Viofo A329S Dash Cam 2CH ($400)
- 4K at 60fps up front doubles the frames available to pause on a crossing vehicle or a plate compared with the 30fps field
- STARVIS 2 sensors on both channels, with HDR on both, instead of reserving the current sensor generation for the front alone
- External SSD support to 4TB alongside microSD to 512GB ends the loop-overwrite pressure that three-figure card limits impose on high-mileage drivers
- The 4K 60fps mode and HDR do not run together: HDR recording is a 4K 30fps mode, so the buyer chooses smoothness or HDR balance per trip, not both at once
- No memory card is included and parking surveillance needs a separate hardwire kit, so the fitted cost for a parked-car household is above the camera price
- The external SSD route needs Viofo's dedicated cable and a compatible drive; it is an extra purchase, not storage in the box
The A329S in its two-channel form is ranked first on documented imaging: a front camera recording 4K at up to 60 frames per second from the Sony STARVIS 2 IMX678 sensor — with HDR available at 4K 30fps — and a rear camera recording 2K from the second STARVIS 2 sensor, the IMX675, also with HDR. Wi-Fi 6 moves clips at up to about 30 MB/s by the maker's figure, GPS is built in, and storage runs from microSD up to 512GB to an external SSD up to 4TB on Viofo's dedicated cable. Viofo publishes an 18-month warranty for the model. Owners rate the Amazon listing about 4.5 stars across roughly 145 ratings on the Canadian marketplace capture of the same ASIN, flagged in the dossier; the US aggregate could not be isolated in this pass, so that figure is recorded as a compilation lead, not substituted silently.
Viofo is a dash-cam specialist selling in the US through Viofo.com and Amazon as VIOFO LTD. Viofo's own A329 Pro and A229 Pro manual publishes support at [email protected]; Viofo publishes no US support phone for the model, so that field is blank.
