1. How did it work automatically?
2. How easy was it to install?
3. How was the day and night picture quality?
4. Is the software easy to use?
5. How is the user interface?
1. It turns on automatically when using either the cigarette adapter or the really cool OBD2 adapter. It keeps recording as long as there is power and you have the option to stop recording when there is no movement. It also has what they call a "microwave" sensor (the tube end) that detects motion and will kick the camera on if something moves in front of the camera. I didn't get any recordings of this so perhaps I didn't have anything happen. It automatically deletes the oldest videos. I used a 64GB card so I didn't really run out of space. The files are about 282MB per 3min video clip.
2. It was superbly easy to install. It includes a detachable suction cup that you simply twist the top to adhere to the inside of your windshield. You'll notice metal contacts on the suction cup, I assume that there is a GPS module built into it that talks to the camera. Pretty neat implementation. If you use the cigarette lighter it has a bright blue LED that tells you it's on. I find that kind of annoying. You can twist the blue LED cover and it reveals a USB port - handy for charging your phone. If you use the OBD2 adapter it keeps the camera powered at all times and lets you do recording for security purposes when you are parked. It has a battery failsafe in case it drains your cars battery to prevent leaving you stranded.
3. Day and night picture quality is superb for such a small unit. I put it on par with my x500 1080p camera. License plates, vehicles, landmarks, street signs, etc are all easily identified day or night. I am VERY impressed with the night performance.
4. There's no software. You just get videos. I wish it had some software like the Thinkware which ties in the metadata and shows you the speed/location on a map while the video is playing. It'd probably increase the price but it's handy in case you need to give a good presentation.
5. The user interface is fine - nothing special to write home about. The biggest gripe is that the buttons are on the bottom of the camera. You have no idea what you're hitting while looking at the screen.
Overall the performance is very good - quality is good for a brand new product. The unit sits easily behind a rear view mirror out of the way. The cables are more than long enough so you can stash them behind your headliner and A pillar to reach your cigarette lighter or OBD2 port. It comes on and turns off automatically.
