The vehicle uses cigarette lighter socket to supply power to the Dash Cam, and 'Auto-off when no movement' is not turned on.
You can turn on the 'Auto-off when no movement' function and set a suitable 'Auto-off when no movement' time.

Note: After the vehicle is auto-off when no movement, you need to manually press the power button to turn on the Dash Cam when you start the vehicle next time.

The possible reasons are as follows:

1. This Dash Cam has a self-protection function. When the temperature is detected to be too high, it will not respond to the power-on action, please use it after the temperature is normal.
2. Please check whether the vehicle charger and power cord are abnormal.
3. After the vehicle is auto-off when no movement, you need to manually press the power button to turn on the Dash Cam when you start the vehicle next time.

The principle of HDR realization determines that under the setting of HDR+30fps, the frame encoding calculation is equivalent to 60fps;
If HDR and 60fps are turned on at the same time, the main control encoding processing capacity of mainstream Dash Cam is insufficient, therefore the two cannot be turned on concurrently.

This model of Dash Cam comes with F/1.8 large aperture lens and Sony 1/1.8 inch large target surface STARVIS2 image sensor, and its low light imaging capability is one of the leaders in the Dash Cam industry.
Complemented by the night driving and night parking security scenes specifically optimized imaging parameters, it can get outstanding image quality in the night without streetlights, low light parking spaces on the ground, underground garages and other dim scenes, which guarantees the effect of image algorithm analysis and forensics shooting.
The above 'low light' includes the following types of light sources:
- Fixed light sources on the road other than municipal streetlights, typically such as lights coming from roadside store signs and building windows on both sides of the road;
- Natural light sources at night, i.e., moonlight and starlight on clear nights;
- Mobile road light sources, typically such as the lights of vehicles on the next lane, the torch light held by passers-by.
In areas outside the range of municipal street lighting, with the help of the above low light sources, starlight night vision level Dash Cam can form a better night imaging, while the normal Dash Cam shot of such areas is too dark to see the details.
This is significant for improvement of the image quality of driving records and parking security at night in suburban and rural roads/parking spots.

This is caused by the interference on Wi-Fi signal of the Dash Cam. You can download the video to the local album of mobile APP to view to avoid this lagging problem.

Note: It is recommended to set the video recording length to 1 minute (the original segment length of the video file), which can be downloaded faster.

This is because the video uses high compression encoding, if the phone does not support H.265 (HEVC) decoding well, this problem will occur.
It can be played without problems by changing to a newer phone, such as using an entry Android phone launched in 2018 or a more powerful Android device, an iPhone 7 or a newer iOS device.
If you do not intend to replace the phone for the time being, you can set the video encoding format to 'low compression' in the Dash Cam settings interface on the phone, so that the subsequent recorded video can be played back normally by the old phone.

This is because the GPS search and positioning is not yet successful, please wait patiently.

Note:
1. If the metal film is attached to the front windshield, it will block the GPS signal to the vehicle cabin.
2. After equipping the Dash Cam with a 4G parking surveillance cable and enabling its 4G networking capability, the Dash Cam will automatically turn on the A-GPS function, thus greatly improving the speed and accuracy of GPS star search and positioning. (4G will be supported in October 2023)

The vehicle uses cigarette lighter Parking surveillance, time-lapse photography and motion detection are the corresponding working modes of this model of Dash Cam for different parking security scenarios. The Dash Cam supports the following functions alone or all enabled after detecting the vehicle flameout, to guard your vehicle in all aspects:

1. Collision detection: The Dash Cam will be in standby mode without recording after flameout, but when the built-in gravity sensor (G-sensor) detects abnormal vibration of the vehicle (usually the vehicle is collided), it triggers the recording of a 30-second-long parking surveillance video, and stores it in the parking surveillance video folder of the device album.
2. Motion detection: The Dash Cam will be in standby mode without recording when flameout. When the image algorithm running continuously on the Dash Cam detects a threatening scene to the vehicle and determines that the threat level has reached the level that needs to be recorded, it will trigger the recording of a 30-second-long parking surveillance video and store it in the parking surveillance video folder of the device album.
3. Time-lapse photography: When this function is turned on, the Dash Cam continuously shoots frames at a sampling rate of one frame per second (when the video recording frame rate is set to 30 fps) or one frame every 500 milliseconds (when the video recording frame rate is set to 60 fps) when the after flameout, and then combines them into a 30 fps or 60 fps video file, i.e. time-lapse photography video, and stores it in the time-lapse photography video folder of the device album. Time-lapse photography can continuously record the situation in the field of view of the Dash Cam, and playback the video at a speed equivalent to thirty times the real-world time flow, in case there is an abnormal event, it can well record the entire cause and effect as proof of evidence.

