If you mainly commute and have a limited budget, a single-camera dash cam is a great entry-level option.
For most drivers, a dual-camera dash cam is more practical as it provides complete front and rear coverage.
If you’re a professional driver or want to record everything inside and outside your vehicle — especially during family trips — then investing in a 3-channel camera dash cam is definitely worth it.

Pro Tip:

No matter which type you choose, look for models with loop recording, a G-sensor for emergency file locking, and support for high-endurance memory cards.
Parking mode and GPS tracking are also valuable features to consider for extra peace of mind!
