How to choose the driving recorder in 2020? Old drivers share 12 purchasing experience.
Let's briefly talk about how to buy a driving recorder and the matters needing attention in the purchase.
1. Do I need to look at the brand to buy a driving recorder?
Recorder is a complex electronic product, which needs to run in the car at high temperature all the year round and vibrate strongly. The average level of repair rate is as high as 3 ~ 5%, and the repair rate of good products is close to 1%. When you really encounter problems, the after-sales service of a good brand will be more secure, so choosing a recording pen must depend on the brand. What are the mainstream brands on the market at present? Let's summarize the best-selling styles on the market first. There are 38 VCRs in total, and there are 13 brands in total.
13 brands include: 360, Hewlett-Packard, Stalking, Ling Du, Hikvision, Jiedu, PAPAGO, 70 Mai, Ren exing, Xiaomi, Yunlu, Kouhongji and Xingkewei. The more common brands in China are 360 and Ling Du, but the products of these two brands are of average quality and are not recommended. Among them, 360 is mainly burnt card, which can't resist high temperature. The problem of burning cards is still relatively common. Many people in the 360 official community spit out that they should avoid being exposed to high temperature for a long time in summer, otherwise the battery will bulge and burst.
Ling Du is mainly involved in parameter fraud, while some products in Ling Du are suspected of having false parameters. For example, the Ling Du V360, which is now sold online, is advertised as 4,800 W pixels, but the recorded video effect is extremely poor, and it is not as clear as 1080P, because the resolution does not represent the definition, and the resolution can be modified by software. In addition, the model of Ling Du V360 image sensor was not introduced by Sony. IMX335 sensor, is it really Sony? IMX335 sensor, the dynamic pixel is only 500W, not the advertised 800W, which is obviously suspected of false propaganda. Many products in Ling Du are virtual standard parameters.
Kou Hongji, Xingkewei and Yunlu are relatively unfamiliar, because these three brands are mainly engaged in foreign markets and their domestic prices are relatively high. The products are all high-end routes, and the quality control is better. Repair rate is around 1%. Personally, I suggest giving priority to Kou Hongji and Xing Kewei. Compared with other brands, the product quality is really good, and the price is around 1000 yuan. If you think the price is too high, you can consider choosing Yunlu, and the product price is around 600 yuan. The probability of these brands buying return machines is relatively small, mainly due to good quality control, because many people have considered it for a long time before choosing, and general machines will not be returned without quality problems. But the price is low, the product quality control is not good, the machine will have some minor problems, and many people will return it. Merchants who return goods will definitely repackage them and sell them again. It's normal not to feel brand-new, so it depends on luck. The product is fine. If you use 1-2 months, there will be a problem, and you can't return it then. If the after-sales service is poor, it is hard to say whether the merchants will ignore you.
2. The definition of the recorder mainly depends on the main control chip and the photosensitive chip.
The clarity and night vision effect of the recorder need not only hardware, but also software debugging, among which image processing chip+image sensor+lens constitute the core of the recorder, plus software debugging. Many people know about chips, but little about lenses. If the chip is the same as the image sensor, but the lens is different, it will have a great influence on the definition and night vision effect. Lens is an important factor affecting the amount of light entering, which is composed of multilayer lenses. The main factors affecting its quality are materials and coatings. Common means of bad manufacturers: there is no difference between chips and image sensors, but the lenses used are weighed and have no quality at all. But in fact, the lens has a great influence on the clarity and night vision effect.
3, the lens glass material, the effect does not look much different.
The materials of lenses are divided into glass (G) and asphalt (P). 4G lens /6G lens represents 4 layers of all-glass /6 layers of all-glass, and 2G2P lens refers to two glasses and two trees. At present, most brands on the market use G4-G6 all-glass lenses, and G6 will include an infrared filter called 6+ 1? * * * Seven movies are all lies. Compared with glass lenses, resin lenses are easy to scratch, and will be deformed and cracked when exposed to high temperature. Responsible manufacturers generally do not use them.