Note: If you installed the optional 4G parking surveillance cable for the Dash Cam, then the parking surveillance events triggered by collision detection or motion detection will be instantly sent to your phone via alarm message push to remind you to pay attention to the abnormal situation of your vehicle in time.

This is because the Dash Cam does not detect the parking surveillance cable. In this case, please start troubleshooting with the following:
1. Check whether the parking surveillance cable of the Dash Cam is correctly installed? If you do not have installation experience and firsthand ability, it is recommended to ask a professional to install it at an auto repair and maintenance store;for minority car models, it is recommended to contact 4S store first to get the vehicle fuse box circuit definition information for installation reference.
2. Check whether the parking surveillance cable has poor contact with the fuse box or with the Dash Cam.

The parking surveillance cable is an accessory used by the car Dash Cam in the parking security scenario and plays the following role:
- The cable takes electricity from the vehicle's battery to maintain a constant power supply to the Dash Cam when the vehicle is shut down, supporting the normal operation of parking surveillance, remote surveillance and other functions;
- When the vehicle battery voltage drops to a preset threshold, the power supply to the Dash Cam/4G module will be cut off to prevent low battery power, leading to the failure to start the vehicle.This model of Dash Cam only supports parking surveillance cable of 70mai brand.
You can choose the following models of 70mai parking surveillance cable to use with this model of Dash Cam:
1. 70mai 4G parking surveillance cable. In addition to supporting the parking surveillance function of the Dash Cam, it also enables the Dash Cam to obtain 4G network connection capability, thus enabling 4G network connection related functions, including instant push alarm message notification and video clips to your mobile APP when the Dash Cam triggers recorded parking surveillance video. As a parking surveillance cable accessory, this model supports three voltage protection threshold settings for low battery protection for cars (see specific Q&A below).
2. 70mai parking surveillance cable (USB Type-C power supply connector). This model does not support 4G network connection, if you choose this model, the Dash Cam will not be able to instantly notify you when the recorded parking surveillance video is triggered, but only remind you to use your mobile phone to access the Dash Cam to view the parking surveillance video recordings in the device album when you start the vehicle next time.

4G parking surveillance cable supports to choose three grades for setting the voltage threshold of vehicle battery protection:
• Low - 11.8/23.6 V
• Medium - 12.0/24.0 V
• High - 12.2/24.4 V

Note: The 12V battery trolley supports three-grade setting of 11.8/12.0/12.2V, and the 24V battery trolley supports three-grade setting of 23.6/24.0/24.4V.

You can choose the right battery protection voltage threshold by gradually turning down the grade according to the actual situation such as the capacity and newness of your vehicle battery, to get the longest parking surveillance usage time under the premise of protecting the battery.

Usually for new batteries (less than 2 years old) and large capacity batteries that support start/stop, you can select 'Low - 11.8/23.6 V' to get a longer usage time for parking surveillance (in a typical vehicle with a new start/stop battery installed, collision detection, parking surveillance, and time-lapse photography are all on, and the usage time is measured to be more than 5 days).

If you are not quite sure of the minimum battery voltage required to start your vehicle's engine, just keep the default 'Medium - 12.0/24.0 V' grade. If the battery is seriously aged or the vehicle requires high starting voltage (for example, vehicles with engines with a high number of cylinders such as V6, L6, V8, V12, W12, etc.), battery voltage dropped to 11.8 V may cause failure to start the engine.

This is a result of incorrect wiring of the parking surveillance cable on the vehicle fuse box. This may lead to the failure of the Dash Cam to properly enter the parking surveillance mode after the vehicle flameout. For this situation, it is recommended to consult a 4S store or professional repair store to clarify the wiring method for the constant power supply after flameout of your vehicle.

Note: non-professional changes to the car circuit may lead to battery failure or even vehicle self-ignition and other serious consequences, please be sure to address the parking surveillance cable installation wiring with the help of professional institutions.

