Garmin Dash Cam Tandem vs Vantrue N4: Dual-Channel Dashcam Comparison

The Vantrue N4 records front at 4K, rear at 1080p, and interior at 1080p — three channels of high-resolution video. The Garmin Tandem records front at 1440p and interior at 720p with only two channels. For maximum evidentiary quality and coverage angles, the Vantrue N4 is clearly superior with triple-channel recording and higher resolution across all cameras.

Both cameras perform well in low light. The Vantrue N4's Sony STARVIS sensor excels in nighttime recording with infrared interior recording. The Garmin Tandem also has infrared night vision for its interior camera but the sensor quality is a step behind. For overnight parking surveillance or nighttime driving, the Vantrue captures more detail.

The Garmin Tandem is more compact and discreet with a cleaner design that blends into the windshield. The Vantrue N4 is noticeably larger due to housing three camera lenses. For drivers who want a low-profile dashcam that does not obstruct their view or draw attention, the Garmin's smaller form factor is a real advantage in a truck cab.

Garmin's companion app and Garmin Drive ecosystem provide a smoother experience for reviewing footage, downloading clips, and managing settings wirelessly. The Vantrue app is functional but less polished, and some drivers resort to removing the SD card for file transfer. Garmin's consumer electronics expertise shows in the software experience.

The Vantrue N4 supports up to 256GB microSD cards, which is essential given its triple-channel recording that consumes more storage. The Garmin Tandem supports up to 512GB but only records two channels. In practice, the Vantrue's three channels fill storage faster, but the larger card support helps compensate. Loop recording and parking mode are available on both.