Secondly, in order to improve the wide-angle and imaging quality, the recorder should use multi-layer lenses. Both glass lenses and resin lenses have certain shading effects, with each glass shading 8% and resin about 10%. Multilayer lenses can also make the incident light loss as high as 30% to 40%. In order to reduce the reflection and improve the light transmittance of the lens, the advanced optical lens coated with multilayer antireflection film is used in the high-end driving recorder. It is reported that the best coating technology in Japan can transmit 99.98% light. For example, some high-end driving recorders on the market now use advanced optical lenses coated with multilayer antireflection films, while low-quality lenses without coating are easy to be "seen through" and the interior of the lenses is "unobstructed". The lens coated with multilayer antireflection film is light green or deep purple. Let's take the lens of Yunlu R 1X as an example to see the effect of multilayer antireflection film.
4. Why can't I see the license plate clearly when driving?
Whether the license plate can be seen clearly is affected by the following factors: relative speed, relative distance, road smoothness, lighting conditions, shooting angle and so on. If the speed is too fast, even if the light is sufficient, the license plate can't be seen clearly, which is normal. Because the dynamic effect is mainly determined by the frame rate, such as shooting balloon explosion, ordinary cameras can't see the specific process, while high-speed cameras can, which is the reason. Usually, the driving recorder is stationary or at low speed, the lighting conditions are guaranteed, the distance is not too far, and there is no problem in seeing the license plate. The speed is different, the distance is different, and the lighting conditions are different. It is relative to look at the license plate, so there is no need to struggle. Video recorders from regular manufacturers can clearly capture relatively static objects within 5 meters from the front of the car. There is no pressure and anti-collision porcelain is enough (because continuous video recording will always capture a relatively moving license plate).
5. Is the pixel and resolution as high as possible?
In fact, the driving recorder products pay attention to practicality and durability, and not all parameters are as high as possible. Like many businesses now, advertising pixels are12 million pixels, 1800W pixels, 2400W pixels? This is completely misleading, because what they claim may be a static effect, and all the driving pictures are dynamic, which can't reach this pixel at all. Canon SLR is only 1800W, and it is top-notch and needs tens of thousands of pieces. A tape recorder for several hundred dollars is impossible. It is absolutely impossible to spend hundreds of dollars to buy tens of thousands of professional cameras to achieve results.
The dynamic pixel of the video recorder can meet the demand when it reaches 500W, and the static shooting is completely sufficient. Don't blindly believe that the higher the chip model, the better. Too high resolution will greatly reduce the service life of the memory card and shorten the video recording time of each card. In addition, if the resolution is too high, the average amount of light entering each pixel will be reduced, and the night vision effect will be worse, which is not worth the candle. For example, when we watch 720p movies on TV, it is already very clear. Even if it rises to the source of 1080p, the difference in clarity is not obvious. However, the data volume of 1080p is twice that of 720p, and the data volume of 1296p is 0.4 times that of 1080p, that is, the same TF card. At this moment, not only the video recording time is reduced by 30%, but also the repeated reading and writing times of the card are greatly increased, and the service life is shortened. Similarly, a movie with 24 frames per second is already very clear and smooth. If the number of frames is increased from 30 to 60, it will also reduce the recording time and shorten the life of the card. Driving recorder products pay attention to practicality and durability, and not all parameters are as high as possible.
6. Why is there a crash or a stuck machine?
The main reasons for the crash and jam depend on the working hours. The longer the working time, the greater the heating degree and load of the motherboard, and the higher the probability of crash. If it is only used for daily commuting, it will basically not crash (except cottage chips). At present, all major brands will crash. The most common case of crash is that the machine works continuously for dozens of hours and repeatedly reads and writes the memory card. After a long time, the memory card will be damaged, and the reading and writing speed can't keep up, resulting in a crash and jamming.
