Please check whether your mobile phone supports HEVC decoding, if it doesn’t, playback of the high compression coded dash cam video will not be available.

This problem will not occur in mobile phones produced in the last four years. The 70mai APP will automatically detect whether the phone supports HEVC decoding and provide setting suggestions.

This is to realize the anti-flicker effect on AC light source under HDR effect. You can set the anti-flicker frequency according to the local AC frequency.Refer to the corresponding recording frame rates for each setting:
•60Hz for 30 fps video recording
•55Hz for approximately 28 fps
•50Hz for 25 fps

This model is equipped with hardware-level HDR capability, which can greatly optimize the imaging effect in scenarios with strong brightness contrast, such as the following:

•Entering and exiting tunnels or underground garages during the daytime on a sunny day
•Headlights shining directly on the license plate of the vehicle at night
•Shadow imaging of objects on the road in areas exposed to strong sunlight.

As an entry-level model, this dash cam provides 1080P resolution, which is the general resolution offered by products of this grade.

As a video recording device, resolution is not the only factor that determines the picture quality.This model comes with an excellent hardware that delivers well-tuned image quality. Even when the resolution is set to 1080P, with features such as the robust master control, starlight night vision level advanced sensors, hardware-level HDR capability, high-quality lens, the resolution of the details remains outstanding compared with other mainstream 1080P dash cams on the market. In fact, it offers higher color fidelity and better imaging in complex light scenes.

This model is equipped with F/1.8 large aperture lens and starlight night vision level image sensors, allowing for excellent low-light imaging capabilities, which are supplemented by specially optimized imaging parameters for night driving and night parking security. In scenarios with dim lighting, such as traveling at night on roads without street lights, parking in parking lots with dim lighting, dim underground garage, etc., the dash cam can provide outstanding image quality for image algorithm analysis and evidence acquiring.

The 'dim lighting' mentioned above includes the following types of light sources:

•Fixed light sources on the road other than street lights, typically roadside store signs and light from windows of buildings on both sides of the road.

•Natural light sources at night, i.e. moonlight and starlight on nights where skies are clear

•Moving roadway light sources, typically the lights of vehicles in adjacent lanes, and the lights of torches held by pedestrians passing by.

In the areas devoid of municipal street lighting, with the help of the above dim light sources, dash cams equipped with starlight night vision functions can achieve better nighttime imaging as compared to ordinary dash cams, which cannot capture the details.

This is important for recording in parking spaces in relatively remote places such as the suburbs and countryside areas as it provides enhanced image quality for driving and parking security.

In addition, this model supports hardware-level HDR mode, which can reduce the over-exposure of highlights from glaring light sources during various scenarios. Examples include situations where the headlights of vehicles shine directly at the license plates of other vehicles, light box advertisements on the roadside, neon lights and other objects that emit light, all of which can be clearly captured against dark backgrounds.

This model is an entry-level dash cam that cannot support various types of optional 70mai external expansion cameras.

With this model, the recording of emergency video can be triggered in the following situations:
•Collision detection
•Voice control：lock the video

The emergency video is continuously recorded for 30 seconds from the point of trigger.

The emergency videos are erased in a separate cycle, and the upper limit of their storage space is 16% of the total available storage space of the memory card.

The logo watermark on the dash cam screen can be turned off. Simply select the 'dash cam settings' tab on the device or on your mobile phone to turn off the watermark. However, the date and timestamp cannot be turned off.

This dash cam model does not support GPS satellite positioning, so the vehicle speed and latitude/longitude are not indicated by watermarks.

This model supports collision detection, parking surveillance and time-lapse photography to enhance security when the vehicle is parked. The following functions can be enabled individually or simultaneously to enhance surveillance of the car when it detects that the vehicle is off:

1. Collision detection: When the vehicle engine is switched off, the dash cam is in standby mode and video recording will be paused. However, when the built-in G-sensor detects an abnormal vibration of the car (which usually happens when the car is involved in a collision), 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. Time-lapse photography: After enabling the time-lapse photography function, the dash cam will continuously capture images at a sampling frequency of 1 fps after the vehicle engine is switched off, then synthesizes them into a 30-fps video file, i.e. time-lapse video and stores them in the time-lapse video folder in the device's photo album. Time-lapse photography allows for continuous recording of the dash cam's field of view and the recorded images can be replayed 30 times faster than real time. In the case of an accident or unusual event, it can better record the entire process, making for effective evidence.

This occurs when the parking surveillance cable cannot be detected by the dash cam. During such situations, please perform the following checks:

1. Check whether the parking surveillance cable of the dash cam has been installed and connected correctly. If you have no experience or knowledge about installation, hands-on ability, it is recommended that you visit an automotive repair and maintenance store for professional installation services. For niche models, you are recommended to first contact the 4S dealership store to obtain the vehicle fuse box circuit definition information for installation reference.

