Since the launch of MiVue 8 series products, which are flagship models in 2020 , Mio has continuously updated the new models of the 8 series to expand the front line, from MiVue 838, 848, 852, 856 to 4K graphics in August this year. The high-quality MiVue 887, each product can be said to have evolution in design, specifications or additional functions. As for the MiVue 890D tested this time, it is the latest driving recorder product launched by Mio in October this year. When you see the "D" at the back of the model, you can know that this is a dual-lens series product that can provide more comprehensive protection. Simply put, it is the combination of the "MiVue 890" front lens host and the "MiVue S60" rear lens. The biggest point is that the S60 rear lens has now evolved to 2K video quality, and this is also the first rear lens product with 2K video quality in the Taiwan market. As the latest model of the flagship 8 series, the front and rear lenses of MiVue 890D are of course starlight-level photosensitive elements, capable of high-quality synchronous video recording of up to 2K (1440P) and 30fps in front and rear. Parking mode, as well as the latest third-generation safety warning six-in-one and other practical additional functions.

The body shape of the 890 is exactly the same as that of the MiVue 887, which featured 4K image quality before. The lens part is of course Sony's star-level STARVIS sensor BCX71JLT1 model">BCX71JLT1 model">BCX71JLT1 model">BCX71JLT1 model">BCX71JLT1 model">BCX71JLT1 model">BCX71JLT1, the maximum wide-angle up to 140 degrees. It is worth noting that when the 890D is used alone, it can use up to 1440p/60fps video resolution, but limited by the computing power, when paired with the S60 rear lens dual-lens video recording, the highest resolution of the front and rear cameras is 1440P/30fps.

The top of the fuselage is where the bracket is fixed. In addition to the power cable jack, there is a small round hole on the side that is used to connect the rear lens of the S60.

The 890 is equipped with a micro SD card slot and four operation buttons on both sides of the fuselage. The memory card part supports up to 256G model > 256G model > 256G model > 256G model > 256G model > 256G, Mio stated in the notes on the official website that Micro SD memory cards are recommended to use 16G or higher, Class 10 or higher high-speed cards , it needs to be formatted in the machine before use. When using dual-lens video recording, the memory card needs to be at least 16G, and because 4K, 2K/60fps, 2K/HDR and other high-resolution file archives are written at high speed, it is necessary to use U3 or V30 For the above high-speed memory cards, the last thing to note is that "SanDisk series memory cards are not supported." It is recommended to choose MLC process or dedicated memory cards for driving recorders. Of course, after using the memory card for a period of time, you should also remember to format it regularly to ensure normal function.

The front lens bracket is the same as the previous 887, with a universal joint to adjust the position of the lens, and the rear is 3M adhesive that can be closely attached to the electrostatic sticker.

The rear lens is quite compact, and its volume is similar to that of A50, A60 and other rear lens products that are "hidden". The lens is also a Sony starlight-level STARVIS sensor, which can provide 1440P/30fps, 1080P/50fps, 1080P/30fps and other shooting resolution options. In addition, it should be noted that at present, the S60 rear lens can only be used with the MiVue 890 front lens, and other models cannot be used as options.

The front of the MiVue 890 is equipped with a 3-inch IPS wide-view high-definition screen with automatic brightness adjustment function. When the light is sufficient during the day, it will automatically increase the brightness to enhance the recognition. The screen doesn't look too dazzling.

Like Mio's previous products, there are four control buttons on the side of the fuselage, from top to bottom, they are menu, manual custom speed camera, manual photo, manual event recording and other functions. Of course, manual photography and event video recording are both front and rear shots.

After the installation is complete, don’t forget to adjust the resolution settings of the front and rear lenses first. It can be seen that when the front and rear mirrors are used at the same time, the maximum resolution of the front and rear lenses in the menu is 1440p/30fps, that is, the front and rear are 2K. video recording. For those who especially want to shoot high frame rate video, FHD 1080p -ic/" title="1080p model">1080p-ic/" title="1080p model">1080p-ic/" title is also available in the menu ="1080p model">1080p-ic/" title="1080p model">1080p-ic/" title="1080p model">1080p-ic/" title="1080p model">1080p first 60fps, last 50fps shooting options.

