When it comes to protecting your vehicle, a dash cam is one of the smartest investments you can make. But not all dash cams are built the same. If you want full protection both while driving and while parked, you need a dash cam with a G-sensor and parking monitor. These two features work together to safeguard your car against collisions, hit-and-runs, and vandalism—whether you’re on the road or away from your vehicle.
In this guide, we’ll break down what these features do, why they matter, and the best dash cams with G-sensor and parking monitor you can buy.
Best Dash Cam with G-Sensor and Parking Monitor: Top Picks
Why Choose a Dash Cam with G-Sensor and Parking Monitor?
- G-Sensor (Gravity Sensor): This built-in sensor detects sudden impacts, hard braking, or sharp turns. When triggered, the dash cam automatically locks and saves the video footage so it can’t be overwritten. This is crucial in case of accidents.
- Parking Monitor: This feature keeps your car protected even when the engine is off. If your vehicle is bumped or someone tries to tamper with it, the dash cam records the incident. Some models use motion detection, while others use time-lapse or impact-based recording.
Together, these features give you 24/7 surveillance—peace of mind while driving and parking.