7. Is the angle as wide as possible?
The wider the wide angle, the wider the scope of recordable evidence. In order to maximize the recording range and facilitate evidence collection, the recorder should use a wide-angle lens, but the edges will definitely be deformed. For example, the wide-angle recorder of 160 degrees on the market at present will definitely be deformed on both sides. If the deformation is to be removed, the edge part will be cut off during the image processing, resulting in the loss of effective information. In other words, the edge of the image is neat, indicating that the wide angle of the recorder is small, and the wide angle of the lens that will not be deformed is less than 120 degrees.
8. What style should the driving recorder choose?
Personally, it is recommended to install it on the front windshield. Generally, this kind is installed with 3M glue or sucker, and the styles are divided into screen and non-screen. It is recommended to choose the one with a screen, because the recorder is in the car, which should be resistant to high temperature in summer and freeze in winter. I wonder if it will be useful. Although there is an indicator light, you don't pay attention every time. At least you can look at the screen.
However, the disadvantages of rearview mirror style are jitter (jitter of rearview mirror recorder) and dark mirror surface (dark rearview mirror recorder), which will seriously affect the observation of the rear of the vehicle. In addition, it is necessary to confirm whether the anti-glare function is affected and whether the mirror used is safety glass; When they use the car, they should also consider the trouble of adjusting the lens angle of the recorder at the same time every time they adjust the rearview mirror. It's best not to use streaming media. Although it has anti-glare function, the lens will shake after the headlights are lit at night. If the original car comes with an electronic anti-glare rearview mirror, don't install a recorder with a streaming rearview mirror.
9. How to choose the night vision effect?
The night vision effect is mainly related to the image sensor and also depends on the application scenario. Generally refers to night vision, which is scientifically called low illumination. Low-light photography means that clear images can still be taken under low-light conditions. Illuminance is the luminous flux received per unit area. Simply put, what we usually say is whether the desktop is bright enough, that is, the illumination. The illumination in home and office is generally between100 and 300 lux, and the street lighting is about 5 lux.
The image sensor of the driving recorder is 1/3 inches, so the larger the total number of pixels, the smaller the single pixel. Of course, it is necessary to cooperate with high-quality multilayer coated lenses to fully display the night vision effect.
Sony models commonly used in the market mainly include SONY323, SONY307 and SONY335.
SONY323: Sony's earlier sensor video has 2 million pixels, that is, the maximum pixel is 1920* 1080P. Good effect during the day, average effect at night, no night vision function. Some models are still in use in the market, but it is estimated that they will be eliminated in the future.
SONY307: The video pixel is also 2 million, and the maximum is 1920* 1080P. With the function of low-light-level night vision, it is currently adopted by many recorder brands. Its performance is better than that of Bisogni 323, and the effect is quite satisfactory.
SONY335: The video is 5 million pixels, with excellent daytime effect and excellent imaging at night. With starlight night vision effect, the overall effect of Bisogni 307 is excellent. At present, in the driving recorder, there are only a handful of sensors that can achieve 2K high definition like SONY335, and the imaging effect is very good.
On the other hand, the night vision effect is good, and the F value of the aperture is small, but too small F value can easily lead to excessive violence during the day. The recorder should take into account the influence of day and night. If the aperture f value is small, the depth of field will be shortened, and it is not easy to see the distant license plate. At present, F= 1.6 is moderate, and F 1.6 is the golden light input of the burner. If the f value is too small, the night vision will be too dim to see clearly. If F 1.2- 1.4 is too large, the night vision exposure will be too full, and the license plate will easily reflect light at night.
10. Is it better to use a battery or a capacitor for the driving recorder?
This is a problem that many people have been struggling with in recent years. The battery or capacitor is used to continue to supply power to the video recorder after power failure, save the last video and supply power to the built-in clock. At present, the manufacturers are still 50/50. If the capacitors are all good, there will be no battery manufacturer.
