G-Sensor Car Cameras: How Do They Work?

A G-sensor, or G-shock sensor, is an essential feature of a car dash camera. It works by detecting any movement to your car before locking and protecting a recorded video file from being deleted. This means that footage of someone reversing into your car will be kept and preserved even if you forget to upload the event. The G-sensor will also keep working when the engine is off, ensuring that video recording will activate and record in case your parked car is hit. The 'G' in the G-sensor refers to gravity, and the sensitivity option is configured with units of gravity, where 1G is equivalent to 9.81m/s². When the G-sensor is set to the lowest value, it takes just the slightest knock to activate, while setting it to the highest setting requires quite a bit more force to activate.

G-sensor automatically locks files in the event of a collision

A G-sensor, or gravity sensor, in a car camera is a feature that automatically locks and saves footage in the event of a collision. This ensures that important footage before, during, and after an incident is not overwritten and can be reviewed later or used as evidence for insurance claims.

The G-sensor is an accelerometer that measures G-forces, or forces of acceleration, acting on a vehicle. When the sensor detects a significant change in motion or a force beyond a certain threshold, it triggers the camera to lock the current video file. This locked file is then stored in a separate folder, preventing it from being overwritten when the storage space becomes full.

The sensitivity of the G-sensor can often be adjusted in the camera settings, allowing users to fine-tune the sensor to avoid false triggers from minor impacts or bumpy roads. A higher sensitivity setting will result in the sensor being triggered by smaller forces, while a lower setting will require a stronger impact to activate the sensor.

It is important to note that the G-sensor only locks files when the camera is already recording. Additionally, some cameras may have specific settings or requirements for the G-sensor to function, such as enabling parking mode.

By automatically securing crucial footage during unexpected events, a G-sensor-equipped car camera provides an additional layer of protection and peace of mind for drivers.

It can detect a change in direction, e.g. hard braking or impact

A G-sensor, or gravity sensor, is an integral part of a car camera's safety features. It can detect a change in direction, such as hard braking or impact, and automatically lock and save the footage for future reference. This is especially useful in the event of an accident, as it provides valuable evidence of what happened.

The G-sensor's sensitivity can be adjusted to suit different driving conditions. For example, when driving on uneven terrain, you can lower the sensitivity to avoid unnecessary triggers due to frequent jolts and vibrations. On the other hand, when parking in an area with a high risk of vandalism, increasing the sensitivity will ensure that even minor scratches or bumps are recorded.

The G-sensor's ability to detect changes in motion or orientation is based on its measurement of the acceleration due to gravity. This is converted into a piezoelectric effect, where pressure and stress generate energy, which is then transformed into electrical voltage, providing velocity and orientation data.

The automatic locking and saving of footage by the G-sensor ensures that crucial moments leading up to an incident are not lost. This feature is especially valuable when coupled with high-resolution cameras, as it enables the identification of license plates or individuals in the event of an accident or hit-and-run.

Overall, the G-sensor's functionality enhances road safety and provides drivers with peace of mind, knowing that their car camera is equipped to handle unexpected events and capture vital footage.

The G-sensor can be set to different levels of sensitivity

The G-sensor in a car camera is a built-in accelerometer that detects sudden impacts and vibrations and signals the camera to start recording. The G-sensor can be set to different levels of sensitivity, which determine the amount of force needed to trigger the sensor and lock the file from being overwritten. The sensitivity settings are usually high, medium, and low, with medium being the default setting.

If the G-sensor sensitivity is set to high, even slight vibrations or impacts, such as potholes, door closing, or abrupt braking, will be recorded. This results in a lot of unnecessary footage being recorded and saved, taking up valuable storage space. On the other hand, setting the sensitivity to low means that only larger impacts, such as collisions and accidents, will be recorded. This ensures that only important footage is captured, and the dashcam is not triggered by minor events.

It is important to find the right balance when setting the G-sensor sensitivity. If the sensitivity is too high, the sensor may be triggered by normal driving events, such as speed bumps or potholes, resulting in a memory card filled with locked files of non-critical events. On the other hand, if the sensitivity is too low, the sensor may not capture all the necessary details of an accident or collision.

The ideal G-sensor sensitivity setting depends on various factors, including the type of vehicle, the condition of the roads, and the suspension system. It is recommended to test the G-sensor at different sensitivity levels and observe its response to different driving conditions. For example, you can test the G-sensor at the roughest part of your usual driving route and see if it gets activated. If there is no activation, you can try increasing the sensitivity to "High". If there are too many activations on smaller bumps, you can decrease the sensitivity to "Low".

By adjusting the G-sensor sensitivity to the appropriate level, you can ensure that your dashcam captures crucial footage while avoiding unnecessary recordings. This helps to maintain sufficient storage space and makes it easier to retrieve important events when needed.

It can also detect movement when the car is stationary

A G-sensor, or gravity sensor, is an integral safety feature in modern cars. It can detect the slightest movement in or around your stationary car, such as someone shaking or hitting your vehicle. This is especially useful when your car is parked, and you are not there to witness any mishaps.

The G-sensor's ability to detect movement is not limited to when the car is stationary. It also detects sudden changes in motion or orientation when the car is in motion. For instance, if you are driving and have to brake suddenly, the G-sensor will detect this abrupt change in motion and spring into action.

The G-sensor is also useful in the unfortunate event of a car accident. It automatically locks and saves footage, preserving irreplaceable evidence without requiring any intervention from the driver. This is especially helpful if the driver is unconscious or unable to act after the accident.

The G-sensor's sensitivity can usually be adjusted based on driving conditions. For example, if you are driving on an uneven, off-road terrain with frequent jolts and vibrations, you can set the G-sensor's sensitivity to low to avoid unnecessary triggering of the dash camera. Conversely, if you are parking your car in an area with a high risk of vandalism, you can set the sensitivity to high to ensure that even the slightest scratch or bump is recorded.

The G-sensor's ability to detect movement and trigger emergency recording mode makes it an invaluable tool for car safety and accident investigation.

The G-sensor can be set to different levels of precision, from 2G to 5G

The G-sensor in a car camera is a highly beneficial feature that can be used to automatically lock and protect recorded video files from being deleted. This is particularly useful in the event of a collision, as the footage will be preserved even if you forget to upload it elsewhere. The G-sensor can be set to different levels of precision, from 2G to 5G, which determines the sensitivity of the sensor and the amount of force required to activate it.

The 'G' in G-sensor refers to gravity, and 1G is equivalent to the force of Earth's gravity, or 9.81m/s². When a car with a G-sensor is at rest, the reading will be 1G. A reading of 2G would indicate a force twice that of Earth's gravity, which could be triggered by a slight movement like driving over a speed bump. A higher reading of 5G would require a much greater force, such as crashing into another car.

By adjusting the G-sensor precision, you can control how sensitive the sensor is to impacts and movements. A lower setting will result in the sensor being triggered by even slight knocks or bumpy terrain, while a higher setting will require a more forceful impact to activate. This allows you to customise the G-sensor to avoid unnecessary triggers and ensure it captures only the most important events.

The G-sensor is an essential feature for any car camera, providing an additional layer of protection and ensuring that crucial footage is automatically secured during unexpected or significant events on the road. It offers peace of mind, knowing that your car and footage are kept safe, whether you're driving or parked.
