Frequently Asked Questions

Which VIOFO dash cams is the RC420 compatible with?
The RC420 is compatible with all A329 platform front units: A329S 1CH, A329S 2CH, A329S 3CH, A329T 2CH, A329T 3CH, A329SW, A329TW, and A329WW series. It connects via the rear coaxial port on the front unit.
Can I add the RC420 to my A329S 1CH to get rear coverage?
Yes. The RC420 is designed for exactly this upgrade. Connect it to the rear port on your A329S 1CH front unit with the included 6-meter coaxial cable. The system automatically recognizes the rear camera — no firmware changes needed. Your A329S 1CH becomes a full 2-channel front + rear system.
What resolution does the RC420 record at?
The RC420 records at 2K (2560x1440) resolution at 30fps with HDR enabled. It uses the Sony STARVIS 2 IMX675 sensor, delivering sharp footage with excellent low-light performance and balanced exposure in high-contrast scenes.
How long is the included cable?
The RC420 comes with a 6-meter (approximately 20 feet) coaxial cable and an adhesive mounting sticker. The 6-meter length is sufficient for most vehicles, routing from the front windshield along the headliner to the rear windshield.
Is the RC420 the same rear camera included with the A329S 2CH?
Yes. The RC420 is the identical rear camera module that ships with the A329S 2CH, A329S 3CH, A329T 2CH, and A329T 3CH packages. It serves as both an upgrade for 1CH owners and a replacement part for multi-channel owners.
Do I need to update firmware after installing the RC420?
No. The RC420 is plug-and-play on all compatible A329 platform front units. Simply connect the coaxial cable, mount the camera, and the front unit detects it automatically. No firmware update or configuration change is required.