The purchase price of general capacitors ranges from a few cents to several yuan. A tape recorder with 2-3 Rafah capacitors has the advantages of high temperature resistance, generally reaching 85 degrees, and fast charging. These manufacturers will say that it is safer to sell without batteries in packaging or product promotion. However, once the capacitor is in Explosicum, it is likely to seriously affect the corrosion of the recorder motherboard and cause irreversible damage.
The advantages of the battery, battery life will be guaranteed. Reliability is better than that of capacitor. Generally, the motherboard will not be corroded, and it will not be turned on for the second time because of the power change of the car. At present, manufacturers of video recorders often choose lithium-ion polymer batteries. The first is high energy density, small volume, and the capacity is generally above 200 -500 mA. The second is high temperature resistance. This kind of battery can reach 85 degrees, and it won't bulge or explode.
1 1. Do you need the WDR function?
Why is the recording effect of a machine completely different in different cars, different places and different lights? The main reason is the relationship between WDR and HDR. Among them, WDR is the abbreviation of Guangdong. Simply put, wide motion means that both the particularly bright part and the particularly dark part of the scene can be seen clearly at the same time. Wide dynamic range is the ratio of the brightest brightness signal value that an image can distinguish to the darkest brightness signal value that can be distinguished. Generally, in the case of strong light or relatively low brightness such as backlight, the camera image will appear particularly bright or dark. Bright areas are caused by overexposure, while dark images are caused by underexposure, which will seriously affect video clarity and quality.
12, how to choose the memory card size?
If the average daily driving time is about 90 minutes, 32G is enough, and a 32G card can record 320 minutes of full HD video, which can be saved for more than three days, which is enough for most people. If monitoring is needed for a long time, it is recommended to use a 256G memory card, which can be stored for a longer time, but there are still a few brands that can support 256G in the market. The reliability and service life of the memory card are very important, and it needs class 10, otherwise it can't keep up with the reading and writing speed of HD video. SanDisk or Samsung high-speed card is recommended (it can work at -25 degrees to 85 degrees, adapt to the working environment of the recorder, 32G can record 5000 hours, and its service life is almost two years).
Introduction of driving recorder types and comparison of advantages and disadvantages
Now I have basically listed all the styles on the market and summarized their advantages and disadvantages. Personally, I don't recommend you to use the rearview mirror, because the original rearview mirror is nearsighted and it will be safer to drive. It's best not to use streaming media. Although it has anti-glare function, the lens will shake after the headlights are lit at night. If the original car comes with an electronic anti-glare rearview mirror, don't install a recorder with a streaming rearview mirror.
What styles are recommended for driving recorder in 2020?
Firstly, we divide the above 38 machines into four price ranges according to the market price: below 300 yuan, 300-600 yuan, 600-900 yuan and above 900 yuan. We recommend two models for different price ranges.
At present, the highest price of recorders on the market is more than 2000 yuan, and a penny is worth a penny. Expensive things can't be bad. Of course, we don't want to change the tape recorder frequently. It's better to use it for several years. Electronic products are updated quickly, expensive hardware configurations are relatively new, and old hardware configurations may be eliminated next year. In addition, the new hardware has more comprehensive functions and better clarity. Kou Hongji DR900S and Xingkewei U 1000 are recommended for recorders above 900 yuan.
Kou Hongji DR900S driving recorder, recommended index: ★★★★★☆.
The main control chip and image sensor are unknown.
Camera pixels: front lens 800W, rear lens 200 w.
Aperture of main lens: F2.0
Image resolution: 2 160P.
Maximum supported memory: 128G
Installation method: 3M glue
24-hour parking monitoring: step-down line
Kou hongji DR900S supports double recording before and after. The front and rear lenses are installed with 3M glue, and the machine has no screen. The highlight is that it supports remote monitoring, video can be transmitted to the cloud, and the cloud service function is advanced. However, it is necessary to equip the car with mobile WIFI and purchase the cloud service function before it can be used. And Android phones can't easily get BlackVue's mobile phone application. Most domestic platforms don't have this APP. Need to climb over the wall, the APP is more troublesome.
