In the modern age where digital life is more and more developed, people are more closely integrated with various electronic products than imagined, and the popularization of driving recorders has also made it easier to clarify the responsibility of traffic accidents. The driving recorder for automobiles has integrated many high-tech technologies, including voice navigation, GPS satellite locator, and Google Map. The dazzling functions are always dazzling. So, what about the locomotive? At present, the products that can be selected on the market are not as diverse as those used in automobiles. This time, the little devil will share the trial experience of the new MiVue M300 locomotive driving recorder launched by Mio.

The tachograph used in motorcycles is not the same as the style used in automobiles. It can be roughly summarized into three key points. The first is the problem of power supply, the second is the fixed position and method of the recorder, and the third is the waterproofness of the casing. , these are the problems that most riders may encounter when they want to install the tachograph for motorcycles. Let's take a look at the performance of the Mio Little King Kong MiVue M300!

Considering that it may be possible to exchange and ride different motorcycles to go out, this time I used the method of fixing on the helmet to do the test.

●Unpacking

The packaging of Mio Little King Kong MiVue M300 is particularly famous as AO4800B locomotive driving recorder. The right side of the box also indicates that it can be used for general locomotives, heavy locomotives, bicycles, outdoor sports, etc. It can be applied under the Mio design The range is still wide, depending on how the user uses it.

The back of the box is marked with product specifications, random accessories list, ten product features, M300 waterproof level is IPX8, H.264 image compression technology, full HD 1080P picture quality, operation vibration prompt, dual-head waterproof car charging source, built-in 650mAh Lithium battery, 120-degree wide-angle lens, built-in camera function, quick disassembly and assembly of fixed base, loop video function. Several features are obvious at a glance.

●Accessories introduction

There are four types of fixed bases that can be used. For locomotive users, the vibration of the vehicle is greater than that of the car, and the body will tilt when the locomotive turns, so the fixing method and position of the driving recorder are very important. Whether the vibration of the recording screen can be minimized is a test of the installer's skills and experience.

The ring-shaped mainframe fixing bracket has a rubber bushing inside to prevent the mainframe from shaking. After the ring bracket switch on the side is turned off, the tightness of the screws can also be adjusted manually. In the experience of this actual measurement, even if the speed of the vehicle is pulled in the racing field Up to 140 kilometers, the ring support is still very firm and has not loosened. (The state of being mounted on the helmet)

The lower base of the ring-shaped fixing bracket has an installation direction, and can be smoothly put into the frame fixing base according to the direction of the arrow.

The assembly of the base is very simple, and it does not require much effort. When you hear a "click", you can confirm that the assembly is complete. Usually, I am used to pulling it back and forth twice to confirm that the base is fully clamped.

When the composition is completed, the base is not large, and the length, width and height of the host are 101.76 x 39.3 x 22.71mm. You can roughly compare the relative size.

There is also a spherical structure under the ring-shaped fixing bracket to adjust the lens angle of the recorder, and the angle that can be adjusted up and down is approximately between 15 and 20 degrees.

The left and right tilting adjustment angles are between 5 and 10 degrees. The user can adjust the level of the lens screen according to the installation position. This is a very important part of the locomotive. The locomotive can be fixed in limited space and cannot be like It is easy to adjust the position of the lens like a car. Even if it is installed on a helmet, it is necessary to use the spherical structure to fine-tune the angle of the lens in order to optimize the recorded picture.

There is a tenon on the fixed base that can be pressed. After pressing down, the ring bracket can be separated from the base. The new tenon will be tighter and may require a little effort.

Another base, this is a type that can be locked with screws, but since the original factory does not indicate the specifications, the screw specifications may need to be checked before knowing.

This one is a fixed base using 3M double-sided foam glue, because the author has already taken it and fixed it on the safety helmet, so I can only show you how it has been used.

The base of the drawstring style, as long as the things that can fit in, are almost tied tightly.

Put it on the water bottle for demonstration, and tighten the ring tightly to fix it.

There is also a tenon to fix the strap elastically. This fixed base should be used in outdoor sports. Because of the large vibration, motorcycles may not be suitable.

Waterproof car charging cable set, also equipped with AC charger and USB transmission cable.

The waterproof car charger set includes a waterproof cover and a USB connector.

After plugging in the USB connector and then locking the waterproof cover, assembly is quick and easy.

In the completed state, the car charger can be used even if the recorder is installed outdoors, which is quite practical. (Of course only for cars with car chargers)

It is a general traditional car charger plug with a power supply specification of 5V/1A.

