Mio MiVue Touch 638 is the second Full HD dash-cam we’ve tested. Let’s break it down into bits.
Mio Car Camera Review
Accessories and design
The 638 looks a lot like MiVue 688 but boasts a richer choice of grey shades. The display comes in the same size but features touchscreen capabilities on the 638. This way, all physical buttons have been removed, providing a hassle-free setting control.
The first main difference comes from how the charging cable and windshield holder are used. Basically, the charging jack attaches to the windshield holder, and then the whole setup attaches to the camera. This looks like something adapted from older Mio GPS systems, particularly Moov and Spirit models.
I found it difficult to attach and remove the camera from its holder, as you need a high level of precision to match the slider against the rail of the camera. The charger has the same dimensions as Mio MiVue 688 (which I do not particularly enjoy). On the other hand, I found the holder easier to rotate about its latitudinal axis.
Another difference that pushes this FullHD dash-cam higher is the two microSD slots. The overall storage capacity is considerably increased, especially when you want to record longer trips.
Just like the other model, Mio MiVue Touch 638 automatically starts recording as soon as it is powered. It can also be acted upon manually by tapping the Record button on the screen. Output video quality is good, however there is little difference compared with MiVue 688’s Sony sensor. Recording angle is wider, reaching around 150 degrees. The difference isn’t huge, however close-up events, like a car coming up from a secondary street right when you pass it by, might be better recorded.
Below you can check a low-light video sample, recorded at night. You can notice a decent recording quality where all details can be distinguished from the background.
Whether it’s day or night, MiVue Touch 638 is a trustworthy piece of equipment. I hadn’t had the chance to test it out on roads without adequate lightning although I can assume it does just fine.
Settings and features
For those used to tap on smartphone and tablet screens, Mio MiVue 638’s touchscreen comes in really handy. The menu is well structured and features a limited amount of settings which can be used to tweak the camera.
When a shock is produced, the 3-axis camera sensor records it and the event is automatically recorded without overwriting existing data. Shock sensitivity can be adjusted from the menu to reduce the number of false positives.
The anti-glare display provides good visibility in direct sunlight conditions, apart from the speed indicator placed on the right corner of the screen.
Talking about speed, it’s worth mentioning that the camera provides warnings for fixed speed traps with a lifetime update. Warnings are provided both on the screen and by playing a sound.
An integrated GPS system records vehicle coordinates and travel speed which is then displayed on the screen.
Finally, we need to mention MiVue Manager. It offers great info in case of an unfortunate event: direction of travel, speed, etc. You can download it for free on Mio website.
This is a camera that rates about the same as Mio MiVue 688. The major upgrade is touchscreen capability which is probably going to please a lot of users. Lens quality isn’t too much below the aft mentioned model; however the 150 degree view angle is hardly noticeable.
I am not fond of the way the charger blends with the holder and then with the camera, but this is more an accessory issue.
The overall recording quality in low-light conditions is enough for me and honestly, it’s above most no-name dash cams. Many will argue that the price is twice as much as a no-name dash cam. Still, when it comes to road events, where damages can be huge, price is probably the least valuable criteria.
