![]() If you would like more information on a particular dash cam and the G sensor functionality, please get in touch. If you have a dash camera and are unfortunate enough to be involved in an accident the last thing you need to worry about is pressing a button or checking the recording has been stored.Īny worthwhile dash cam should have a G sensor- all of the dash cameras featured on Dash Witness have one. ![]() The true benefit of a G sensor in the dash cam environment is the ability for the dash cam to be able to automatically store crucial footage without intervention from the driver. When the train is traveling up a hill, riders typically experience 'positive g-forces'. On a roller coaster, it is caused when the vehicle has velocity on a curve (either vertical or horizontal). The time frame and sensitivity of the G sensor can usually be adjusted. For the roller coaster of the same name, see G Force.G-Force, an abbreviation for 'Gravitational Force', is a force that pulls or pushes on riders. This ensures that the point of impact will be saved into memory for later retrieval. This varies across brands, but the dash cams tend to save footage from 10 seconds before an incident, through to a minute after. When a dash camera detects this change in direction it will automatically switch to ‘event mode’ and save the current segment of footage in a protected section of memory. This could be caused by hard braking, impact from crashing, or even movement when stationary i.e. ![]() In other words, the dash camera will detect a sudden change in direction. A G sensor in a dash cam will monitor the proper acceleration, aka G-Force. They are used in a wide range of devices like smart phones, vehicles and of course, dash cams. A G sensor is commonly referred to as an accelerometer. The relative centrifugal force (RCF) or the g force is the radial force generated by the spinning rotor as expressed relative to the earths gravitational force.
