Why car camera pixels only 0.3 million while cellphone camera up to millions

¿Por qué las cámaras de los coches sólo tienen 0,3 millones de píxeles y las de los móviles millones?

/en /por

En la actualidad, es muy común que un teléfono móvil con una cámara de 8 millones, 12 millones o incluso 20 millones de píxeles, pero cuando se trata de la cámara del coche, podemos encontrar la normal cámara de marcha atrás sólo con 0,3 millones de píxeles, un cámara del coche con un millón de píxeles se consideraba una cámara HD, ¿por qué?

Why car camera pixels only 0.3 million while cellphone camera up to millions ?插图

La razón principal es que la industria del automóvil tradicional con características de “lento”, cualquier nueva tecnología y los productos que se utilizarán en el coche debe pasar por un largo período de I + D y verificación, el teléfono puede cambiar de generación una vez al año, pero el coche necesita por lo menos cinco años. Por supuesto, finalmente depende del mercado y del coste. Esta es una respuesta general a esta pregunta.

Desde el punto de vista técnico, si se trata de alta y baja temperatura, vibración, EMC problema, etc, puede ser totalmente diseñado de acuerdo con los requisitos del coche. Cámara del teléfono móvil con el chip de precio de consumo, está bien para cambiar el chip de nivel de coche en coche.

Si la técnica no es un problema, ¿por qué los píxeles de la cámara del coche siguen siendo tan bajos?

Un sistema de cámara completo debe incluir una cámara ( considerada principalmente como sensor de vídeo/imagen ), la transmisión de vídeo (incluidos CVBS LVDS y Ethernet) y el dispositivo de visualización (pantalla lcd).

En primer lugar, sensor de la cámara: en la actualidad cumplir con el sensor de requisitos de nivel de coche y ha sido la producción en masa es principalmente de 0,3 millones de píxeles de la cámara (que se utiliza en el coche de todo el mundo), y la cámara 720P ( con alrededor de 1 millón de píxeles ) dos tipos. El sensor de imagen 720P sólo ha madurado en los últimos años. En la actualidad, el precio de los dos sensores de imagen es alrededor de tres veces en la diferencia. Los requisitos técnicos se pueden cumplir, pero el coste final se incrementará relativamente mucho.

En segundo lugar, la transmisión:
Definición estándar: la actual cámara de calidad normal se utilizan CVBS formato de señal de transmisión, CVBS es probablemente utilizado hace veinte años en casa en la televisión por cable. Resolución de transmisión teórica es sólo unos pocos cientos de miles de píxeles. Este método de transmisión es muy maduro, y se ha utilizado en el coche durante mucho tiempo, no hay ningún problema. Y la señal se puede enviar directamente a la salida del sensor de imagen, sin chip de codificación adicional necesario, pero tiene un bajo requerimiento para el cable de transmisión. Sus ventajas son el coste y la estabilidad. La más importante es que la mayoría de la pantalla lcd reservado interfaz de entrada es también CVBS.
Alta definición: incluye dos tipos de LVDS y Ethernet. En primer lugar, el chip códec LVDS no es barato y el cable también es muy caro, por lo que sólo se ha utilizado en cámaras en los últimos años. Ethernet coche PHY también es muy caro, pero no hay necesidad de cable, aunque la Ethernet en el sector civil ha sido maduro, pero en el coche sólo unos pocos fabricantes de automóviles famosos como BMW se atreven a utilizar.

En tercer lugar, la pantalla, sigue siendo los problemas de interfaz de vídeo, porque casi todos los fabricantes de pantallas reservado la interfaz para cámaras de automóviles son CVBS, que sólo puede utilizar una cámara de 0,3 millones de píxeles. Para mostrar la cámara 720P, debe dejar de lado la interfaz de vídeo LVDS o Ethernet. Fabricantes de cámaras y fabricantes de pantallas no son generalmente la misma empresa, por lo que no sólo va a hacer cambios para usted, sólo fabricante de automóviles puede promover su cambio, y los fabricantes de automóviles son muy sensibles para el uso de las nuevas tecnologías y los costos , A menos que todos los competidores están utilizando, entonces van a considerar seriamente. Francamente hablando, nuestra empresa ha desarrollado la cámara del coche 720P hace dos años, pero hasta ahora todavía hay pocos fabricantes de automóviles nacionales realmente la intención de utilizarlo.