Xing kewei? U 1000 driving recorder, recommended index: ★★★★★☆.
Image sensor: front lens Sony? IMX334, rear lens? Sony? IMX335
Camera pixels: front lens 800W, rear lens 200 w.
Aperture of main lens: F 1.6
Image resolution: 2 160P.
Maximum supported memory: 256G
Installation method: 3M glue
24-hour parking monitoring: step-down line
Kou hongji DR900S supports double recording before and after. The front and rear lenses are installed with 3M glue, and the machine has no screen. The highlight is that the machine integrates the road safety early warning system including lane departure early warning, front vehicle collision early warning and front vehicle start early warning. During driving, when the recorder detects a lane departure or is close to the vehicle in front, there will be a prompt sound to remind you. However, when using the front collision and lane departure function, the warning information is only available when the vehicle speed exceeds the value you set. For example, if the set value is 80km/h, there will be an early warning only when the vehicle speed exceeds 80km/h, which can play a certain early warning role, but there are still some errors.
If you think the prices of Kou Hongji and Xingkewei are too high, you can consider choosing the price range of 600-900 yuan, which can fully meet the daily needs. Below, I will screen out the recorders higher than those in 600 yuan for your reference. The main brand models are Ren E Bank P28, V 20 Yunlu R8S, R1X; ; Staring at the mini 5；; Among them, Ren E is a three-recording type, that is, there are three lenses, which can shoot the front, the heel and the inside of the car. The cost is high and the price is relatively high, while stare is new and the new model is expensive. If you want to choose 600-900 yuan, recommend Yunlu R 1X and mini5.
Yunlu R 1X driving recorder, recommended index: ★★★★★
Master control scheme: NT96670
Image sensor: front lens Sony? IMX335, rear lens? GC2053
Camera pixels: front lens 500W, rear lens 200 w.
Aperture of main lens: F 1.6
Image resolution: 2 160P.
Maximum supported memory: 256G
Screen size: 2.45 inches
Installation method: 3M glue
24-hour parking monitoring: OBD line and depressurization line.
Cloud road R 1X supports double recording before and after. The front and rear lenses are installed with 3M glue, and the single lens supports 4K resolution. If it is a double shot, the rear lens can rotate 360 degrees, and you can choose to shoot in the car or at the rear of the car. The highlight is to support gesture photography and OBD parking monitoring. Gesture photography is to wave a hand at the bottom of the machine, and both front and rear lenses can take pictures, which is much more convenient than button photography. OBD line parking monitoring supports dual mode, which can switch between vehicle power supply and constant power, and the interface is usually under the steering wheel. The advantage is that it can be installed by itself, and there is no need to disassemble things and connect the OBD line or other power cords. The disadvantage is that the cost of OBD is relatively high.
Staring at the mini5 driving recorder, the recommended index is ★★★☆☆.
Master control scheme: Huawei Hisilicon Hi3559? vanadic oxide
Image sensor: Sony? IMX4 15
Camera pixel: single lens 800W W w.
Aperture of main lens: F 1.6
Image resolution: 2 160P.
Maximum supported memory: built-in 64G
Installation method: 3M glue
24-hour parking monitoring: step-down line
The staring mini5 is a single lens and does not support dual lenses. Adopt Huawei Hi3559? With Sony's V200? IMX4 15 photosensitive chip, with built-in GPS module, can be matched with special 4G base, and supports remote positioning monitoring, voice photography and ADAS driving assistance functions. Staring at mini5 has many functions, but many functions are not very mature, such as remote monitoring and remote viewing. Another problem is that the machine is too hot.
The price range of tape recorder 300-600 yuan tends to be popular, and there are many brands to choose from. The main brands are 360, Stalking, Ling Du and Bahrain Dog. So I won't list the styles one by one. You can look directly at the picture below. What is the recommended Pawling dog S36 in this price range? 4K and Ling Du V260.