It is also equipped with a traditional USB cable set and a USB car charger adapter. In fact, in my opinion, it may be more convenient to use USB charging. Now there are quite a few USB adapter kits for motorcycles that can be modified by themselves, and the power supply problem is easier to solve. would be too big of a problem.

A lanyard, one of the accessories, hangs on the wrist to prevent it from falling off when holding the dash cam.

●Functions of each department

First we see the core of the dash cam, the lens. Using CMOS sensor, 5 million pixel lens, resolution of 1920 x 1080P (Full HD), 30fps, the specifications meet modern needs, the actual recorded images will be shared with you later.

The waterproof cover is opened at the back of the recorder, and the Mni SD slot, USB port, indicator number, and recording mode switch button are all here.

Let's look a little more clearly, from top to bottom and from left to right are the memory card slot, charging indicator, USB jack, reset button, and video/photo recording mode switching button. When placing the memory card, remember to pay attention to the direction of the memory card, and put it in the slot until the memory card is fixed. When you want to take it out, do the reverse operation. Press the memory card lightly to release the card and take it out.

When using MicroSD memory card, the original factory recommends to use Class 6 with a capacity of 8GB or above. The maximum memory card size corresponds to 32GB, and 8GB can record about 100 minutes, and so on. For general commuting, 8GB of memory is enough. The recorder is a loop type of recording. When the remaining space of the memory card is insufficient, the recorder will cover the images with the oldest time in sequence and temporarily archive them.

There are two buttons on the outside of the recorder. The upper left is the power button. Press the power button for 2 seconds to turn it on. The blue indicator light is the power light. Press the shutter button (orange button) and release it, the status indicator will light up red, which means recording (photo or video) starts. Another feature of the M300 is that the main unit will have a vibrating prompt during operation to remind the user of the current mode, which is easy to operate, especially when it is installed on a helmet, the number of vibrations can be used to judge the status of the recorder. After the recorder vibrates three times, it will automatically start recording in a loop, and continuous recording will save a short video every five minutes without interrupting the recording. If you want to stop continuous recording in the middle, press the shutter button and release it, the recorder will vibrate once, which means that the recording has ended.

Charging light, green means charging, when the light is off, charging is complete. If the red light is flashing, you should pay special attention. It may be that the memory card is not inserted properly after the power is turned on, and the memory card needs to be reinstalled after the power is turned off.

Regarding the power supply, the author mentioned at the beginning that the most fearful thing about installing a driving recorder on a motorcycle is the power supply problem. What if there is no car charger and USB socket? It doesn't matter that the M300 can be charged with a 5V/1A power bank, which is quite convenient. In the experience of this trial, the author tested a completely dead recorder with a 5V/1A mobile power supply, and recorded another 15 minutes after charging for about half an hour. The built-in battery capacity is 650mAh lithium battery. After this actual measurement, it can be used for about 1.5~2 hours. If the internal power supply is used, it can only be used for general commuting records, and an external power supply is required for long-distance travel. According to Mio officials, such battery specifications are designed mainly based on volume and usage requirements.

If it is installed on a vehicle equipped with a car charger, it is the most perfect. Using a waterproof car charger can solve the problem of long-term power supply. Now most of the yellow cards are listed as standard, and it is just right to use a driving recorder.

For the waterproof performance, the waterproof rating of the casing is IPX8. After continuous diving test, it can withstand the waterproof test of 3 meters and 60 minutes underwater. It is installed outside the vehicle and exposed to heavy wind and rain without worrying too much.

The button parts are also waterproof, and there is no problem in the operation of the machine in bad weather.

●Actual installation photo

Attached are a few photos of the actual mounting on the hat.

On the left side, the switch of the ring-shaped fixing frame is very firm. In fact, the stability of the bracket is no problem when riding at a speed of 140 kilometers per hour at the racetrack.

On the right side, the tenon at the back of the base is to control the engagement of the ring bracket and the base, which is very convenient for quick disassembly and assembly.

In the front, the lens has a 120-degree wide-angle field of view. Basically, in addition to the lane you ride on, there are ways to record the outside scenes on both sides.

At the rear, after the waterproof protective cover on the back of the host is covered, the internal buttons and memory cards are well protected. However, it is quite troublesome to switch the photography mode, and you need to open the cover to access the switch button.