The causes of this problem may be the following,
1. The Dash Cam does not turn on the function of collision detection triggering parking surveillance video.
2. In the Dash Cam settings, the collision detection trigger parking surveillance sensitivity setting is too low, you can try to set a higher sensitivity (for the vehicle with good chassis damping effect, it is recommended to set a high sensitivity).
3. In hot weather, the vehicle cabin temperature is too high, the Dash Cam automatically shuts down to protect the device, it will not be able to respond to the collision event to trigger the parking surveillance video after shutdown. You can apply heat insulation film to the windshield to solve this problem, and try to avoid parking the vehicle in direct sunlight for a long time in the hot season.
4. Low vehicle battery power triggers the battery protection function of the parking surveillance cable, and the power is cut off by the Dash Cam. For this situation, please choose the appropriate battery protection voltage threshold grade according to the condition of your own vehicle battery. If the battery is used for a long time and has been aging, please replace the new battery in time. In addition, the frequent start of the vehicle in a short period of time (such as a number of consecutive short-distance driving) will lead to insufficient battery storage, resulting in the battery protection function of the parking surveillance cable triggered soon after the vehicle flameout; in this case, you can start the vehicle to drive/idle for more than 30 minutes to fully charge the battery, and then turn off the vehicle to continue to use the parking surveillance.
5. This is a result of incorrect wiring of the parking surveillance cable on the vehicle fuse box. This can cause the Dash Cam to be shut down when the power supply to the Dash Cam is cut off some time after the vehicle flameout. For this situation, it is recommended to consult a 4S store or professional repair store to clarify the wiring method for the constant power supply after flameout of your vehicle. (Note: non-professional changes to the car circuit may lead to battery failure or even vehicle self-ignition and other serious consequences, please be sure to address the parking surveillance cable installation wiring with the help of professional institutions.)
6. Please note that even if the Dash Cam is set up with the highest collision detection sensitivity, for some types of collisions, such as courier drivers riding electric bikes passing by, the cargo box rubs against the parked vehicle at low speed, it is possible that the parking surveillance video will not be triggered. Gravitational acceleration sensors are more sensitive to vibrations caused by heavy objects; if a passing pedestrian or non-motorized vehicle causes damage to a parked vehicle, there is a probability that a relatively light action will not trigger the parking surveillance recording.
(Note: Actual testing of a certain SUV model with comfort as a selling point parked on a concrete-hardened surface, with the highest collision detection sensitivity setting, someone pressed a cigarette butt hard on the tire triggered the parking surveillance video.)

Either of the following methods can be taken to solve the problem,
1. Reduce the sensitivity setting for collision detection to trigger parking surveillance.
2. In the collision response policy of parking surveillance, set it to delay 5 minutes before responding.

If you have turned on the motion detection function in the Dash Cam settings (Note: The Dash Cam will detect the parking surveillance cable and will recommend turning on this function by default in the beginner's guide step).
When the vehicle shuts down and enters the parking surveillance, the Dash Cam will continue to shoot, and the built-in AI algorithm will continue to analyze the scene in the field of view.
If the algorithm determines that the threat level to the vehicle from a moving object in the scene has reached a level that requires recording, the Dash Cam will be instructed to begin recording a 30-second parking surveillance video to be stored in the built-in parking surveillance folder in the Dash Cam.
In this type of scenario, usually an object is moving continuously in close range in the field of view of the Dash Cam.

Note: The initial motion detection algorithm can only recognize human-shaped objects, and subsequent upgrades will add recognition of all types of vehicles (including non-motorized vehicles).

Motion detection supports three sensitivity settings of high/medium/low.
The difference between sensitivity grades lies in the recognition judgment of 'suspicious scene'.
The higher the sensitivity setting, the more lenient the AI algorithm is in screening the appearance of suspicious objects and the lower the requirement for the duration of objects in the field of view.

Note: For the image recognition AI algorithm, the judgment of suspicious scene is a comprehensive logic derived from training. Therefore, the algorithm parameters such as the duration of suspicious objects staying in the field of view are not fixed values and therefore cannot be set by the user.

