What does it mean when a dash cam has no TF card?
2 Answers
A dash cam not detecting a TF card means that there is no memory card inserted into the dash cam, preventing it from functioning properly. Specific details are as follows: 1. TF card: The full name of a TF card is Trans-flash Card, and its role is to serve as the recording medium for the dash cam. Since dash cams need to record footage of the driving route and store videos, they require a TF card. Without a TF card, the dash cam cannot store recorded videos and thus cannot operate. 2. Correct camera installation position: Dash cams have front and rear cameras. The front camera is usually installed on the rearview mirror, while the rear camera is typically placed in the center of the rear windshield. Only when the cameras are correctly positioned can they display effective footage.
A dash cam without a TF card means no microSD card is inserted. This thing is essentially the storage hard drive of the device. Without it, the device cannot save video recordings. Every time you start the car, the dash cam checks if the card slot is empty. If there's no card, the indicator light might flash or display an error code, video loop recording won't work, and the emergency event protection feature will also fail, severely impacting daily monitoring. It's recommended to use a Class 10 or higher 64GB capacity card, which is more reliable in high-temperature environments. Avoid using small-capacity cards to prevent insufficient storage space. Regularly check the card slot to ensure it's firmly inserted, otherwise, you might lose crucial evidence in emergencies.
