plug in the adapter. The fuse is then plugged into the adapter, So there are practically two fuses on the adapter. One for the cam and the other for the circuit it is responsible for. But be careful with the adapter, it only works if it is plugged in correctly. If the cam does not turn on, the adapter should be plugged in the other way around. The continuous current is needed for parking mode. Motion is detected via the image sensor. If something moves, the camera records a short sequence. With fast movements like a moving car, the motion detection is usually a little late and you can only see the car driving out of the picture. The image quality is good to very good during the day. You can only see the license plate of oncoming traffic shortly before it passes. But if you stop the video from playing, you can see them earlier. The image quality of the interior camera is good at night and good to very good during the day, depending on the lighting conditions. Now about the camera's night vision. I'll put it this way: where there is no light, even the best and most expensive camera can't see anything. The situation is similar with oncoming traffic, but there is too much light and the camera is partially blinded. When you drive through towns and cities you don't actually get a very good picture due to the street lighting. You also have to consider what kind of small lens and mini image sensor is built into this cam. The image quality depends on the software installed in the camera. If you use this dashcam to document your vacation trip, a parking collision or an accident, it is completely sufficient.