This is because the scene in the Dash Cam's field of view is not determined as a sufficient threatening scene to require video recording by the AI imaging algorithm. The specific reasons could be,
- Cause 1: The duration of time the person remains in the field of view of the Dash Cam is too short (under the default sensitivity setting in motion detection, it needs to remain in the field of view for more than 20 seconds to trigger the parking surveillance video).
- Cause 2: Human imaging does not meet the requirements of AI algorithm for human recognition.
Main scenario:
• The person is obscured, which affects the detection effect of the imaging algorithm. For example, when the person is too close to the vehicle and only the part above the abdomen appears in the field of view of the Dash Cam, it is easy to be ignored by the algorithm and lead to missing recognition.
(Note: 70mai is continuously improving the recognition capability of AI imaging algorithm, and will subsequently strengthen the recognition of obscured human shapes and increase the recognition of various types of vehicles.)
• The person is too far away from the Dash Cam (more than five meters), and the image of the person is too small, which will be judged as low threat and thus will not trigger the parking surveillance video.
• Environmental factors, when shooting outward from inside the car, the field of view light situation is complicated, there are occlusions and reflections, such as too dark light or windshield reflections, which can interfere with the recognition algorithm.- Judgment of the method of motion detection function (depending on the specific vehicle model, installation angle, the actual performance parameters will vary: the difference range in distance is no more than one meter, and the difference range in retention time is no more than 5 seconds),
• High sensitivity: about 2-3 meters from the front of the car, stay for about 8 seconds, will trigger the motion detection
• Medium sensitivity: about 2-3 meters from the front of the car, stay for about 10 seconds, will trigger the motion detection
• Low sensitivity: about 2-3 meters from the front of the car, stay for about 17 seconds, will trigger the motion detection

No, it will not. Unlike the frame comparison principle based motion detection that is commonly used in the industry, the built-in imaging algorithm of this Dash Cam model will make intelligent judgments about the scene in the field of view, and the recording of parking surveillance video will only be truly triggered if the threat level of the scene is large enough as determined by the algorithm; this can greatly reduce the number of useless activity scenes triggering the recording of parking surveillance video, making the motion detection function truly practical in densely populated areas.
For example, in general, scenes with vehicles/people coming and going are not judged as threatening by the algorithm, but only when specific suspicious objects stay in view long enough and close enough to the vehicle.
The algorithm determines the threat level of the scene intelligently, not according to a fixed preset length of stay or distance.
In addition, if the same moving object stays in the field of view for a long time, at most two consecutive parking surveillance video recording events will be triggered, and the Dash Cam will then actively ignore the object to avoid repeated recording of parking surveillance video with very low or no value.

The possible reasons are as follows,
1. Low vehicle battery power triggers the battery protection function of the parking surveillance cable, and the power is cut off by the Dash Cam. For this situation, you can start the vehicle to drive / idle for more than thirty to fully charge the battery, and then turn off the engine to continue to use time-lapse photography; if the battery is aging, please replace the new battery in a timely manner.
(Note: For vehicles installed with start/stop battery, the fully charged new battery can support this model of Dash Cam to record about one week of time-lapse photography video.)
2. The Dash Cam automatically shuts down to protect the device due to high temperature. For this situation, you can apply heat insulation film to the car glass and try to avoid parking the vehicle in direct sunlight for a long time in the hot season.
3. The Dash Cam triggers the recording of parking surveillance video, or the user controls the Dash Cam to record video remotely via 4G, which will cause interruption of time-lapse photography, once the recording is completed, time-lapse photography will continue and stored as a new clip. (4G will be supported in October 2023.)

If you equip the Dash Cam with 4G parking and parking surveillance cable, and the device is properly networked, when the vehicle is shut down, you can enter the 'Remote Settings' page on the 'Remote Surveillance' page of the mobile APP to switch the on/off status of the collision detection parking surveillance/time-lapse photography functions.

Note: You can click the 'Effective immediately' button to switch the on/off status of these functions immediately; you can also exit the 'Remote Setting' page directly after switching on/off, and then when your mobile phone exits the 'Remote surveillance' page for 5 minutes, the on/off status of these functions will be switched automatically according to your settings.

This is because the lane line of the road section the vehicle is driving on is not clear, or the lens angle is not appropriate.
Please follow the steps below to eliminate the problem and re-calibrate,
1. Check whether the lens of the Dash Cam has been calibrated in accordance with the calibration process (Note: Turn off ADAS in the Dash Cam setting module at the APP end and then turn it on again, you can enter the lens calibration process again);
2. Ensure that the vehicle is driving at a speed greater than 40 km/h and on a road with clear lane lines;
3. Keep the lens clear of stains, dust and obstructions;
4. Restart the Dash Cam for recalibration (Note: available restart operations include unplugging the USB power cable from the Dash Cam body and plugging it back in; or long press the power button to turn it off, then click the power button to turn it back on).

Once ADAS function is turned on, all broadcast types will be turned on by default.
If you think the ADAS broadcast is too frequent and affects driving, please turn off the unnecessary broadcast types according to your actual needs by entering the ADAS setting page in the Dash Cam settings module of mobile APP.