2. Check whether the parking surveillance cable, the fuse box, and the dash cam host are connected properly.

The parking surveillance cable is an accessory utilized in the dash cam for parking security. It is used for the following functions:

•Drawing power from the battery of the vehicle in order to maintain the constant power supply to the dash cam after the vehicle engine has been switched off. This allows for the functions of normal operation of parking surveillance and time-lapse photography;
•To prevent the battery from being drained and the car from malfunctioning, the cable cuts off the power supply to the dash cam when the voltage of the battery has decreased to a preset threshold.

The 70mai parking surveillance cable (USB micro–Type B power supply interface) is compatible with this dash cam model. This accessory does not support the battery protection voltage threshold setting, and the fixed protection threshold is 11.8 V.

This is due to the incorrect wiring of the parking surveillance cable on the vehicle fuse box. This may result in failure enter parking surveillance mode correctly after the vehicle engine is turned off.

In such situations, you should consult a 4S dealership store or professional workshop to ensure that the circuit wiring does not cause the power to be disconnected when the engine is off. (Note: Arbitrary alteration of the vehicle’s circuit may lead to serious consequences such as battery failure or even spontaneous combustion of the vehicle. Hence, please make sure to resolve the parking surveillance wire installation and wiring issues with the help of professionals.)

This issue may occur due to the following reasons:

1. Parking surveillance video is not being recorded and collision detection is not triggered.
2. This may be because the sensitivity of collision detection triggering and parking surveillance has been set to a low level in the device settings. Try to set a higher sensitivity (For models with better chassis damping effect, it is recommended to set a higher sensitivity).
3. When the temperature of the vehicle cockpit becomes too high during hot weather conditions, the dash cam automatically shuts down to protect the device, Hence, it will not be able to respond to a collision event to trigger the parking surveillance video after the shutdown. To avoid this problem, apply a heat shield film to the windshield screen of your vehicle, and try to avoid parking the vehicle under direct sunlight for long periods of time during the hot season.
4. For instances where the low battery level of the car triggers the battery protection function of the parking surveillance cable and the power of the dash cam is cut off, please choose the appropriate battery protection voltage threshold gear according to the condition of your own vehicle battery. If the battery has been used for a long time, please replace it in time. Moreover, starting the vehicle repeatedly within a short period of time (e.g., making consecutive short-distance trips) will lead to insufficient power reserve. This will trigger the battery protection function of the parking surveillance cable soon after the vehicle is turned off. During such occurrences, you should start the vehicle and drive/let it be idled for more than 30 minutes to ensure that the battery is fully charged. Then, turn off the engine to use the parking surveillance.
5. This is due to incorrect wiring of the parking surveillance cable on the vehicle fuse box. This can cause the dash cam power supply to be cut off some time after the vehicle is turned off, causing the device to shut down. In this situation, it is recommended that you consult a 4S dealership or a professional workshop to make sure the circuit cable is not disconnected from the power supply after the engine is turned off. (Note: Randomly altering the car circuit may lead to serious consequences such as battery failure or even spontaneous combustion of vehicle. Hence, make sure to resolve issues with the parking surveillance cable installation and wiring with the help of professionals.)
6. Please note that despite setting the dash cam with the highest collision detection sensitivity, it is possible that the parking surveillance video will not be triggered for some types of collisions, such as pedestrians riding motorized scooters passing by at low speeds and brushing against parked vehicles. Gravity 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 the parking surveillance recording function will not be triggered if the movement is relatively light or minor. (Note: In an actual test, an SUV that emphasizes comfort as the selling point was parked on cemented ground and set to the highest sensitivity for collision detection. Someone then pressed a cigarette butt hard against the tire to trigger the parking surveillance video recording.)

Collision detection parking surveillance function supports high/medium/low sensitivity settings.

The difference between each level of sensitivity is in the judgment of collision recognition, the higher the sensitivity setting, the lower the threshold for determining the collision.

You may apply any of the following solutions to solve the problem:
1. Turn down the sensitivity setting for collision detection triggering parking surveillance.
2. Configure the collision response time of parking surveillance to 5 minutes after the vehicle has been powered off.

No. The parking surveillance function and motion detection of the 70mai dash cams is based on continuous analysis of the scene using AI image algorithms, which have high requirements for the master control of the dash cam's computing power. This dash cam is an entry-level model which has a master control that cannot support AI algorithms.

