Main Feature Super Night Vision All of the dashcam channels are enhanced with high performance sensors and WDR technology, enabling the camera to operate in low light conditions at night. With an aperture of F / 2.0 carefully trimmed exposures and ultra-wide Angle lenses, the lens provides a wide range of direction and dynamic range, ensuring sharpne of the final image and night image quality. 24H Parking Monitoring When a collision is detected, the front and rear cameras immediately activate and begin recording, monitoring the car while parked to prevent a hit-and-run. 24 hour parking monitoring requires continuous power supply through the hardwire kit (not provided). Within 30 seconds of a collision or vibration being detected, the camera will immediately turn on and begin recording lock-in video. Motion Detection When the motion detection function is enabled, if the camera detects the movement of the object, the camera would automatically start recording. Loop recording When the storage space is full; Loop recording automatically overwrites the oldest file and records on it. When the g sensor is activated, the front and rear dashboard cameras automatically lock the current lens to prevent overwriting the current lens in the event of a violent jolt/crash, thus protecting critical lenses. MicroSD cards with UHS speed rating U1 cla 10 or higher (excluding TF cards) are supported. G-Sensor and Loop Recording With any collision activated, the g sensor begins recording emergency video, helping you capture evidence in your car's recorder in the event of an accident. When the TF card is full, the oldest unlocked files are automatically overwritten to ensure normal recording.
