G-sensor in the DVR-what is it?

The term G-sensor (accelerometer) is familiar not only to car owners, because this device is present in many modern devices-tablets, phones, recorders, etc. Its main purpose is to form a special signal, focusing on its position relative to the Earth's gravitational field, which is already noticeable by the capital letter in the name of the sensor-Gravitation.

Why do you need a G-sensor?

Timely response to changes in vehicle speed is the main task of the G-sensor in the DVR. Contrary to the mistaken opinion of drivers who mistake the device for a shock sensor used in car alarms.

The principle of operation of the G-sensor is based on transmitting a signal to the microprocessor that controls the modes of the DVR, implementing one of the functions:

fixing and storing in memory the moment of a sharp change in the speed of movement;
moving footage to a "black box" that protects information from being overwritten or deleted;
emergency activation of the recording of the recorder.

G-sensor in DVR

Piezoelectric. In the structure itself, there is an inertial element (ball), which is located on a piezo suspension. At the moment of acceleration of the car, the piezoelectric element detects dynamics by creating an electrical signal, which is then sent to the G-sensor in the recorder. The sensor sends a "request" to record a change in the pace of movement.
Magnetoresistive. The magnet is the basis of the inertial element, and the resistance of the magnetic field determines the movement of the vehicle.

What is the G-sensor in the DVR?

To quickly assess the importance of the G-sensor in the car recorder, visualization of only one situation will help-you left the car in the parking lot at night, and in the morning a surprise awaits-a new scratch. Pleasant little. However, the G-sensor could detect movement and activate recording to remember the culprit's face.

How to set up the G-sensor on the dash cam?

The G-sensor lends itself to adjusting certain characteristics, namely:

sensitivity level;
time to write to the black box;
current date and time.

G-sensor sensitivity adjustment

You can change the sensitivity level of the G-sensor directly in the main menu of the recorder, focusing on one of these scales:

from 1 to 10;
2g (maximum) -8g.

Remember that choosing the maximum sensitivity level of the G-sensor, it will trigger on:

pits and poor road surface;
minor physical impact on the body;
abrupt start or brake;
daring maneuvers.

An additional consequence of high sensitivity will be a full memory of the indelible area, which increases the risk of a lack of free space at the time of the accident.

Additional recommendations for adjusting the G-sensor

Considering the question-"how to set up the G-sensor on the DVR?", you should pay attention to the choice of timing for shooting an unforeseen incident (before and after) in the "black box". The menu offers the owner 10-60 seconds, but 30 seconds will be enough to fully understand the situation.