Técnicamente no hay ningún problema, el problema es que el fabricante de automóviles no está dispuesto a gastar tanta mano de obra y el costo. Para las cosas nuevas y la tecnología, en general, Europa y los Estados Unidos pueden tratar primero en el coche de lujo, a continuación, en el coche civil, y luego utilizar en el mercado chino a través de la empresa conjunta en China.Ahora un montón de coches de lujo en Europa y América utiliza una cámara de alta definición de 720p, y supongo que todavía necesita 5 años para ser popular en China y otros países en desarrollo de automóviles de clase civil, así que vamos a esperar a que it.People que no pueden esperar para comprar, puede comprar una cámara de visión trasera del coche 720p del mercado de accesorios, y el uso de una pantalla que puede coincidir con esta cámara del coche hd.

Dashboard camera frequent asked questions and problems shooting插图

1.during video capturing, dashboard camera will automatically stop, can not take images and videos, how to solve?

Reason analysis: Once shooting high definition video,the data will be larger data larger, each frame of video will be stored in the SD card during shooting, if use poor quality or low speed SD card for storage, memory card processing speed can not keep up with the required speed for dashboard camera recording , then the automatically stop phenomenon will be appear during video capturing, and can not take pictures or video.
Solution: Check if the memory card has enough space. Please use high speed memory card which compatible with dashboard camera, high-speed memory card usually has C4, C10 and other marks, we recommended you to choose C10 memory card. Check whether the loop recording function turns on in the menu,whether screen saver function turns off.

2.recorder recording is not continuous, recording for dozens of seconds then it stop, but after a while it began to record ?

Solutions: Turn off motion detection. May buyer set the motion detection function after receiving the camera,but many buyers do not understand the motion detection function. Motion detection is used when parking,it is not used when driving.Once turn on the motion detection function,if there are horizontal objects movement before the lens, the dashboard camera will record ; no horizontal objects before the camera it will not record.

3, When we play back pictures and video, appear “file error”, “memory card error” or “Custer size wrong. Please format” tips, how to resolve ?

Reasons analysis: As the shoot high definition video files stored in the low speed card or poor quality memory card,the memory card can not completely capture the video, resulting in file loss, the screen will appear “file error ”
Solution: Please use a computer to format the memory card, then format the memory card in the dashboard camera menu again; replace a genuine Kingston ,Sandisk or other brand name C10 high speed memory card. It is recommended to use the original memory card equipped with the dashboard camera or buy memory card from the seller, because you can ask the seller to test it with your dashboard camera model,so it fully comply with your dashboard camera.

4.Why the captured video or images foggy ?

Reasons analysis: if there are obstacles, dirt on the dashboard camera lens,or dirt in the car front windshield , it may cause unclear or foggy images and videos.
Solutions: Check if there are dirt, fingerprints on the camera lens; before shooting, use the lens paper to wipe the lens; check the lens protection film is torn off or not; the front windshield is clean enough or not, you can use dishcloth to wipe.

5.In the cloudy days or indoor light source, the image quality is not perfect ?

Reasons analysis: due to cloudy or indoor light scene, the surrounding environment is dim, shoot video quality is worse than video captured in enough light circumstances, this is the normal situation. But sometimes it may caused by wrongly white balance setting.
Solution: Please check whether the machine “white balance” function is set to automatic; set the exposure compensation level step by step and then check the display changes to determine the effect of setting; check the dashboard camera angle, the camera can not directly face the strong light, the correct placement is to maintain the dashboard camera in horizontal line,without too much deviation, the color change problem usually because of wrong settings,you can try to restore the default settings in the settings menu.

6.Press any key and does not react, can not set the menu and stop working;but pull out the TF card and you can set menu normally, how to resolve ?

Reasons analysis:dashboard camera use poor quality or low speed memory card; TF card internal circuit shortage; the charger not match the dashboard camera;frequent operate keys in a short time .
Solution: Replace current memory card with genuine Kingston or Sandisk memory card; use original charger; reset the dashboard camera;

7.Why the screen be black after recording for a period of time, but the lights still lit?

Reasons analysis: This is because the screen saver function (timer off screen) is set.
Solution: Press “MENU” to enter the system menu, select the “screen saver”, press the Enter key to enter, turn off the function.

8.The dashboard camera can working under normal circumstances, but after connect to the car charger, it can’t work?

