Can a dash cam record without a memory card?
2 Answers
A dash cam cannot record without a memory card, as it does not have built-in memory and relies on memory card expansion or a mobile digital hard drive. The memory card slot on a dash cam is typically located on the top or sides of the device. A dash cam consists of a microprocessor, data storage, real-time clock, display, lens module, operation keys, printer, data communication interface, speed sensor, and data analysis software. The functions of a dash cam are: 1. It can record video and audio of the entire driving process, providing evidence for traffic accidents; 2. For car owners who enjoy self-driving tours, it can be used to record the scenery along the way.
The core function of a dash cam is video recording and storage. Without a storage medium, continuous recording is basically impossible. I've seen many car owners assume that the dash cam comes with built-in storage, only to find out during an accident that no memory card was inserted, resulting in the loss of critical footage. Most entry-level products rely entirely on memory cards as the storage medium, as manufacturers omit internal storage modules to control costs. Even some high-end models with a few GB of built-in storage can only save a few minutes of footage, which is far from sufficient for daily use. Some users consider using WiFi direct connection to store videos on their smartphones, but this method is prone to disconnections and consumes significant power, leading to a poor user experience. Therefore, inserting a moderately sized, high-speed memory card is the most reliable solution to ensure that crucial evidence is retained when needed.
