What does 'no TF card' mean?
2 Answers
When the dash cam does not detect a TF card, it means that no memory card is inserted into the dash cam, causing it to fail to operate normally. TF card, short for Trans-flash Card, serves as the recording medium for dash cams. Since dash cams need to capture footage of the driving route and store videos, they require a TF card. A dash cam without a TF card cannot store recorded videos, thus rendering it inoperable. Relevant information about dash cams is as follows: 1. Introduction: A dash cam is a device that records images, sounds, and other related information during vehicle travel. 2. Function: After installing a dash cam, it can record the entire driving process's video images and sounds, providing evidence for traffic accidents.
When electronic devices display 'No TF card detected', it typically means the device failed to recognize an available memory card. TF cards are those tiny storage cards commonly used in dash cams, action cameras, and even some older mobile phones. My old camera frequently showed this message, making it impossible to save photos after shooting. This issue could be caused by poor contact in the card slot or physical damage to the card itself. Once when I encountered this, simply removing the card, cleaning its metal contacts, and reinserting it solved the problem. If this happens frequently, the card slot's spring contacts might be loose. As a last resort, you'll need to replace the card - just remember to check your device's maximum supported capacity before purchasing to avoid wasting money.
