As a private car owner, I have been trying to find a driving recorder with excellent recording performance and effect. The video effect can be better during the day and night, and it must be glass lens without missing seconds. From the previous recognition of brands and chips to the current emphasis on practical effects, the focus has also shifted from traditional tachographs to intelligent tachographs. For the moment, the intelligent tachograph in my eyes, in addition to the functions of the traditional tachograph, can also connect to the network, have the Bluetooth function, and can connect to the mobile phone to operate and control through the APP.

The staring and shooting mini2 is an intelligent DASH CAM with Hi3516D platform, supporting 1440P ultra-high definition video recording, 140 ° wide-angle shooting, and one click capture and video recording.

The exterior packaging of the mini2 is a bit ordinary, but the interior packaging is slightly fashionable. The package contains a 2.4GHz wireless remote control camera button for capturing, a mini2 host (with a 3M adhesive rotatable bracket), 3.5m long wire, clips for fixing wiring, dual USB output port car charger and two small blue crowbars for auxiliary wiring.

A 16G Class10 Netac Ronco TF card comes with the package. In terms of capacity and read-write speed, it can meet the actual recording needs with a recorder.

The body of the staring and shooting mini2 is cylindrical in design, without a screen. It needs to be connected to mobile phones, tablets and other devices through APP for viewing, setting and other operations. The volume is 87mm * 35mm * 43.5mm, the bracket is connected to the body as a whole, and the charging interface is designed on the bracket. The bracket is not easy to remove, but can rotate 270 degrees. Instead of using a suction cup design, 3M glue is pasted on the front windshield. In comparison, I prefer the suction cup base design, which is more convenient for installation and disassembly.

Six sets of glass lenses, one infrared filter and F1.8 aperture are used for staring at the mini2 lens. The angle of the picture is 110 ° horizontally and 140 ° diagonally. At present, the ultra wide angle advertised by general merchants in the market refers to the diagonal. The main control chip of the staring and shooting mini2 does not choose the common Ambarella, Novatek, Allwinner, etc., but Huawei Hi3516D, which supports H.264 encoding and 1440P ultra-high definition video encoding. I have no absolute belief in the choice of chips, because the recording effect of the same chip in different manufacturers' products is very different. The staring mini2 image chip is an Omnivision OV4689 4 megapixel CMOS image sensor, which supports WDR wide dynamic technology. This is also the focus of staring at the mini2. Like other intelligent tachographs, the staring and shooting mini2 has a built-in three-axis acceleration sensor G-Sensor, which supports automatic crash locking, but does not have a built-in battery. Instead, it relies on a built-in capacitor to support the last video recording after power failure.

The power interface of the staring and shooting mini2 is a popular micro USB interface. On the same side of the interface is designed a reset hole for restarting and resetting the device. The TF card interface for storing videos is also on the same side as the reset hole. The better design is that one end of the card has a cover to protect the inside. At the other end of the fuselage is a 1W power horn. MIC is designed on the cylindrical fuselage, and the status indicator is designed on the edge of the fuselage.

Stare at the effect picture of the normal recording of mini2 when it is powered on. If the TF card is not inserted, the indicator will flash continuously.

In terms of peripheral accessories, the battery charger of the mini2 adopts the design of 2.1A and 1A interfaces, so there is no need to worry about the trouble of charging the mobile phone when the charging interface is occupied. The body is more exquisite and beautiful in workmanship.

The one button snapshot remote control used with the staring and shooting mini2 can be pasted on the steering wheel through the provided double-sided tape, or can be carried with you. The remote control is powered by a 3V button battery, not a rechargeable lithium battery.

However, the plastic crowbar used for wiring is a little small and not very strong. A thick crowbar can be provided.

Since the staring and shooting mini2 adopts the 3M pasting and fixing method, the installation should first find the appropriate position on the perspective and then install it. It needs to use the mobile phone APP to confirm the position. It is installed in front of the rear-view mirror at your choice, which will not affect the line of sight. The white one next to it is the Xplore C+intelligent DASH CAM. The bracket has a PTZ design, which can be installed randomly and then adjusted. However, the advantage of the stick design over the suction cup design is that it is not easy to fall in winter.

Because some users will use the parking monitoring function, it is necessary to ensure continuous input in power supply. Most people may get used to connecting to the car battery by matching the step-down cable, which is a little troublesome. In contrast, it will be more convenient to directly purchase the dedicated reading light line dedicated to the staring and shooting mini2 on a treasure, and users who need it can search by themselves. As for parking monitoring, there are some limitations in personal perception of starting recording solely by the vibration of the DASH CAM. It is better to automatically start recording with infrared detection of object movement, but it is not 100% effective, for example, the side of the vehicle is hit or scratched artificially.

The APP corresponding to the staring and shooting tachograph is staring and shooting, which integrates the "on the road" user community. You can view the video or picture content shared by netizens here. Whether it is beautiful pictures or violation reports, the most meaningful thing to learn is various violations or traffic accidents. You can communicate or comment with others, which is very meaningful for novice drivers. You can also share through the app.

