What is the difference between this 3-channel setup and the waterproof rear version?

This collection uses a standard rear camera that mounts inside the vehicle behind the rear windshield. The waterproof rear version mounts on the vehicle's exterior with IP67 waterproof protection. Choose the standard interior-mount for sedans and vehicles with a clear rear windshield; choose waterproof for trucks, SUVs with tinted glass, or any vehicle where the rear camera needs external mounting.

How much storage does a 3-channel system need?

Recording three channels simultaneously uses more storage than single or dual setups. Most models support microSD cards up to 512GB. The A329S 3CH 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 trips.

Can I position the interior camera to face passengers?

Yes. VIOFO's interior camera module features a 360° rotatable mount, so you can angle it toward the back seat for rideshare use, toward the driver's side for fleet monitoring, or any position in between. The A329S interior camera's 210° fisheye lens captures the entire cabin regardless of angle.

Which 3-channel model should I choose?

The A329S 3CH is the flagship — 4K 60fps front, 2K interior with 210° fisheye, 2K rear, Wi-Fi 6, SSD support. The A229 Pro 3CH offers excellent 4K front + 2K rear + 1080P interior at a lower price. The A229 Plus 3CH is the value pick with 2K on all three channels and Sony STARVIS 2 sensors throughout.

Does parking mode work on all three channels?

Yes. In parking mode, all three cameras remain active and trigger recording when motion or impact is detected. Buffered recording captures up to 15 seconds before the event, ensuring nothing is missed. A hardwire kit (sold separately) provides constant low-voltage power for 24/7 parking surveillance.