●Measured videos and photos

Attached are some videos and photos for your reference

◆Mio MiVue M300 recording screen

Shot by Mio MiVue M300_Riding on the elevated road @Mobile01

In broad daylight, the 1080P picture quality is very comfortable to watch, and the picture is very clear. However, because there is no way to preview the picture first, the angle of the video camera when riding the elevated road section is low. It is suggested that you must confirm the picture and adjust it at the same time when installing, so as to record the most ideal driving picture.

Shot by Mio MiVue M300_Riding at night @Mobile01

In general road driving pictures at night, the picture grains are slightly larger in places where the light source is insufficient. Judging from the lens specification of 1920 x 1080P (Full HD) and 30fps, the night picture is smooth and not stuck.

◆Mio MiVue M300 to take pictures

It was taken when testing tires at Longtan Lohas Circuit. It was a little cloudy, but the light source was enough. In this case, the picture quality of the photos is barely passable.

The quality of night photos is not ideal, and it may be that the lens is slightly shaken and the picture is not good. However, after trying to take many photos, this is the one that can be seen in night photos. When the light source is insufficient, the M300 still has room to improve the quality of the photos.

In the elevator with sufficient light source, the picture taken by the author to the elevator mirror is much better, which proves that light is indeed one of the key elements of photo quality.

●Software introduction, trial summary

◆MiVue Manager

Mio's original factory provides video management software, which can be sorted and archived according to time and date. The screen is as shown above, the largest area on the upper left is the video window, and the upper right is the calendar. You can click and select the video you want to find according to the time. There are three types of video categories: event, general, and parking pictures. The lower right side is the file list, with file name, date and time. And some computers may not be able to play the files of the recorder due to the problem of video encoding. It is recommended to install the original software to solve this problem. It is a playback program in itself.

Although this driving recorder is not particularly powerful, it has provided quite enough recording functions, and there are records and protections.

Several key points of the locomotive dash cam mentioned by the author: power supply, fixing method, waterproofness, Mio MiVue M300 can be considered to be achieved, the quality of installation is up to the installer, and more adjustments and more attempts at the lens angle can be achieved. It's the only way, it takes a little patience and time.

●To reconcile the use experience!

◆Recorder installation:

After getting along with MiVue Manager in the past few days, the way to install on the helmet is the fastest and easiest to adjust, and it does not need to be moved anywhere on the motorcycle, and it is also convenient to restore in the future. The picture should be the most stable, the most standard viewing angle, or it needs to be fixed on the frame, but the situation where the recorder and the vehicle resonate is the first problem that needs to be overcome. The quick-release base tenon design is great! It can be easily removed when leaving the locomotive, no need to consider the problem of anti-theft.

◆Machine operation:

The operation method is very simple, especially the vibration prompt is very good. I installed it on the safety helmet, and I only need to pay attention to the number of vibrations to know the current operation status. It is a little more troublesome to open the waterproof protective cover on the back of the main unit when switching the photo/photography mode, but the design is helpless for the appearance of the waterproof function.

◆Power supply:

The performance of the 650mAh lithium battery is fairly good. Generally, the endurance for urban commuting is sufficient, and it can supply 90 to 120 minutes. To support long-distance travel, it can also be solved by connecting to an external power supply. The specially designed waterproof car charging cable set is a very thoughtful design. It is a kit set tailored for motorcycle users.

●Trial summary

The MiVue M300 image quality is fine for me personally, and I have no problem recording some commuter traffic profiles. In the case of sufficient light source, the picture quality performance is still normal, and when the light source is insufficient, it is not satisfactory, but it is very useful to be able to immediately come in handy when there is some emergency situation that urgently needs to take pictures. As for the installation position, it should be one of the difficulties encountered by most people. The vibration of motorcycles is much bigger than that of cars. If it is not installed properly, the lens will vibrate and the picture will basically be unusable. This is especially necessary. part of attention. If a suction cup-type structure can be added to the part of the fixed base, the difficulty in vehicle installation may be reduced. Based on the premise of not wanting to change the motorcycle, I will still choose to fix the dash cam on the helmet in the future. For the power supply part, as long as the vehicle power supply problem is overcome, no matter how long the distance is. Mio has also launched the IPX8 waterproof design in good faith, and the weather resistance of the fuselage also has a certain level. This is a rare motorcycle-specific driving recorder launched by Mio. The performance of the MiVue M300 is in line with expectations, and it is worth choosing as one of the motorcycle driving recorders.

Finally, I attach the photos of the cycling during the test, and the approximate appearance of the cycling recorder installed in the helmet.