The EV value of the front and rear lenses can be adjusted in seven steps, and the exposure value of the lens can be adjusted according to the needs to record videos with moderate brightness. In addition, some car owners should remember to increase the EV value when the heat insulation paper is too dark so that the film will not be shot. Too dark video.

In addition to the six-in-one security warning, many of the conveniences of the MiVue 887 also carry over to the 890D, including the "Write in Seconds" function that is particularly emphasized on the specification sheet. This is because in the past, most of the driving recorders used MP4 files written in units of "minutes". If the file is damaged somewhere, the entire video cannot be read; if "write in seconds" is allowed, then Except for the files that are damaged in that second, the rest of the files can still be read, avoiding the situation of missing key images; it is worth mentioning that the technology adopted by Mio is not the common TS stream that is written in seconds in commercially available models. And still the mainstream Super MP4 (H.264) file, the advantage is that it has the highest compatibility and allows you to watch it on different systems and devices. The content recorded by the driving recorder will be classified into folders such as Event (event), Photo (photo), Video (video), etc., and the videos recorded by the front and rear cameras will also be divided into "F" in each folder. The two folders with "R" are convenient for users to quickly find the required clips.

Download the "MiVue Manager" video playback software on your computer, you can simultaneously display the vehicle speed, direction, altitude, longitude and latitude, direction G value or Google Map path and exact position while playing the file. 4. 1/2 slow motion or 1.5, 2 times speed playback; in addition, you can also print the screen, backup, take a video, save a new file, or upload to Youtube, which can be said to be quite powerful, but it should be noted that this The video played by the software has a low resolution. If you want to watch a high-resolution video, you still need to use the video playback software on the computer directly. It is a pity that the 890D does not have the previous Wi-Fi connection function, so it cannot be combined with the "Mivue Pro" application in the mobile phone to directly set the machine on the mobile phone, watch/download the video screen or perform OTA update.

Press the camera button for 2 seconds to switch the image display mode of the main screen. Not only can the front lens/rear lens screen be displayed separately, but also the front and rear mirror images can be simultaneously displayed in a picture-in-picture mode.

In the past, the driving recorder was like an invisible protective shield. Usually, you would not be aware of its existence. Only in the event of an accident would you think of calling up the video screen, but after adding the "speed camera" warning, it will be different. , after all, this is a practical add-on that you use every day on the road. In order to rectify traffic, the current law enforcement methods are changing with each passing day. From the previous fixed/mobile speed cameras, to "zone speed measurement", and even the "technical law enforcement" of new instruments, all of them give you the chance to accidentally receive a red ticket. greatly increase. When it comes to the "speed camera" warning, this is a useful function that Mio has added to its various models a long time ago. The point is that the function has been continuously evolving. For example, since the end of last year, Mio has begun to provide a variety of MiVue 8. The series of driving recorders have built-in "Dynamic Zone Speed Detection Camera Reminder". This year, MiVue 887 has launched the first "Safety Warning 6-in-1" function. In short, it is in addition to the original "General Warning and Patent Dynamic Warning" ” and “Dynamic interval speed measurement warning”, four additional warning functions including “Technology Law Enforcement Warning”, “Elevated Fixed Speed Measurement Warning”, “Mobile Speed Measurement Fixed-point Warning” and “Steerable Fixed Speed Measurement Warning” have been added. As for the 890D Of course, it is equipped with the latest third-generation security warning six-in-one system, which can provide more complete early warning protection than before, allowing you to greatly reduce the chance of receiving a ticket! Although it is the latest function, some previous MiVue 7 series, 8 series and other products can be updated, and if they have Wi-Fi function, they can be updated through a convenient OTA method.

General warning and patented dynamic warning: The so-called "general warning" is the same as most of the driving recorders on the market, and a warning is issued at a fixed distance before the fixed speed camera to remind the driver; as for Mio's "patented dynamic warning", it will be The faster the speed is, the earlier the warning is issued so that the driver can respond earlier.

