G-sensors, also known as accelerometers, are an important feature in modern dashcams.
A G-sensor is a type of accelerometer that measures changes in acceleration along three axes: X, Y, and Z.
It detects sudden changes in movement and translates them into electrical signals, which can be used to trigger an event, such as the activation of a dashcam's recording function, providing valuable evidence in the event of an accident or collision.
Vantrue, a leading manufacturer of dashcams, incorporates G-sensors into its E-series dashcams to provide added security and accountability for drivers.
The unit of measurement used for acceleration is g-force, with one g-force being the force of Earth's gravity on a stationary object.
G-sensors used in dashcams are typically MEMS devices, which use tiny moving parts to measure acceleration. MEMS G-sensors are highly accurate and sensitive, making them ideal for detecting even small changes in movement. In addition, some G-sensors can also detect changes in rotation, providing a more complete picture of the motion of a vehicle.
Applications in Dashcams
Impact Detection: G-sensors in dashcams can detect sudden changes in acceleration, which are typically indicative of an impact or collision. When an impact is detected, the dashcam will automatically save the footage of the incident, providing valuable evidence for insurance claims and legal disputes.
Motion Detection: In addition to impact detection, G-sensors can also be used to detect motion when the vehicle is parked. This is particularly useful for monitoring the car while it is parked, as the dashcam can alert the driver if any motion is detected and save footage of the incident.
Hard Braking Detection: G-sensors can also detect hard braking events, which are typically indicative of unsafe driving behaviors. Dashcams can use this information to provide feedback to drivers, such as alerts or notifications, to help them improve their driving habits.
Rapid Acceleration Detection: G-sensors can also detect rapid acceleration events, which can be used to provide feedback to drivers on their driving habits. Dashcams can provide alerts or notifications when rapid acceleration events are detected, which can help drivers to drive more safely and efficiently.
Lane Departure Warning: G-sensors can also be used to provide lane departure warnings to drivers. By detecting changes in the vehicle's position and acceleration, dashcams can alert drivers if they are drifting out of their lane or are at risk of colliding with other vehicles.
Low Light Recording: Some dashcams use G-sensors to automatically adjust the camera settings based on the lighting conditions. This ensures that the footage captured by the dashcam is clear and visible, even in low light or nighttime driving conditions.
Driver Assistance: G-sensors can also be used to provide driver assistance features, such as forward collision warnings, blind spot monitoring, and adaptive cruise control. These features use G-sensor data to detect potential hazards and provide alerts or interventions to help drivers avoid accidents.
Advantages of G-Sensors
The main advantage of G-sensors in dashcams is their ability to automatically trigger recording in the event of an accident or collision. This ensures that footage of the incident is saved, even if the driver is unable to do so manually. Once activated, the G-Sensor triggers the appearance of a padlock at the center of the screen, indicating to the driver that the file is being secured. This feature provides drivers with the added reassurance that their critical footage is being safely stored and can be reviewed at a later time without the need to immediately remove the Dash Cam after an incident has occurred. G-sensors can also help protect drivers from false insurance claims or legal disputes, providing clear evidence of what happened on the road.
Applications in E-series Dashcams
Vantrue's E-series dashcams incorporate advanced G-sensor technology to provide drivers with added security and accountability on the road. Here are some key features of the E-series dashcams:
Three-axis G-sensor: The E-series dashcams feature a three-axis G-sensor that can detect impacts and collisions from all directions. This ensures that footage of the incident is saved, even if the vehicle is hit from the side or rear.
Adjustable sensitivity: The sensitivity of the G-sensor can be adjusted to suit the driver's needs. This allows the dashcam to detect both minor and major incidents, providing flexibility and customization for different driving scenarios. For Vantrue E3, you can select the level of G-sensor you require, then you can set 3 directions (Front/Rear + Right/Left + Up/Down). The G-sensor value in each direction can be selected as 1 /2/3/4/5/Off. The higher the sensitivity level, the easier it is to trigger event recording. G-sensor is most sensitive when set to 5.
Loop recording: The E-series dashcams use loop recording to continuously record footage, overwriting the oldest files as new ones are created. This ensures that the dashcam always has the latest footage available, without taking up too much memory on the device.
Parking mode: The E-series dashcams feature a parking mode that uses the G-sensor to detect impacts or bumps while the vehicle is parked. When an incident is caught, the dashcam automatically saves footage of the event, providing valuable evidence in the event of a hit-and-run or vandalism.
G-sensors are a critical feature in modern dashcams, providing automatic collision detection and helping to protect drivers from false claims or legal disputes. Vantrue's E-series dashcams incorporate advanced G-sensor technology, providing added security and accountability for drivers on the road. With adjustable sensitivity, loop recording, and parking mode features, the E-series dashcams offer a range of functionalities to suit different driving scenarios and needs. The G-sensor technology in E-series dashcams ensures that drivers have reliable evidence in the event of an incident, providing peace of mind and protection on the road.