Reasons analysis: This problem occurs because the car charger output voltage does not match the dashboard camera working voltage.
Solution: Please choose the right car charger for charging, 5V dashboard camera should use 5V output car charger. If the car charge voltage dropping module damaged,it will lead to too high output voltage, but if USB output voltage exceeds 6V or more, will cause the dashboard camera instability, or burn the dashboard camera power IC module .

9.Turn on the motion detection function at night for a while ,then dashboard camera lack of electricity ?

Reasons analysis: motion detection function is generally open during parking at night, parking off the car,the car will stop power supply to dashboard camera, as the dashboard camera built in battery can only supply about 3-10 minutes, if the dashboard camera needs continuously working at night, need to connect an external power source to the dashboard camera.
Solution: can be connected to power bank or automotive battery for power supply, but the power bank must have voltage monitoring and current monitoring functions, using of inferior brand power bank may also cause the dashboard camera’s motherboard IC power module damage.If you connect it with car battery, you need to use voltage dropping module with low voltage protection functions.

10.Dashboard camera can’t boot ?

Reasons analysis: whether the dashboard has enough voltage; whether the dashboard camera uses a high speed memory card; whether the dashboard camera can be powered normally.
Solution: Use the car charger to fully charge the dashboard camera; use the high speed memory card (C10 brand name memory card); charge the dashboard camera to see if it can be powered normally; press the RESET button to reset and restart the camera.

Reasons analysis: If the video loop function is turned on, this phenomenon occurs may because of two reasons: the dashboard camera gravity sensor set to a high sensitivity,gravity sensing is easy to trigger during working, so the recorded videos are protected, the protected video file can’t being overwritten by the loop; or use a poor quality or low speed memory card;
Solutions:Format the TF card or Press the “MENU” button to enter into the menu, select the gravity sensor, press the Enter key to enter, select “low” option.

12.Why the recording time is not my pre-set time frame ?

Reasons analysis: the software system segment and save the file sometimes not strictly in accordance with the set time ,but as long as the video will not missing a second,then it is OK. In addition,use poor quality or low speed memory card; open the motion detection function, or high gravity sensor sensitivity settings may lead to file segmentation not strictly in accordance with the set time.
Solution: Please format the memory card or replace with a high quality C10 high speed memory card; press the “MENU” button, enter the function menu, turn off the motion detection function, or set the gravity sensing sensitivity to low.

13.Image black or shiny?

Reasons analysis: As the brightness contrast during the shooting ,it is affecting the dashboard camera’s automatic exposure function.
Solution: You can correct by adjusting the exposure compensation (EV) value in the dashboard camera setup menu.

14.Dashboard camera noise a bit large during recording ?

Reasons & Solutions: Once the dashboard camera in low battery conditions,it will produce low power current noise. Of course, there are some dashboard cameras on the market using motherboard with worse filter design, no doubt their current noise will be large .Some times car charger interference will be obvious ,please try to change another car charger.

15.Dashboard camera can’t automatically recording when connected to car charger ?

Reasons analysis: Car charger voltage and dashboard camera voltage does not match; USB pin sequence is wrong; memory card does not have storage space.
Solution: Replace a car charger that matches the dashboard camera voltage; remove or format the contents in the memory card and turn on the loop video function.

16.Currently, the car battery output voltage is usually “12V, 24V”, I would like to ask if battery with these voltage value,can dashboard camera access for power supply?

Answer and solution: dashboard camera input voltage is 5V, original car charger charger output voltage is 5V,car battery output voltage is 12-24V, so the dashboard camera must use a voltage dropping line ( module ) to access 12-24V car battery, and can connect to car charger directly.

17.Once you set up an operation , how to save?

Solution: short press OK/REC button; then press the MENU button when exit, pre-set can be saved.

Reasons analysis: When the time setting is executed under low voltage (3.3V, normally 4.2V), the set time can not be memorized, resulting in the inability to save the current time setting.
Solution: It is recommended to set the time and date in the case of sufficient power.

19.Shooting the sky, the water and other scenes, the image is very dark, image color change, easy to distort, how to solve?

Reasons analysis: Larger contrast scene will affect the camera’s automatic exposure function, resulting in image discoloration.
Solution: You can correct by adjusting the “(Exposure Compensation) EV” value in the dashboard setup menu.

