FAQs
Which dashcam offers better parking mode for Canadian winters?
The VIOFO A329S has an edge in parking mode performance, featuring buffered pre-event recording triggered by motion and impact sensors. It also supports lower operating temperatures (down to -20°C), which is advantageous in harsher Canadian winters. However, the Nexus 4S also provides solid parking mode functionality and operates reliably to -10°C, suitable for less extreme cold conditions.
Can both dashcams record front and rear simultaneously in 4K?
Both the Nexus 4S and the VIOFO A329S record front and rear footage simultaneously, but only the front camera records in 4K resolution. The Nexus 4S records rear footage at 1440p, while the VIOFO A329S records rear video at 1080p. If 4K rear recording is essential, neither model offers this currently, but both provide high-quality video for comprehensive coverage.
