Which 3-channel configuration should I choose?

For rideshare and personal vehicles: front + standard rear + interior cabin. For trucks and SUVs without a clear rear windshield: front + waterproof rear + interior cabin. For maximum evidence with plate capture: front + telephoto + interior cabin or front + telephoto + waterproof rear. For large trucks and construction vehicles: front + dual waterproof side cameras.

Can I mix and match different camera modules?

Yes. VIOFO's modular architecture lets you connect any compatible camera combination to the front unit. You can start with a 1-channel or 2-channel setup and add a third camera at any time — standard rear, waterproof rear, interior, or telephoto — without hardware replacement.

What is the highest resolution available on a VIOFO 3-channel system?

The A329S platform records 4K (3840×2160) at 60fps on the front camera with 2K (2560×1440) on the second and third cameras — all simultaneously with HDR processing on every channel. This is the highest resolution 3-channel performance available from any dash cam manufacturer.

How does the interior cabin camera work at night?

The interior camera includes infrared (IR) LEDs that automatically activate in low-light conditions, switching to a high-contrast black-and-white mode that clearly captures faces, movements, and cabin details in complete darkness — without any visible light that might distract passengers or the driver. The 210° fisheye lens covers the entire cabin edge to edge.

How much storage does a 3-channel system need?

Recording three channels simultaneously uses more storage than single or dual setups. Most VIOFO 3-channel systems support microSD cards up to 512GB. The A329S platform also supports external SSD storage up to 4TB via USB 3.0, providing over three weeks of continuous 3-channel recording — ideal for fleet operations and long-haul trucking.

What makes VIOFO's 3-channel design different from competitors?

Most competing 3-channel systems integrate all cameras into a single bulky unit, forcing a single mounting point that compromises angles. VIOFO uses separate, compact camera modules connected by slim coaxial cables — each independently positioned for optimal coverage. More importantly, VIOFO is the only manufacturer offering this many 3-channel configurations: standard rear, waterproof rear, telephoto, interior, and dual waterproof — all interchangeable on the same platform.
