How to Read the Memory Card of a Dash Cam?
3 Answers
The method to read the memory card of a dash cam is as follows: First, remove the memory card from the dash cam, then insert it into a card reader connected to a computer, and finally locate and copy the files on the computer. Dash cams are mainly divided into two categories: portable dash cams and aftermarket in-dash DVD dash cams. Portable dash cams can be further categorized into rearview mirror dash cams and data dash cams, which are characterized by good concealment, easy installation, detachability, low cost, and simple operation. Aftermarket in-dash DVD dash cams are mostly used for dedicated vehicles. To read the files from the dash cam, simply remove the memory card and copy the files on the computer.
I've been pondering dash cam issues for years. Reading the memory card is actually quite simple: first, park and turn off the engine to avoid damaging the card or data during operation. Ejecting the card usually involves pushing or pressing a button on the side of the dash cam—different models may vary, so check the manual. Then, find an SD card reader to insert it into; these readers are available at electronics stores for just over ten yuan, or you can use a laptop USB port with a card slot. Once connected to the computer, it will automatically recognize it as a USB drive. Navigate to the file manager to find the video folder—videos are mostly in MP4 or MOV format and can be played by double-clicking. Be careful not to forcibly remove the card, as it may cause file corruption, and remember to safely eject the hardware. When the card is nearly full, it automatically overwrites old videos, so it's advisable to back up the card to your phone or cloud each time you refuel. Poor-quality card readers can damage the card, so opt for branded ones for better performance. Additionally, the card slot tends to accumulate dust, so clean it regularly with compressed air to maintain good contact. If the computer fails to read the card, try switching ports or restarting first; in severe cases, formatting may be necessary, but this will erase all data.
I think handling a dash cam's memory card is no different from tinkering with small gadgets daily. First, turn off the dash cam's power, then gently remove the memory card—don't pull it forcefully. After taking out the card, insert it into a card reader, and plug the USB end of the card reader directly into the computer's side port. Once the computer pops up showing the removable drive, double-click to open the DCIM or related folder inside, and browse to preview the video files. Videos are usually labeled with dates and times for easy searching. If you don't have a card reader, use an OTG cable to connect to your phone—Android users can download a file manager app to handle it. Since the card's space is limited and important clips often get overwritten, save them to a hard drive or cloud storage to avoid loss. Common issues include poor card contact—clean the gold connectors if needed; choose FAT32 or exFAT formats for better compatibility; wireless reading is more convenient but drains battery. Doing this regularly ensures reliable driving safety data and ready evidence when needed.
