- **最适合:** It records with built-in LTE and supports Parking Mode, but the key spec tied to recording sound is the continuous loop recording on microSD while voice guidance is built-in with a built-in speaker, keeping the main audio path handled through the cam rather than any separate high-noise accessory.
