Can You Upgrade the VIOFO A329S 1CH to a 2-Channel or 3-Channel System?

The VIOFO A329S has quickly become a favourite for drivers seeking 4K 60fps recording. Whether you want to add a 2K Telephoto lens for catching licence plates at a distance or an Interior Cabin camera for rideshare security, the A329S is designed for growth.

The Modular Advantage of the A329S

Unlike many dash cams that require you to buy an entirely new kit for more cameras, the VIOFO A329S uses a unified main body. The expansion ports are already built into the side of your device, waiting for an upgrade.

What You Can Add to Your Setup

• The RTC-420 (Telephoto Lens): Perfect for capturing distant licence plates with 2K resolution.
• The RCC-360 (Interior/Cabin Lens): A 2K fisheye with IR for recording the inside of the vehicle in total darkness.
• The RC-420 (Standard Rear Lens): A classic 2K rear-facing camera for monitoring traffic behind you.

Expansion FAQ

If I bought the Cabin 2CH, can I switch the cabin camera to a Telephoto lens?
Absolutely! The ports are flexible, allowing you to swap modules as your driving needs change.

Can I run both a Cabin and Telephoto lens with no rear camera?
Yes! VIOFO's open platform means you aren't locked into specific configurations - a 10/10 for versatility.

How to Perform the Upgrade

1. Plug and Play Hardware: Connect your new module to the REAR or INT port on the main A329S unit using the provided cables.
2. Firmware Adjustment: Update to the firmware version that matches your new setup to unlock optimized menu settings and display layouts.

Pro Tip: Moving from single-channel to three channels puts a heavy load on your memory card. Consider using the A329S's External SSD support via USB-C to ensure you never drop a frame.