Note: There is no concept of 'sensitivity' for specific ADAS broadcast items, such as front vehicle start reminder, and the triggering of these broadcasts is automatically judged by the algorithm according to the road scene.
Thanks to the improvement of both the image quality and ADAS algorithm of the Dash Cam, it is normal that the performance of the ADAS function of this model will be more active on some road scenes than on the earlier model of 70mai Dash Cam.

The possible reasons are as follows,
1. Rain and snow and other weather conditions: In bad weather conditions, for example, rain, snow, haze and other weather, the camera may not be able to properly photograph the vehicle in front, resulting in delayed or non-reporting of the warning.
2. Camera direction misalignment: camera direction misalignment may lead to incorrect identification of the vehicle ahead and failure to send a timely warning on the vehicle ahead;
3. Slow speed of the vehicle ahead: when the vehicle is too slow, the system may not consider it a hazardous situation, resulting in no warning being sent;
4. Driving habits: some drivers may turn off the ADAS warning function, please check if the function is on properly and if calibration has been completed.
For the case that the warning is delayed or not reported, it is recommended to check: whether the Dash Cam camera is clean, whether it is installed in the correct direction, whether ADAS is turned on, broadcasted accordingly and calibration has been completed.

The most possible reason is that the vehicle is parked in areas without satellite positioning signal, e.g., underground garage, indoor parking area, under the elevated area, dense high-rise buildings, etc. In this case, the parking position shown on the APP terminal is the last successful position of the Dash Cam before the vehicle flameout (usually it is near the entrance of the parking area, if there is an elevated bridge, tunnel culvert section or dense high-rise buildings near the entrance of the parking area, it could shift further. (This function requires the support of 4G parking surveillance cable, which will be available in October 2023.)

Possible reasons are
,1. High-grade heat insulation film containing metal is attached to the vehicle glass, which will block the GPS signal and cause the GPS device in the cabin to work improperly. You may consider installing a GPS signal amplifier to solve this problem.
2. When the vehicle drives through the road sections with serious GPS blockage such as tunnels, under bridges and high-rise buildings, it will lead to slow or even unable to locate the GPS, and after driving away from these road sections, the GPS can resume normal.

This model of Dash Cam is designed to consider this situation in advance, and it is unlikely to have the problem of not being able to boot up due to the external power disconnection during the OTA process. If the power of the Dash Cam is accidentally cut off or the OTA upgrade package is damaged during the upgrade process, it will lead to the Dash Cam crashing, in this case, connect the external power supply and press and hold the power button for 15 seconds to force restart the Dash Cam, then you can try to push the OTA upgrade package again and re-upgrade.
Attention! If the built-in battery of the Dash Cam is seriously aging after several years of use, then the unexpected power failure of the Dash Cam during the upgrade process will cause failure to turn on the Dash Cam. In case of this problem, it can only be returned to the factory for repair, there is no convenient repair method available to the user.

This model of device supports 4K images, which requires high transmission speed of memory card, please use U3 or above level memory card (recommended to use 70mai official card, high-end card from Longsys or Samsung, SanDisk, Kingston).

For 1-minute ordinary video using 265 encoding (high compression), 3840X2160 resolution, HDR enabled, 32G memory card, it is about 1.5 for dual recording of front and rear; and about 2 hours for front only recording. It then starts cyclic erase the earliest video (This is related to the details of specific road scenes,

if there is a lot of tree crown and other detailed scenery, the video file size will be slightly larger than the general road).If more storage is required, 64/128 GB memory cards can be purchased, and the available continuous recording time will be doubled compared to 32 GB memory cards, in accordance with the nominal capacity.

There are two methods as follows,

1. In the shutdown state, use a USB 3.0 or faster protocol compatible cable to connect the Dash Cam to the computer (mainstream versions of Windows/Mac/Linux computer systems are supported), after the Dash Cam is turned on, a removable memory disk drive will appear on the computer, and you can then copy the desired video or photo to the computer.
2. Take the memory card out of the Dash Cam and insert it into the computer using a card reader for viewing.

Please operate using a cable with data transfer function. The cable equipped with the Dash Cam is a power cable, which has no data transfer function.

Possible reasons are,

1. In hot weather, in direct sunlight to the Dash Cam area, the heat generated by the work of the car Dash Cam dissipates slowly, the accumulation of heat will lead to an increase in body temperature, which will affect the memory card slot.
2. Memory cards work continuously in the state of reading and writing on the Dash Cam, will also generate heat.

