Memory card instructions

Storage space description

This dash cam supports standard MicroSD cards. Please use 16~64 GB memory cards that have a rating of Class 10 or above. Before using a new memory card, please format it in the dash cam. The number of videos that your memory card can hold depends on its capacity. See the following as a reference:

Type16 GB32 GB64 GB
Normal videoApprox.1.5 hoursApprox.3 hoursApprox. 6 hours
Emergency videoApprox.12 timesApprox.25 timesApprox.45 times
Parking surveillance video10 times20 times40 times
Photo300 photos

Normal video and emergency video both use loop recording. Make sure that you immediately export important videos to your phone, computer, or another device to ensure they are not erased.

The memory card may become damaged or deteriorate after repeated cycles of overwriting, this may affect its ability to save video files. If this occurs, you should immediately replace it with a new one.

Please use a reliable, high-quality memory card produced by a reputable manufacturers. Inferior memory cards may have issues including writing speeds that do not match the card’s stated ratings and capacities that are lower than their stated amounts. We are not responsible for any loss or damage to video or images caused by the use of an inferior memory card.

In order to avoid reading and writing speeds decreasing after prolonged use, we recommend formatting the memory card in the dash cam every two weeks. Please note that formatting will delete all files on the memory card. Therefore, please save all important videos and photos before starting this process.

Do not insert a memory card while the camera is on.

Memory card error description

If the memory card encounters an error that prevents recording, notifications related to the memory card error will be displayed. Follow the instructions given by the notifications. Memory card error notifications include:

  • Memory card is smaller than 8 GB
  • Memory card’s reading and writing speeds are less than Class 10 rating
  • Memory card’s performance is declining
  • Memory card’s writing speed is slow
  • Memory card identifying error
  • Memory card contains files that are not recorded by the dash cam
  • Memory card’s format is incorrect. When inserted for the first time, the memory card needs to be formatted by the dash cam prior to use.

Parking surveillance

The parking surveillance function is disabled by default. Go to Settings > Parking surveillance to enable it.

After you enable the parking surveillance function, whenever the power is turned off, the dash cam will enter parking surveillance mode. If the vehicle is hit by another car while in this mode, the dash cam will automatically start recording a parking surveillance video and save the footage in the parking surveillance video directory. The next time the camera is turned on, it will notify the user to view this footage.

If the cigarette lighter continues to supply power to the dash cam after the vehicle is turned off, then the dash cam will enter parking surveillance mode 20 minutes after the car has been parked. In this situation, the parking surveillance function may continue to be powered by the vehicle’s battery, and it could significantly deplete the battery if the car is not driven for a long period of time. When vehicles like these use the parking surveillance function, it is recommended that you use a parking surveillance cord with battery protection.

Parking surveillance relies on an accelerometer to detect collisions while the car is parked. Due to the complexity of the environment in which your vehicle may be located, we cannot guarantee that the dash cam will be able to accurately determine every collision that occurs, and there may be accidental or incorrect detections reported. If frequent false reports are being generated due to non-collision-related vehicle movement, you can disable the parking surveillance function.

Power supply instructions

The dash cam uses the vehicle’s cigarette lighter as its power supply. In order to ensure the power supply remains stable, please use the included car charger and power cord. The company is not liable for any loss or damage caused by the use of other power sources (a power supply other than the vehicle’s cigarette lighter), chargers, or power cords.

Certain vehicles continue to supply power to the cigarette lighter after the vehicle is turned off. In order to avoid battery drainage caused by the dash cam being used for an extended period of time, if you have not enabled the parking surveillance function, please make sure to manually turn off the dash cam or unplug the charger after turning off the vehicle. The next time you start your vehicle, you will then need to manually turn the dash cam back on. We are not responsible for any loss or damage caused by manually turning off the dash cam.

If you have a vehicle that continues to supply power to the cigarette lighter after the vehicle is turned off and have enabled the parking surveillance function. We recommend unplugging the charger to avoid battery drainage, if your vehicle will be parked for long period of time.

Battery usage instructions

The dash cam’s built-in battery is only for finishing and storing videos when the camera is off and providing power when in parking surveillance mode. Please do not use the dash cam without the external power supply or attempt to disassemble the internal battery yourself.

If the dash cam is not used for a long period of time, the battery level may drop to zero. After plugging it into the power supply, it will function normally, although the system time may have been reset to the factory default setting. If this occurs, please reset the time after turning on the camera.

When the battery level is low and you do not have access to an external power supply, you may not be able to turn on the dash cam. If this occurs, you must plug it into an external power supply first, then turn it on and use as normal.

If the battery becomes overheated, becomes deformed, expands, or leaks, you should immediately stop using it and contact our customer service center.