This issue may occur due to the following reasons:
1. The power reserve of the car battery is low, causing the battery protection function of the parking surveillance cable to be triggered, thus cutting off the power of the dash cam. To address this situation, drive the vehicle/let it be idle for more than 30 minutes to fully charge the battery. Then, turn off the engine and continue using the time-lapse photography feature; if the battery is aging, please replace it in time. (Note: For vehicles equipped with a start-stop battery, a fully charged new battery can support the dash cam to record time-lapse video for approximately one week.)

2. The dash cam may shut down automatically due to excessively high temperatures in order to protect the device. In such situations, place a heat insulation film on the glass and try to avoid parking the car in direct sunlight for a long time in the hot season.

3. If the dash cam is triggered and begins recording the parking surveillance video, it will cause the time-lapse photography to be interrupted. After the recording is completed, the time-lapse photography will resume and be stored as a new segment.

As an entry-level model, this dash cam does not support ADAS.

As an entry-level model, this dash cam does not support GPS (the hardware does not come with a GPS module). Therefore, it does not provide driving routes, latitude/longitude, and other functions related to vehicle location.

As an entry-level model, this dash cam is not equipped with Bluetooth functions. If you wish to use the 70mai APP to access the dash cam hotspot, you will need to manually connect your mobile phone to the Wi-Fi hotspot of the dash cam on the Wi-Fi connection interface of the mobile phone system. After doing so, enter the 70mai APP to connect.

This is because the Wi-Fi signal of the dash cam is affected by various sources of interference. You can download the video to the local album with the APP to view to solve this problem.Notes: It is recommended to set the video recording length to 1 minute (the original segmented length of the video file), which allows for faster downloading.

This is due to the high compression coding used in the video. It can occur if the phone does not support H.265 (HEVC) decoding function. You may try with a new mobile phone. This should not be an issue with the entry-level Android phones or Android devices with better performance launched in 2018, iPhone 7 or newer iOS devices.If you do not intend to replace your phone for the time being, you can set the video encoding format to 'low compression' in the dash cam interface on the phone. As a result, that the subsequent recorded videos can be replayed back normally.

After the video/photos and other image files have been downloaded from the dash cam to the mobile APP, they are all stored in the '70mai' album in the system album of the mobile phone. You may access and manage these image files in the system album or in the local album of the 70mai APP.

This is because the car runs on normal power, with the cigarette lighter plug supplying power to the dash cam when the function of 'auto power off with continuous inactivity' is disabled. After the engine is turned off, the vehicle continues to supply power to the dash cam, allowing the dash cam to remain powered on.

Enable the 'auto power off with continuous inactivity' function and set an appropriate time for 'auto power off with continuous inactivity'.Note: After enabling the function of 'auto power off with continuous inactivity' for a normally powered car, you will need to manually press the power button to power on the dash cam the next time.

This dash cam model requires a power supply with 5V/2A input, and it is recommended to use an official 70mai power supply accessories. If you prefer using a third-party power supply accessory, please make sure to opt for an accessory with power supply specifications that meet the requirements and comply with national safety regulations.

It may be due to the following reasons:
1. This dash cam is equipped with a self-protection function that prevents the device from powering on when excessively high ambient temperature is detected. In such situations, please wait for it to cool down to normal temperature before use.
2. Please check whether the car charger and power cord are abnormal.
3. After enabling the function of “auto power off with continuous inactivity” for a vehicle that is normally powered, you will need to manually press the power button to turn on the dash cam the next time you use it.

As an entry-level model, this dash cam does not support 4G connectivity and is not compatible with the 70mai 4G Hardwire Kit for the 70mai dash cam.

The design of this model is intended to address such situations, and it is unlikely that the problem of failure to power on due to external power disconnection during OTA will occur. In the event that the dash cam experiences an unexpected power failure or the OTA upgrade package is corrupted during the upgrade process, it will cause the dash cam to crash. When that happens, connect the external power supply and long press the power button for 15 seconds to force the dash cam to restart, after which you can attempt to push the OTA upgrade package again and proceed with the upgrade.

Please note! If the built-in battery has severely deteriorated after several years of use, a sudden power loss during the upgrade process might prevent the dash cam from powering on. In this case, the only solution would be for the dash cam to be returned to the factory for repair. Unfortunately, there is no user-friendly repair method available for this situation.

Due to the product characteristics, the memory card of dash cam needs to be formatted frequently, resulting in specific demands on the transfer speed of the memory card. Please use a U1/Class 10 or above memory card (there are more inferior products for this class of card on the market, with poorer durability and performance. It is recommended to use the official 70mai card or TF card from brands such as Longsys, Samsung, SanDisk, Kingston). Ensure that the stated capacity of the memory card is not any less than 16GB.

Normal videos using high compression coding in 1080P resolution and HDR mode will occupy approximately 2 hours of storage on a 16GB memory card. After that, it will start the cycle of erasing the earliest video (the exact recording duration may vary depending on specific road conditions.

