G-sensor in a Dash Cam


Among the basic features of a dash cam is support for a G-sensor. Its primary function is to instantly record video when the vehicle experiences a collision, preventing the footage from being overwritten.

What is a G-sensor?

A G-sensor (gravity sensor) detects changes in acceleration and converts movement into electrical signals, which are processed by a microprocessor to complete preset functions. For instance, an MP3 player can change songs based on the direction it is shaken.

 

A sensor is an intelligent gravity sensing system that detects the status of a hard drive, automatically positioning the read/write head during a fall to prevent impact and protect the hard drive. This technology is used in dash cams, mobile phones, cameras, and other devices.

 

The Role of the G-Sensor in Dash Cams

In a dash cam, the G-sensor records changes in the vehicle's XYZ axes: the X-axis represents left and right changes, the Y-axis represents forward and backward changes, and the Z-axis represents up and down changes. When the vehicle experiences collisions, shaking, rising, falling, or dropping, the G-sensor converts these movements into electrical signals and sends them to the processor. The processor then analyzes these signals, locks, and saves the relevant video to prevent it from being overwritten. When the acceleration value returns to normal, the dash cam resumes normal operation.

 

A high-quality dash cam should have a G-sensor to record sudden events such as emergency braking or collisions, automatically recording and force-saving critical footage to avoid being overwritten by loop recording. This helps reconstruct the accident scene and determine the truth and responsibility. Therefore, when choosing a dash cam, it is essential to select a product with a G-sensor.