The connection between the staring and shooting mini2 and the mobile phone is via wifi mode. After the connection is successful, the app terminal can be used for capturing, firmware upgrading and other operations. The link with the recorder is relatively simple and convenient, because it can be added directly without manually entering the password after finding it. It is no longer necessary to find the preset password and manually enter it, and it is not necessary to enter the password again after reconnecting after disconnection.

After the connection is successful, you can see the preview screen, and the related settings page will also enter the preview screen. Parking monitoring is enabled by default, but I suggest setting the collision sensitivity to the highest, which will be more practical.

Another commendable feature of the setting function of the staring and shooting mini2 is the firmware upgrade, which can be seen as supporting OTA upgrade. Although it is also necessary to upload the upgrade package, the APP has been automatically downloaded to the mobile terminal. As long as it is connected to the device and the user confirms the upgrade, it will automatically upload to complete the entire upgrade operation. Compared with other intelligent tachographs, this is a very user-friendly place to do.

As a tachograph, I care not only about hardware configuration, image quality, resolution and viewing angle, but also about continuous recording stability and second leakage.

The stability of video recording is the basic condition for normal operation, which is related to obtaining the desired video part. Here, the method of three consecutive recordings for five hours is selected for detection (with 32G Samsung original TF card). As long as the video can be recognized by the player and played normally, it can be considered as passed. From the detection of the actual recorded video, the problem that the video could not be played once occurred in the first continuous recording of the dash cam mini2, as shown in the following figure for the movie without thumbnail. The videos recorded again after formatting can be played normally. The most worrying problem is that the fuselage is hot, but after the whole test, the fuselage is hot but not so hot that it affects the video recording.

The staring and shooting mini2 uses the mp4 format. The default video length is 3 minutes, and the resolution is really 2560 * 1440, which is consistent with the publicity. But the video frame rate is locked at 25 fps, not 30 fps (generally 29.9 fps). The sound collection is sensitive and the sound quality is clear.

For the tachograph, the second leakage should not exist. Whether by overlapping the previous video for one second or making seamless recording perfectly, the loss of one second may cause insufficient evidence or omission. From the comparison between the last frame of the previous video and the first frame of the next video, it can be seen that the time is basically the same, and it can be considered that there is no error.

For the capture function, the good thing that the staring, staring and shooting mini2 does is that it is directly downloaded and saved to the phone by default after the mobile terminal operation. You can turn off this function in the settings. APP can only capture (taking pictures is associated with 10 second video), but it does not support manual video recording, nor can it directly download a single video file recorded in the card. If you need to view the video, just drag and drop the progress bar below. However, there is no function to cut movies in the vertical mode. Only in the horizontal mode can you cut and download movies.

In the measurement of horizontal angle, a simple measurement is carried out. The length of the horizontal actually displayed ruler is about 2090px, and the horizontal distance from the lens to the desktop is about 780px, which is converted into an angle of about 106 degrees, with a small error from the 110 degrees advertised.

Take a look at the actual video effect. There is no problem with the display during the day. The main difference is in the early morning, dusk and evening. First, let's look at the performance in the daytime. The following pictures are self recorded video clips of normal driving at different speeds, which can clearly see the surrounding license plate numbers. However, when the speed is fast, the recorded video screenshots will be affected, for example, the third one can barely be identified. The distortion of the picture is not very serious (refer to the upright bar on the left side of the first picture),

Let's look at the effect at night. There is nothing to be impressed with, because the license plates of vehicles traveling in the same direction can not be clearly recognized even if there are lights. You can see the surrounding license plates clearly when waiting for vehicles at the intersection. The signs with lights at night are basically blurry, which can be vaguely recognized. But it is better than Xplore in light processing and color.

Video capture during actual driving.

Personally, it is a brave attempt to adopt HiSilicon chips for the staring, staring and shooting mini2, and it is also a brave attempt for users who want to experience different chips. On the whole, the surprise of staring at the mini2 in detail experience is far greater than the expected night display effect, but it is better than the Xplore, which is also an intelligent DASH CAM. As it supports parking monitoring function, it is recommended to add infrared detection part, which can automatically start the recorder and save the video when there are objects or people passing by.

The user experience of the mini2 is better, whether it is connection settings or firmware upgrades. The advantage of 1440P UHD video recording is that it is better than similar 1080P DASH CAM in the picture during the day with sufficient light. There is no exaggeration in the visual angle. The supported WDR is enabled by default, which is extremely useful in the scene where the light changes obviously, especially when leaving the culvert and bridge opening. The sound recording effect is worth paying attention to because the pickup effect is excellent, and the sound inside and outside the car can be recorded clearly. For novices, the function of APP community is not only to share recorded videos and pictures, but also to update and upload illegal or accident videos by other users.