20.Dashboard recorder interfere radio?

Solution: unplug the car charger, use the built in dashboard camera battery to see if it still interfere the radio; to determine whether the car charger interfere or dashboard camera circuit interfere. Of course,if the same dashboard camera on the different cars, some cars were disturbed, and some cars anti-interference. Then the car charger and car radio frequency is repeated,please replace the car charger.

21.Get power supply from the fuse box or from the reading lamp ?

Solution: Better to get power supply from fuse box, connect the dashboard camera to fuse box with a voltage drop line , relatively simple and circuit can be checked easily.
Get power supply from reading lamp is more complex, you need to test the voltage and current, and must find the 12V output line and earth wire, you also need to observe the voltage changes before and after the engine starts.

To avoid unnecessary responsibility and road fraud in traffic accidents,more and more car owners considering to buy or already bought a driving recorder. Ms. Lee spent around $50 to buy a driving recorder. a month later, the plastic case edge of the driving recorder has been spoilt since the installation is close to the front windshield. Professionals warning that during purchase and use of driving recorder,consumers should be careful, because poor quality products may cause the vehicle to spontaneous combustion.

Avoiding bad quality driving recorder causing spontaneous combustion to vehicle插图

Car owners:buy driving recorder for different purpose

Reporters found that car owner buying driving recorder for different purpose. Most owners are to protect their own rights when the traffic police or insurance claims investigation on site after accidents.There are owners think that the vehicle damage is affordable, if involved in the casualties of traffic accidents, if there is no monitor or no witness, then there may be a big trouble, driving recorder may be useful at this time. While the owner Mr.Zhang has another purpose,he is particularly fond of self driving travel, during rest on weekends he often drive whole family to the suburbs to have fun, usually there are beautiful scenery along the road, but as he need to drive all the way, so he can only ignore these beautiful scenery, a driving recorder can help to automatically photographing beautiful scenery during driving .

Driving recorder industry insider:poor quality driving recorder may cause spontaneous combustion to the vehicle

A dealer told reporters in Beijing Automotive Products Exhibition, a dealer told reporters that although driving recorder has been popular for years, but there are still many bad quality driving recorder on the market,below are some common knowledge about driving recorder:
A).Driving recorder and GPS navigator is similar, tconnect the driving recorder to the cigarette lighter, it can only work during the car running , once the car stopped the driving recorder can’t work too. If the battery is installed, some recorders can only work less than two hours after parking. The vechiles being designated, stolen and other issues, the driving recorder simply can’t achieve 24 hours a day video recording functions.
B).The shooting angle is not wide enough. Recording angle recorded by driving recorder lens from 70 degrees to 170 degrees range, no matter how you adjust the driving recorder, it can only taken the video in corresponding angle.
C).There are a wide range of driving recorder in the market now, ranging from 30USD to 500USD. Usually those hidden built in mounting style driving camera quality is better. For driving recorder cost only 30-70USD, owner should pay more attention during purchase and use. Because those driving recorders will be connected to the cigarette lighter. The more cheaper the driving recorders are, the more inconsistent with the car part , once the driving recorder with poor power protection and poor accessories, it may easy happen line ignition phenomenon, it is likely to cause the vehicle spontaneous combustion. With the rising temperature, the overall temperature of the car will continue to rise too, especially in summer, the maximum temperature of inside the car may up to 60 degree, if the driving recorder accessories quality is not good, the ignition point is too low, it is easy to catch fire, and then causing vehicle spontaneous combustion.

Insurance company: they have encountered only a few driver with the recorder evidence

In a motor vehicle rapid claims center, the company’s staff told reporters that they are agents of many insurance companies quickly claims business, they has only encountered a few car owner use the driving recorder evidence.
It seems that most of the car owners install driving recorder with the original intention of evidence taken for the accident, but only a few of them really use these evidence .However,driving recorder is still considered to be necessary equipment for either old car or new car. But car owner should pay attention to the driving recorder quality. In addition, the driving recorder appearance is almost same as a mobile phone, better to install in a hidden place inside the car, so it won’t bring security risks to owner.

Tesla Model S is considered to be leading a revolution in the electric car market, from the Tesla new generation Model X SUV models, the company founder Elon Musk once again set off a change trend : replacing the traditional rear view car mirror with minicámara.

