A229 Pro 2CH vs 3CH Specs

camera configuration

Edge: VIOFO A229 Pro 3CH 4K Dash Cam

The VIOFO A229 Pro 4K Front 2K Rear covers just the front and rear exterior views. This setup provides comprehensive coverage of the road ahead and the vehicle behind. The VIOFO A229 Pro 3CH 4K Dash Cam adds a third channel for the cabin interior. This inside camera records at 1080P resolution. It uses a separate STARVIS sensor and infrared LEDs for low-light visibility inside the car. This makes the 3CH model better for rideshare drivers or parents monitoring back seats. You choose based on whether interior monitoring is necessary for your daily driving needs.
