From other vendors I've already returned 2 camera types because details were only blurred to recognize and record often had long gaps minutes on a Class 10 SD card between each 3-5 minute sequences. When Rollei Car DVR-100 I have no problems. The instructions about the settings on the camera is easy and done in a few seconds, all in good German easily readable. In the pictures on the Internet, the device looks a lot bigger than it actually is. With me in the 3-series BMW, the part will disappear almost completely behind the rearview mirror. The image quality of the evaluation on the PC is comparable to an average camcorder. Of the vehicles in front the indicator is clearly legible. When oncoming vehicles in a speed range over 30 km / h I have seen more problems plate. Certainly can fetch in the event of damage from the shots more out with special software. The unit turns on exactly with the start of the car, and after switching off within 10 seconds. Again. The automatic monitoring also works very well as long as the internal battery keeps the device switches automatically for a short period on record. When the camera detects motion and swaying in the wind trees or shrubs in front of vehicle. A night scene with infrared light is not possible with this device, with the other devices I had with infrared, I saw at night, only the strong reflection of infrared diodes in the front window, so I surrenders same for this part. The GPS, as it exists at the larger (more expensive) brother, I also do not need, because it would always betray your speed exactly. The audio recording of the interior noise work clear and understandable, so you can based on revolving radio broadcasts or occupants comments a conclusive time and other information, such as the driver recognized mark, store quickly and effectively. (If you go for a walk in the car the beloved, you should because of his own wife, turn off the sound recording prefer beforehand.) Here again my conclusion after the first days of my tests: - Very good picture quality and good detail recognition - Easy operation (instructions in German) - Secure recording (have TS32GUSDHC10E Transcend Class 10 Extreme Speed microSDHC 32GB card) - Good sound quality of the interior noise (luckily switched off) - Solid suction cup for attachment to the windshield or rear window (standing or hanging installation possible) - Functioning Motion Detection - Relatively long cable with which you certainly get to the cigarette lighter or a power outlet inside.
From me there is a strong buy recommendation. Let's see, maybe I'm considering another to the monitoring of the rear window to the rear. Those who, like I had to prove his innocence already 2 times, are better for such a technique a few bucks from when for incompetent lawyers or German courts. Greetings Jürgen A.