When Tesla Model X SUV debuted, its many features let people shine, such as “wing” style door, no traditional rear view mirror.Actually, Model X replaced the rear view mirror with a mini camera, and the images captured by the camera will displaying on the electronic touch screen lcd inside the cabin. Although this reduces the Model X wind resistance, but it also violated some of US security requirements.

Tesla spare no effort to promote replacing rear view mirror with mini camera插图

The regulations of the US authorities on the use of car mounted cameras should originally in effect in 2013, during which Tesla had been lobbying legislators to revise the law, allowing mini cameras to replace traditional rear view car mirrors, so US lawmakers have been postponing the law implementation. In 2016, Tesla,GM, Toyota, Volkswagen and other 12 members from car manufacturers Union ,made a proposal to the NHTSA, and recommended to use the rear view camera to replace the traditional car rear view mirror.

Replacement of the rear view mirror can simplify the car body structure, while reducing the wind resistance at the same time.Currently, improving fuel efficiency and car energy efficiency, become more and more important for car manufacturers and car owners. It is estimated that if use mini camera instead of rear view mirrors, the vehicle wind resistance will be able to reduce up to 5%. In fact, Volkswagen XL1 and some other car models, has been considered no longer using rear view mirrors for energy efficiency, but Tesla is the only one company really want to promote the legislative reform for car cameras.

Ventajas de la tecnología WDR para la cámara del salpicadero

¿En qué beneficia la tecnología WDR a tu cámara de salpicadero?

/en /por

WDR (rango dinámico amplio) es una tecnología utilizada para garantizar que la cámara pueda capturar vídeo o imágenes con un contraste muy intenso. En términos generales, se refiere a la región entre el cambio del valor máximo al mínimo o tal vez el valor mínimo al máximo .

How WDR technology benefit your dashboard camera ?插图

Por lo general, en el caso de una fuerte exposición a la luz o de baja luminosidad y otras condiciones de brillo relativamente bajo, el vídeo o la imagen tomada por la cámara aparecerá particularmente brillante o puede ser particularmente oscura, el área brillante se debe a una exposición excesiva y la pantalla oscura se debe a la falta de exposición, afectando gravemente a la claridad y calidad del vídeo. Esta restricción es lo que solemos llamar “rango dinámico”.

En resumen, la cámara de salpicadero tradicional cuando se elige utilizar 1/100 segundos para obtener la imagen expuesta en el interior del coche, a continuación, las imágenes fuera del coche en la luz puede ser blanqueada en condiciones de fuerte exposición o de bajo brillo, si continua en 1/10000 segundos hacer segunda exposición a las imágenes exteriores, a continuación, la imagen interna puede ser erradicada o ser negro, cuando las dos imágenes se fusionaron juntos con el tiempo reducirá la imagen final o la calidad de vídeo, que es también la escasez de la cámara tradicional.

Cámaras de salpicadero con tecnología WDR puede manejar el contraste de la fuente de luz, mejorar la calidad de las imágenes y la claridad, incluso en condiciones de exposición excesiva fuente de luz o el medio ambiente ultra oscuridad, que son capaces de disparar imágenes de alta calidad.

dash cam 5 trampas de compra que debes evitar

Dash cam 5 trampas de compra que debes evitar

/en /por

Desde el fraude de tráfico es más común ahora, dash cam ( también llamada cámara de salpicadero, dashcam, La cámara de salpicadero se ha convertido en un equipo imprescindible para el coche. Además de conservar pruebas y proteger a los propios conductores, la cámara de salpicadero también puede grabar los momentos divertidos y a lo largo del paisaje durante la marcha del coche.

Dash cam 5 buying traps you should avoid插图

Pero hay tantos dash cam en el mercado, el precio que van desde unos pocos dólares a varios cientos, y el alto precio dash cam por lo general vienen con muchas funciones, pero después de su uso puede encontrar estas funciones no es tan útil como la guía de compra said.How podemos evitar la compra de trampas, no gastar dinero? vamos a echar un vistazo a continuación.

Trampa uno: los píxeles del objetivo de la cámara, cuanto más altos mejor

Algunas guías de compra le recomendarán una dash cam de píxeles relativamente altos, los píxeles de las dash cam actuales en el mercado van desde varios millones a 10 millones de píxeles, naturalmente, cuanto más píxeles más caro. Pero en general, 2 millones de píxeles 1080P dash cam es lo suficientemente potente como para capturar vídeos claros de conducción. Los sensores de píxeles más altos no sólo reducirán el tiempo de grabación, sino que también aumentarán en gran medida el número de veces de reescritura de la tarjeta de memoria, lo que conducirá a una vida más corta de la tarjeta de memoria.

