VIOFO A329S 3CH
VIOFO's flagship three-channel recorder puts a Sony STARVIS 2 sensor on every lens — 4K front, 2K cabin with a 210-degree view, and 2K rear — and adds Wi-Fi 6 plus support for an external SSD up to 4TB, enough for weeks of continuous long-haul footage.

Our Verdict
The most complete three-channel setup here: every channel — 4K front, 2K cabin, and 2K rear — uses a Sony STARVIS 2 sensor, so plates, faces, and the cab are all captured sharply rather than trading resolution between lenses. Wi-Fi 6 and support for an external SSD up to 4TB let it record weeks of continuous three-channel footage before overwriting, which matters on long hauls. It edges the Vantrue N4 Pro S on cabin and rear resolution and on storage headroom; its price is the only real reason to look elsewhere.

Alternatives to Consider
Vantrue N4 Pro S
Vantrue
Marketed and built for trucks, the N4 Pro S carries an IP67 dust and water rating on its camera hardware and pairs 4K front and 2.5K rear video with a 1080p infrared interior lens, so the cab stays visible even in the dark.
VIOFO A229 Pro 3CH
VIOFO
The value three-channel pick: 4K front, 2K rear, and 1080p interior coverage on Sony STARVIS 2 sensors for around $310, with an included CPL filter, 5GHz Wi-Fi, GPS, and 24-hour parking mode.
Vantrue N5
Vantrue
The only four-channel option here, the N5 records the front, front cabin, rear cabin, and road behind at once for genuine 360-degree coverage, with two infrared interior lenses that keep the cab and sleeper visible in the dark.
Redtiger F7NA
Redtiger
A genuine budget standout: true 4K front recording on a Sony STARVIS 2 IMX678 sensor plus a 1080p rear camera, 5GHz Wi-Fi, and GPS for around $140 — a lot of front-and-rear capability for company drivers who don't need a cabin lens.