Regarding the memory card heating phenomenon, please note that:
1. Memory card heating will be more serious if the quality of the memory card is poor and the reading and writing speed is slow. Therefore, please choose a high-quality memory card with the required speed grade when buying Dash Cam.
2. Memory card heating is normal, but the long-term overheating of the memory card may affect its read and write speed and service life; therefore, please try to avoid using the Dash Cam in high-temperature environment, and regularly replace the memory card to ensure that the Dash Cam evidence taking work continues to be reliable.

Depending on the different memory card exceptions, the corresponding processing methods are,
- Low storage. The memory card size supported by this device is 32G-256 GB, please check the memory card capacity size.
- Low grade memory card. This device is a 4K Dash Cam, video data generated by the recording is very large, requiring high read and write speed of the memory card, please use U3 or above grade memory card; read and write efficiency will also be affected if the memory card is used for too long, please replace the memory card in time to ensure the normal operation of the device.
- The memory card needs to be formatted. Files are detected on the memory card that were not generated by the Dash Cam, or if a memory card is inserted into the Dash Cam for the first time for use, you will need to format the memory card first.
- Memory card damaged. This condition indicates that the memory card has run out of life. Please replace the card with a new one soon, otherwise the Dash Cam will not work properly.

Possible reasons are,
1. The phone Bluetooth is not turned on. Try to turn on the phone Bluetooth, and quit the APP and open it again.
2. Automatic Bluetooth pairing failed due to interference and other reasons. In this case, you can quit the APP and reopen it, and then try to connect to the Dash Cam directly; or go to the wireless LAN connection interface of the phone system to connect to the Dash Cam hotspot manually.

This is because of the restriction of the application API by Google play, which cannot obtain the corresponding data interface directly normally, therefore the function is not available on Android system.

RS visual effects is visual effects feature available on the high-end models of 70mai vehicle Dash Cam.

When playing back normal and emergency video footage in the app, with RS visual effects on, the APP will superimpose a technological visual effect on the screen to show information such as vehicle speed, direction of travel, elevation, lane description, distance to the front car, etc.

RS visual effects can help you visually recall your driving experience, recall your skills with a racing game-like perspective and view, or more carefully analyze the cause of the accident.

The process of 'combine RS visual effects' is to superimpose the graphic effects of RS visual effects to video frames and encode them into video files.
This requires calling the computing power of the phone hardware to re-encode the video clips, which is a high-load task for the performance of mainstream phones, so it will take longer (the better the phone performance, the shorter the time to combine RS visual effects for the same length of video clips).
If the phone runs another task while executing the encoding task, it may cause the encoding task to terminate unexpectedly and even cause the APP to crash, so this process is not allowed to switch to background execution.

The vehicle distance value is calculated by the ADAS function from the images taken by the Dash Cam, which will be more accurate on clear marked typical road scenarios, but less accurate on unmarked non-standard roads or in wild areas.

This is because the ADAS function is not enabled on the Dash Cam, these elements are presented based on the ADAS recognition results.
After the ADAS function is turned on and its calibration is successful, the lane line, distance and pedestrian warning signs will appear on the RS visual effects of the subsequent recorded video.

All of our dash cams have passed rigorous safety tests, providing multiple safeguards.
A. A810 is certificated by CE and FCC, ensuring its safety and reliability under all circumstances.
B. A810's actual testing and operating temperatures exceed the claimed values, but a slight deviation beyond the recommended working temperature range will not have any adverse effects.
C. A810's high-temperature protection mechanism enables the device to extend its operating time as much as possible in high-temperature environments while ensuring the safety of both the device and the vehicle.

The application of the supercapacitor is the combined use of button batteries and the supercapacitors. The supercapacitor itself can store very little power.
It will shut down immediately after power cut, risking the possibility that critical footages cannot finish recording in extreme conditions.The application of the lithium battery is using lithium batteries as a backup power source.
Even when the power is cut off, the dash cam will still be able to finish recording the emergency video. The drawback is that lithium batteries do not discharge well under extremely high or low temperatures.
We believe that the priority of the dash cam is capturing footage even in extreme conditions, so we chose the lithium battery solution and equipped it with precise safety protection logic.
However, based on extensive user feedback, 70mai will explore the supercapacitor solution in future products.

In hot weather, if the vehicle is parked in direct sunlight, prolonged exposure to sunlight can cause the cabin environment temperature of the vehicle to be too high, resulting in a rapid increase in the temperature of the recorder;
In this case, the recorder will automatically shut down under high temperature protection to extend the service life of the device.