Dynamic zone speed detection warning: It is a warning function for the "zone speed measurement" road section, and three indicators such as built-in real-time speeding reminder, safe passage countdown, and whole-process warning screen remind drivers whether they are speeding. As for the tunnel without GPS signal, It will calculate the time required to pass the road section according to the speed limit and distance, and let the car owner know whether it is speeding with a "countdown second".

Technology Law Enforcement Warning: Speed cameras are not the only things that will get you a ticket. Many road sections now use image recognition technology or illegal video reporting. This is the so-called "technology law enforcement". The road sections that appear will now also warn drivers in advance with pictures and sounds.

Mobile speed detection fixed-point warning: voice and picture reminders are provided on the road sections where there are often mobile detection speed cameras (that is, mobile tripods).

Elevated fixed speed measurement warning: When driving on a three-dimensional road network (such as an elevated road), a warning can be issued in advance for the elevated speed measurement section.

Steerable fixed speed detection warning: This function is to issue a warning in advance for the two-way or steerable fixed speed measurement on the driving section.

The most commonly encountered on the road is the fixed speed camera. At this time, the 890D will not only give a voice prompt, but the screen will switch to the warning screen, showing the road speed limit, the current speed, and the remaining distance to the speed camera. The "general warning" that warns the distance, Mio's "patented dynamic warning" is very useful. In actual use of the highway, the warning will be issued about 600 to 700 meters before. The warning was issued only 100 meters ago; in addition, another key point of evolution is that the 890D's remaining distance prompt is more accurate, and there will be no situation where the distance is still counted down in the past but has passed the speed camera pole.

When encountering a section with speed measurement ahead, it will also warn the driver with a warning sound and information such as speed, speed limit, remaining distance, etc., and in a tunnel without GPS signal, the screen will change to display the countdown seconds. After the countdown time on the screen is over, you will not be overspeeding when you pass the end point, which is a fairly simple way to judge.

The speed camera warning on elevated roads is also a new feature, but after all, the location of the speed camera is marked with GPS coordinates, so sometimes when driving on elevated roads or highways, the speed camera warning on flat roads will occasionally jump out.

As before, the 890D also has the "custom speed camera" function. When you are walking on a certain road section and suddenly find a set of mobile tripods or traffic police with speed guns, you can immediately press the manual new speed camera button. Let the machine store this location information (up to 100 can be customized), and the next time you pass this road section, it will issue a speed camera warning to avoid being shot.

In addition to protecting driving safety, Mio 890D also has a "parking monitoring" mode that can also protect the safety of your car when you park. And this "smart three-in-one parking mode" can automatically enter the parking mode as long as the vehicle is parked and turned off. The dash cam will trigger the video recorder when it detects object movement or collision and vibration, and the 890D is the first Mio model that can independently detect both the front and rear cameras. The front and rear cameras will record 4 seconds before the accident point + 16 seconds after the accident. The 20-second video allows you to clearly understand what happened. However, if you want to use the smart three-in-one parking mode, you need to purchase an external power cable, and the resolution will be automatically adjusted to 1080p/30fps when using the parking mode.

Actual recording screen

The following is the actual video recording status of the Mio MiVue 890D under different conditions such as daytime (sunny/cloudy) and nighttime for your reference. The videos recorded this time are all shot at the highest quality of the front and rear cameras (1440P/30fps), The EV exposure compensation value is all 0; in addition, the front glass of the test car is also cleaned, and the light transmittance of the front and rear glass heat insulation paper is 70% and 35% respectively. Quality adjusted to the highest. For consumers who only need the front lens and want the ultimate video quality, they can also consider the latest single-lens model MiVue 887 launched by Mio in August this year. The biggest feature is that it provides 4K image quality (3840 x 2160 / 30fps), and has twice the photosensitive area than the general photosensitive element (1/3", 8 million pixels), bringing clearer and sharper picture quality and color, and improving the brightness of night shooting; in addition, MiVue 887 It is also Mio's first model equipped with the third-generation "safety warning six-in-one". Other functions, including intelligent parking mode and writing in seconds, are also readily available.
