Should the G-sensor of the dash cam be turned on?

The G-sensor of the dash cam can be turned on, but it should be set to the low option, and the memory card should be formatted regularly to prevent the memory card from storing too many videos that cannot be overwritten, which would reduce the available space for loop recording. The G-sensor, also known as impact storage, works by detecting when the value from the gravity sensor exceeds the set threshold, indicating a collision. When this happens, the dash cam's CPU marks the current video segment as protected from deletion, enabling automatic storage upon collision. Generally, dash cams offer three sensitivity options: high, medium, and low. When frequently accelerating, decelerating, or driving on bumpy roads, if the dash cam is set to high or medium sensitivity, almost all videos will be saved in a read-only state, meaning they will not be overwritten.

I think the G-sensor on the dash cam is absolutely essential to turn on. It's a practical feature that automatically detects collisions or sudden braking and then locks the footage. I've used it several times over the years—once in a rear-end accident, it saved the crucial clip, saving me the hassle of manual operation and providing direct evidence for insurance claims. However, the sensitivity should be set to a moderate level—not too high—otherwise, it might trigger falsely over speed bumps or small potholes, wasting storage space and draining the battery. I recommend setting it to medium sensitivity, regularly cleaning the memory card, and backing up files. This way, it's both safe and hassle-free. After all, driving safety comes first, and having this feature is like having an extra helper—don't lose the big picture over minor issues.

As a long-haul driver, I recommend turning on the G-sensor because it automatically saves accident footage without manual intervention. Once, when I had to brake suddenly to avoid a vehicle on the highway, the recording was immediately protected and not overwritten, which was very practical. However, be mindful of false alarms—if it's too sensitive and triggers over bumps, it can waste storage space, so just lower the sensitivity a bit. I also pay attention to power consumption and SD card costs, making it a habit to check and clear old files monthly. Overall, the benefits outweigh the drawbacks, especially in urban areas where unexpected situations are common—turning it on adds an extra layer of security.

My personal preference is to always drive with the G-sensor enabled—it's simple, convenient, and safe. For instance, it automatically locks and saves video footage during collisions or sudden stops, sparing me the hassle of manually searching for evidence afterward. Just make sure not to set the sensitivity too high to avoid excessive battery drain from false recordings. Regularly backing up data from the memory card prevents it from getting full. I’ve found it worry-free over the years, giving me more peace of mind with less hassle.

I always keep the G-sensor on during my daily commute, which helped capture that moment when someone changed lanes and scraped my car, automatically locking the footage. This feature is useful in emergencies, but if not set properly, it can trigger falsely—like recording over speed bumps—filling up the memory card. I adjusted the sensitivity to a mid-range to avoid over-sensitivity and make sure to check the storage weekly, deleting old files to keep it running smoothly. For frequent drivers, turning on the G-sensor is a wise choice to stay prepared for the unexpected.

The G-sensor should remain activated as it automatically locks accident footage to provide reliable evidence. The downside is potential false alarms and resource consumption, so adjusting sensitivity to avoid overly high settings is advisable. My experience proves that regularly managing the memory card to prevent clogging is crucial—make it a habit to back up data monthly. This is vital for driving safety, and the benefits of enabling the G-sensor far outweigh the drawbacks.
