The VIOFO A329S 3CH is a three-channel dash cam system: a 4K HDR front camera, a 2K 210° fisheye cabin camera and a 2K HDR rear camera, all on Sony STARVIS 2 sensors and all recording HDR at once. The cabin camera is the standout, with a 210° lens that covers the whole interior and reaches past the side windows, IR LEDs for black-and-white night recording, and a mount that rotates 360°. It suits rideshare and taxi drivers, fleet operators and anyone who wants front, cabin and rear evidence from one unit. Its rivals in the three-channel class usually give up resolution on the interior camera or drop HDR on some channels; the A329S keeps 2K HDR on both cabin and rear, and its Low Power Impact Detection parking mode is built to draw far less from the battery than conventional parking modes.

Rated 5 out of 5 from 26 ratings, buyers treat the A329S 3CH as a complete evidence setup and single out the wide cabin view and night footage.
The VIOFO A329S 3CH is a three-camera dash cam system with a 4K HDR front camera, a 2K 210° fisheye cabin camera and a 2K HDR rear camera. All three channels use Sony STARVIS 2 sensors and record at the same time with HDR on every channel.
The cabin camera's 210° fisheye lens captures the whole vehicle interior and extends past the side windows to record activity outside the vehicle. It uses the Sony STARVIS 2 IMX675 sensor at 2K HDR. Built-in infrared LEDs switch it to black-and-white night mode automatically. The camera rotates 360° on its mount, so it can be aimed at the cabin, the rear seats or a side window.
Low Power Impact Detection draws under 40mA at 12.6V. When an impact is detected, all three cameras wake and record in under 2 seconds. Hybrid Parking Mode switches from continuous recording to low-power detection when the battery drops. Full voltage-based control requires the HK6 hardwire kit.
