FAQ

The speed of a memory card affects read/write performance. Choose based on the following markings:

Class 10 (C10): Minimum 10MB/s, it is suitable for daily base use.
UHS Speed Class 1 (U1) or 3 (U3): Minimum 10MB/s , it is suitable for Full HD recording
Video Speed Class (V30, V60, V90):  Minimum 30MB/s , it is suitable for high-definition video recording

💡Please choose U3 or V30 grade above memory card for camera or 4K recording.

The reason why the storage capacity displayed on a computer is always less than the actual capacity is due tobelow :

1. The difference in calculation methods. Computers use a binary system for storage calculation, where 1GB is equal to 1024 × 1024 × 1024 = 1,073,741,824 bytes (since 1024 is 2 to the power of 10). 
2. Additionally, SP reserves 3% to 5% of the total capacity for device firmware and data storage management, which helps to improve the product's reliability and lifespan. 

Therefore, a storage device labeled as 64GB actually has a capacity of 64,000,000,000 bytes. When this is converted to the binary system used by the computer, it becomes:
64,000,000,000 ÷ 1,073,741,824 ≈ 57GB~59GB.

1. Please make sure the specification of the Memory Card is compatible with your device.
   -SDXC Memory Card can only be used on a device that supports SDXC.
   -SDHC Memory Card can be used on a device that supports SDHC and SDXC.
   -SD Memory Card can be used on a device that supports SD, SDHC and SDXC. 2. Please use our compatibility chart to confirm 
2. Memory Card compatibility with your device

Here are some common reasons why your memory card might not be readable and what you can do to troubleshoot the issue:

1. Check for Physical Damage: Inspect the memory card for any visible physical damage like cracks, bends, or warping.
2. Ensure Correct Insertion: Make sure the memory card is inserted correctly and fully into the device.
3.  Test with Other Devices: Try inserting the memory card into another device (like a computer or another phone) to see if it can be read there. This helps determine if the issue is with the card itself or the original device.
4.  Clean the golden finger of memory card: The golden finger of  the memory card might be oxidized or dirty. Gently wipe the golden fingers with a dry cloth.
5.  Perform Error Checking and Repair: Use a computer built-in tool to check  and repair any errors on the memory card.
⚠ Important: If you've tested the memory card with other devices and it still can't be read, it might require replacement.

1. If it is SD card, please ensure the Lock switch of Memory Card is set to the "Writeable" position.
2. Please try to format memory cards on different devices, for example, cameras or computers.
3. Use the following (SD formatter: https://www.sdcard.org/cht/downloads/formatter_4) to format the card.  After formatting, please put the card back into the device to make sure it is working.  If a "not format error" occurs, the card is confirmed to be damaged. 

Choosing the suitable memory card for your dashcam or surveillance system is crucial for reliable performance. Here's what you should look for:

Opt for High Endurance Cards: It's highly recommended to choose high-endurance memory cards specifically designed for dashcams and surveillance cameras. These cards, like the "Golden Series High Endurance microSD," are built to withstand the continuous read/write cycles required by these devices.

Check Speed Class: Ensure the memory card has a speed class of Class 10, UHS-I, or higher. This guarantees smooth video recording without dropped frames or interruptions.

Match Device Capacity: Select a memory card that is compatible with your device's supported capacity. Using a card that exceeds the maximum supported capacity of your dashcam or surveillance camera can lead to compatibility issues.

Avoid Standard Consumer Cards: Do not use general-purpose memory cards designed for mobile phones or digital cameras. Devices with high write-cycle recording demands, like dashcams, require cards with much greater durability.

Please refer to the chart below to see the approximat numbers of several data types that can be stored in the memory card.

When you're using a memory card with your dashcam for the first time, here's how to set it up properly:

Format in the Dashcam: It's highly recommended to format the memory card directly within your dashcam's settings the first time you use it. This ensures optimal compatibility between the card and your specific dashcam.

Confirm Insertion and Recognition: Make sure the memory card is inserted correctly into the dashcam, and then confirm that the device recognizes it properly.

Configure Recording Settings: Set up your preferred recording mode and activate the loop recording function. Loop recording is crucial for dashcams as it automatically overwrites the oldest footage when the card is full.

Regular Formatting: To maintain stable recording performance, it's necessary to  format your memory card regularly, this helps prevent data corruption and ensures smooth operation over time.

1. After extended use, memory card storage blocks may become fragmented due to frequent writing, which can impact read/write speeds.

2. It is recommended to back up your data regularly and format the memory card periodically to maintain optimal performance.

3. When the card is nearly full, read/write speed may decrease. Keeping some free space can help improve performance.

4. Using a low-speed or incompatible memory card in devices with high write demands (e.g., dashcams, surveillance cameras) may result in performance drops. It is advisable to use high-endurance memory cards for such purposes.

It's recommended to format them periodically to maintain stable performance, especially:

1. If you experience slow reading speeds or are unable to access files.
2. If  you used memory cards in dashcams or surveillance cameras, it's advisable to format every 1-2 months to prevent data fragmentation from affecting read/write speeds.

💡 Always back up important data before formatting to avoid accidental deletion!

Memory cards can be used across different devices, but compatibility issues may arise. It is recommended to:

1. Format the card in the device such as a camera or dashcam before using.
2. Avoid frequent switching between devices (e.g., camera ⇄ smartphone), as this may cause file corruption.
💡 Different devices may use different file systems. If issues occur, reformat the card in the intended device!