If there are a large number of tree canopies and other detail-rich scenery, the video file size will be slightly larger compared to videos of general road scenes).If you need more storage, you may opt for memory cards with 32/64/128 GB storage. Compared to 16 GB memory card, the available continuous recording time and capacity of these cards is doubled or many times more.

This dash cam can support memory cards with storage ranging from 16 GB to 128 GB. The recommended memory card grade is U1/Class 10 or above (It is recommended to use the official 70mai card, or TF card from brands like Longsys, Samsung, SanDisk, Kingston, and so on).

Please note that the 256 GB memory card may not work on this model. If you need to use a 256 GB memory card, please try to opt for products of the High Endurance series of renowned and trusted brands.

There are two possible reasons:

1. You may have used a memory card with a storage capacity of 16 GB.With a 16 GB memory card, there will be up to 2 hours of continuous recording before the first video gets erased when in high compression coding / HDR and recording. (The exact recording duration may vary depending on specific road conditions. If there are a large number of tree canopies and other detail-rich scenery, the video file size will be slightly larger compared to videos of general road scenes). If you need the whole video data, please connect the data cable to the dash cam to connect it to the computer after about 2 hours of continuous video recording. You may export the video file for backup or download it to the local album after connecting the APP.

2. Emergency video or parking surveillance videos take up too much space.For this reason: Emergency video and parking surveillance video are erased separately. The dash cam is designed to continuously occupy a fixed percentage of their built-in memory if there are too many emergency videos or parking surveillance videos recorded. Download your desired video clips to your mobile phone or connect your computer to export and back them up. Then, you may continue using the dash cam after deleting all the emergency videos or parking surveillance videos from the dash cam.

(Note: If you prefer continuous recording, try to opt for a high-capacity memory card and select low resolution and 'No Sound Recording' in the dash cam settings to obtain the longest available continuous recording hours.)

There are two methods:1. Turn off the dash cam and connect it to the computer using the data cable supporting USB 3.0 or faster (support mainstream versions of Windows/Mac/Linux computer systems). Once the dash cam is turned on, the removable memory disk will appear on the computer, after which you can copy the needed video or photos to the computer.2. Remove the memory card from the dash cam and view its contents on a computer using a card reader.

Please use a data cable with data transmission function. The dash cam is equipped with a power cord without data transmission function.

Possible reasons include:
1. Hot weather: dashcam exposed to direct sunlight. The heat generated by working dash cam is slow to dissipate and the accumulation of heat leads to increased body temperature, hence affecting the memory card slot.
2. The memory card is in the state of continuous reading and writing when working in the dash cam, which will also generate heat.
Things to note regarding memory card heating:
1. If the quality of the memory card is poor and the reading/writing speed is slow, the heating of the memory card will be more severe. Therefore, when purchasing a dash cam, please make sure to also purchase a high-quality memory card with a speed rating that meets the requirements.
2. It is normal for the memory card to heat up, but if the memory card is overheated for a long time, its reading/writing speed and service life may be affected. Therefore, please try to avoid using the dash cam in a high temperature environment and replace the memory card regularly to ensure its reliability.

According to different memory card abnormalities, the issues can be addressed with the following methods:
•Low memory card capacity: The memory card capacity supported by this device is 16G-128 GB, please check the memory card capacity.
•Low memory card quality: Video recording generates a large amount of video data, which requires high reading/writing speed of the memory card. Please use memory cards of U1/class10 and above. If the memory card has been used for a long time, the reading/writing efficiency will deteriorate as well, so please replace the memory card in time to ensure the normal operation of the device.
•The memory card needs to be formatted. When a memory card is detected to contain files that were not generated by the dash cam, or is used on the dash cam for the first time, it needs to be formatted.
•The memory card is corrupted. This situation indicates that the memory card’s life span is up, so please replace the card with a new one as soon as possible. Otherwise the dash cam will not work properly.

Adjust the speaker volume level in the dash cam settings, which can be set to high/medium/low and off according to your preferences.

This dash cam supports voice-enabled prompts. The scenarios of the prompts are as follows:Active trigger by the user:
•Turn on for the first time
•Upgrade

Automatic trigger by the system:
•When in parking surveillance mode
•Detect new parking surveillance video when power on
•When in time-lapse photography mode
•When the dash cam finishes receiving the upgrade pack from the mobile phone (the dash cam reboots to start the upgrade)
•Prompt of auto power off when overheated
•Power on after system time is reset (every time before the time is finally set)
•Detect that the memory card needs to be formatted.

This model supports the following command words:'I want to take a photo','I want to lock the video','turn on audio','turn off audio.'