Segunda trampa: cuantas más funciones, mejor

Algunas guías de compra recomendarán al consumidor comprar una dash cam todo-en-uno, con perro electrónico adicional, cámara de marcha atrás, función de navegación GPS o algo además de la función básica de grabación de vídeo de conducción, y el precio naturalmente aumentará. De hecho, debido a las múltiples funciones comparten la misma CPU, todo-en-uno dash cam rendimiento se reducirá significativamente, y el efecto no puede hasta el efecto como se dijo, además, la vida útil será más corta que la sola función dash cam también.

Trampa tres: el rendimiento de las dashcams con chip Ambarella será mejor

La mayoría de los vendedores le dirá que su cámara de tablero es adoptar el chip Ambarella A7, pero simplemente no le dirá el número exacto de chip A7. El chip Ambarella serie A7 se divide en alta, media, baja tres clases diferentes, respectivamente, es LA70, LA50 / LA55, LA30, chip de bajo grado de rendimiento chip A7, naturalmente, no tan bueno como el de gama alta chip Ambarella A7.

Trampa cuatro: ángulo de visión cuanto más amplio mejor

Algunas guías de compra le recomendarán una dash cam super gran angular, con un gran ángulo de visión su área ciega será menor. De hecho, aunque el gran angular puede reducir la zona ciega, también distorsionará la pantalla, cuanto más amplio sea el ángulo de visión más grave será la distorsión, los efectos de vídeo también se verán afectados. En general, 120-150 grados de ángulo de visión dash cam puede satisfacer las necesidades de la mayoría de los conductores. Antes de comprar una dash cam con ángulo de visión de 170 grados o incluso 200 grados, considérelo cuidadosamente. .

Trampa cinco: la dash cam puede estar 24 horas vigilando mientras aparcas

Sin embargo, por un lado, la batería incorporada en la cámara y la tarjeta de memoria sólo puede soportar vídeo de 8-16 horas, es difícil lograr un seguimiento de 24 horas; por otro lado, el ángulo de seguimiento de la cámara es limitado, sin duda no puede lograr un seguimiento completo. Así que si usted quiere tener una cámara de vigilancia de 24 horas para su coche no es realista, si la guía de compra recomendar esta característica para usted, entonces él debe estar mintiendo .

Aunque es un poco complejo elegir un grabador de conducción dash cam, siempre y cuando evites estas trampas, ser tramposo puede reducir en gran medida la elección.

Dashboard camera recorder is now the basic equipment of many vehicles. Install the dashboard camera can protect driving security;and avoid of road fraud at the same time. But if dashboard camera recorder installed in the wrong position, not only can not ensure driving security, but may also increase the front blind area, and bring a great security risk for driving .Below are the dashboard camera installation mistakes user should avoid:

Wrong positons you should avoid during dashboard camera installation插图

1.The power cord is placed in the middle

Part of car owner install the dashboard camera with the power connection line directly in the middle of the the vehicle. This may result in the power line dangling during driving, and affecting the driver’s eye sight, thus bringing security risks. The correct way is to go through the power connection line in a hidden way,such as hidden in the interior joints, or be placed in the seal.

2.Installed at the top right of the front window

Some car owners think that dashboard camera installed in the front window , which make is closer to the sponge, and will not affect the eye sight. In fact, this position will lead to the dashboard camera effect greatly reduced. Although current dashboard camera view angle is not small, but the wrong position may make the front blind area greatly increased, resulting in opposite effect. After all, only the dashboard camera achieve the maximum effective view angle can it be better record the surroundings.

3.Connect dashboard camera power line with the reading lamp power supply

As the reading lamp power supply is relatively independent, and the reading lamp power supply position very close to the front glass, many vehicle owners directly open the reading lamp shell, and connect dashboard camera to the power supply circuit for reading lamp. So even if the car power off, the dash camera can still working by consumption of automotive backup power. This may result in driver can’t ignite the car next time, because the backup power is exhausted by the dashboard camera.

For the dashboard camera installation position, rear view mirror back side is the best position, with the best vision.