Lie on the dog S36? 4K driving recorder, recommended index: ★★★★★☆.
Master control scheme: Huawei Hisilicon Hi3559
Image sensor: Sony? IMX3 17

Aperture of main lens: F 1.6
Image resolution: 2 160P.
Maximum supported memory: 256G
Screen size: 3 inches
Installation method: 3M glue
24-hour parking monitoring: step-down line
Lie on the dog S36? 4K This is a single lens, does not support dual lenses, and uses Huawei Hi3559 main control chip and Sony? IMX3 17 photosensitive, 8 million video pixels, good definition. At the same time, it supports wifi function and 24-hour monitoring. Parking monitoring needs to install a step-down line. The monitoring mode can use the one-second frame mode, which effectively reduces the file size and consumes less power. But there is a problem that the voltage drops sharply when the vehicle is restarted, and the voltage of the step-down line with low-voltage protection is lower than 168.
Ling Du? V260 driving recorder, recommended index: ★★★☆☆.
The main control chip and image sensor are unknown.
Camera pixels: front lens 300W, rear lens 200 w.
Aperture of main lens: F 1.6
Image resolution: 1296P.
Maximum supported memory: 128G
Screen size: 3 inches
Installation method: 3M glue
24-hour parking monitoring: step-down line
Ling Du? V260 supports double recording before and after, 3M glue is installed in the front and rear lenses, and 4K resolution is supported in the single lens. In case of double recording, the front resolution is 1296P, and the back is 1080P, with a 3-inch OLED screen. The specific main control chip and photosensitive chip are not introduced in detail. Ling Du's products are low in price and wide in audience, but their stability is poor.
If the budget is not very high and you want to choose a cheap one, you can consider the one below 300 yuan. The main brand models are Ling Du F 12, F6 and V320. 70 miles midstream? D0 1、Midrive？ D05 staring at the mini? 2s and mini are all listed before 2020. You'd better think carefully about Ling Du's style. There is a lot of spit on the internet. Basically, there are various problems around 1 year, and the hardware configuration often appears virtual standard. Want to choose the following gaze mini recommended by 300 yuan? 2s and 70 mph Midrive? D0 1 .
Staring at the mini? 2s driving recorder, recommended index: ★★★☆☆
Master control scheme: Hayes Hi35 16D.
Image sensor: OV4689
Camera pixel: front lens 400W
Aperture of main lens: F 1.8
Image resolution: 1440P.
Maximum supported memory: 128G
Installation method: 3M glue
24-hour parking monitoring: step-down line
Staring at the mini? 2s is a single lens with 1440P resolution and no screen. Hisilicon Hi35 16D is a low-end chip. OV4689 has dynamic 400W pixels, but it does not support dark night vision, and the effect will be relatively poor when the night light is dark. According to this price and configuration, the cost performance is acceptable.
70 miles midstream? D0 1 driving recorder, recommended index: ★★★★☆☆.
Master control scheme: Mstar8336D.
Image sensor: SONY307
Camera pixel: 200W
Aperture of main lens: F2.2
Image resolution: 1080P.
Maximum supported memory: 64G
Installation method: 3M glue
24-hour parking monitoring: step-down line
70 miles midstream? D0 1 uses Mstar8336D main control chip and SONY307 photosensitive chip, and the dynamic pixel is only 200W W, and the effect can only be said to be average. Keep an eye on the mini during the day, okay? 2s, but SONY307 supports low-light-level night vision, and OV4689 does not. At night, no lights, 70 miles per hour Midrive? D0 1 is better than staring at mini? 2s is better, you can see the basic outline of the object.
abstract
That's all for today's sharing. The above suggestions are based on personal experience in purchasing tape recorders. If you want to buy a burner in the near future, you can make a reference. Anything wrong can be pointed out for discussion.
