I love this dashboard camera.
Quality image is very good, the dual camera returns a great perspective of both sides: driver/passengers and road.
The lens are a kind of fisheye not blurring the side, all the inside of the car is covered and the road including the front of the car.
The settings are simple and easy to setup with several useful features.
Audio is good as well, speech is perfectly understandable and the ambient noise like the engine or open windows are not affecting the audio quality.
GPS is very good and satellites are detected in a minute in cold startup mode. GPS is firmly connected to the equipment.
A very long power supply cable is provided, standard mini USB.
So why just 4 stars?
No software provided, or better, software is embedded in the camera.
When you plug the miniSD memory card and format it, the camera installs a proprietary software in the card, just for Windows OS.
Once the SD is inserted in the computer, the only thing you will find in it is the proprietary software.
If you want to export the recordings you have to do it via this proprietary software.
Software features are very nice as it handles the timeline and the GPS reports, while the video is running it connects to Google Maps and displays the GPS route.
There is no software for Mac or Linux, at least I haven't found any reference on the Internet about that software.
The camera remains a great product I strongly recommend.
