This has not been a review, as it is, but more my experience and my thoughts about the GX1600. Other users may well view the GX1600 in a different light. I could have gone much deeper into the app and the camera, but for the U.S. market, the camera did not warrant it. It is a well-made camera, but it seems to have been hobbled in order to fit into a non-U.S. market. I think if some items were better polished and the image improved, the GX1600 would have been a pretty darn good 4K/2K dashcam.
Would I recommend this FineVu GX1600 for the U.S. market? The fact that, after 1 telephone call to the Support answering service and 3 email attempts to the Support group, all resulting in no response from FineVu, the answer would be "No". Compound that with the fact that when attempting to register the GX1600, the FineVu site said the serial number was not valid for the GX1600.
The GX1600 never failed to work or go into parking mode. It was perfect in that sense, but it also has a few nuances of its own. One is that the WiFi cannot be turned off; it is always on unless the car is in parking mode. As the GX1600 is not a Cloud camera, there is no need to keep the WiFi on all the time. Even if it were Cloud capable, no need to have WiFi on all the time.
Another is that the rear camera can not be disabled. When powering the camera for the first time without the rear camera attached, the GX1600 will prompt you to check your connections. As long as the camera is powered or in parking mode, the rear camera warning is not heard. When power is completely removed from the GX1600, then the rear camera warning will be heard on the next power-up cycle.
Some items lack 'polish'. When using the app and in LiveView, the Mirror feature not only reverses the displayed image but also reverses the two information lines that show GPS, Logo, etc. That is embarrassing in my estimate. The Zoom feature works, but as you zoom in, the image becomes increasingly out of focus, so it's essentially useless. There are two information lines for the data: one at the top and a shorter one at the bottom. The FineVu logo cannot be removed, but the GPS can. Neither line can be entirely removed. When switching from LiveView Portrait to LiveView Landscape, the fonts degrade and begin to resemble CGA fonts.
The ADAS features worked well. These are not Tesla-level features, so ADAS responses were non-AI in how they responded to a driving event, but they did work and worked fairly well.
The app worked very well, was visually appealing, and was reasonably well organized. A few words could have been a bit better 'Americanized' in English, but it was still obvious what was being conveyed. The app quickly negotiated WiFi connections, which was much appreciated. The overall build quality of the GX1600 is very good. The housing, board, components, and cooling were well thought out. My unit did have buttons that rattled, and the noise was evident on videos. I do not know if this was a one-off incident or a design flaw. I did remedy that, as noted in a previous post. I will return to the buttons and see if I can find a more elegant way to halt the rattle.
The GX1600 is a 4K/2K dashcam system, but its 4K image quality is where it lags. This was surprising as FineVu implies STARVIS 2 for both the front and rear cameras. Or so it seems to me from reading their advertisements. As their Support never responded to my attempts to contact them, I was unable to verify which CMOS was being used. The 2K could have been better in terms of image quality, but it was good enough for a passing grade. Oddly enough, with the front 4K, almost every time I paused the video to read a car license plate, the plate was easy to read. At the same time, there would be other image issues on the front camera. Not bad issues, but certainly the image could be better. On the other hand, the CMOS would be slow to show light changes in the sky; often, I would see a cloud display a 'flash' of color change or a fade. Whether using 4K30 and 2K60 on the front, the image was always good enough to see what was going on around the car easily.
For the price, I do not believe the GX1600 is worth it in the U.S., not in the American market anyway. There are dashcams available with better image quality for the same or less money. The GX1600 does not appear to be designed for the U.S. market, but rather for other markets. The feature set, the way they are implemented, and the lack of programmable options will not go over too well in the American market. The GX1600 is not a bad dashcam; it is actually a good one, but it isn't for the American market.
