Instead of a lithium battery (used in most dash cams), the T2 uses a capacitor power supply, which holds up better in extreme temperatures. But if you want extra insurance for hot and cold conditions, we recommend the Vantrue T2. We've had no heat-related problems with a couple of Nextbase models we used during several sizzling summer months in Southern California and New York. Because the Mini has only two physical buttons and no display, though, you have to use Garmin's smartphone app to view video, to adjust settings, and even just to aim the camera properly.
Still, it provides surprisingly good video quality for a 1080p model, and it's easy to pop on and off of its adhesive mount. About the size of a key fob, the Mini virtually disappears on the windshield. If you prefer a dash cam that people likely won't notice, we recommend the Garmin Dash Cam Mini, which is one of the smallest and most discreet models we've tested. And the rear-facing camera lets you see all passengers, even in total darkness. The front camera-recording in 1080p resolution-provides good overall image quality, although it's not as sharp as that of our single-cam picks.
If you want to record the interior of your car as you drive, we recommend the Vantrue N2 Pro, which has a camera that records the view in front of the car and another one that faces the interior, a handy setup for ride-for-hire drivers who want to document their passengers. As with most dual-cam models, the rear camera's image quality isn't as good as that of the front camera-it's less sharp, with duller colors and more contrast. Its front camera is surprisingly sharp for a 1080p model, and the video image has good color and contrast, as well as a decent dynamic range at night. For about half the price, or less, you can get the Papago GoSafe S810.
The best overall package would be to add Nextbase's optional rear camera to either the 522GW or the 422GW, but those combos can get pricey. If you want to record incidents behind your vehicle as well as in front of it, we recommend that you use a dual-cam model, which includes a second camera that's mounted to the rear window. It also usually costs less, and it lacks only the polarizing filter (although you can add an an optional one). It gives you the same excellent video image and most of the same features, but it's more compact, with a smaller touchscreen display (2.5 versus 3 inches). If you can't get the 522GW, or just want a slightly smaller model, we recommend the Nextbase 422GW. You can disable notifications at any time in your settings menu. Yes, it's more expensive than many competing models, but it provides the best dash-cam experience of any model we've tested. The 522GW can also pair with three different rear cams, giving you more versatility. The camera can integrate with Amazon's Alexa digital assistant, and a new Emergency SOS feature automatically summons emergency aid after a crash. The Nextbase phone app outshines competitors', and in addition to GPS, Bluetooth, and Wi-Fi, the 522GW gives you a polarizing filter to minimize annoying reflections. With its powered magnetic mount, the unit is easy to snap on and off, without having to mess with a cord. Using the 522GW's bright, responsive touchscreen to navigate menus and adjust settings is much easier than fiddling with the buttons of other models. The Nextbase 522GW Dash Cam produces a super-sharp 1440p (or Quad HD) video image that in our tests allowed us to clearly see details that were indecipherable with most other dash cams. It delivers the sharpest video we've seen, is the easiest to use, and has handy features that you don't get with most other dash cams. After researching more than 250 models and testing about 40, we've found that the best overall dash cam is the Nextbase 522GW. That's why a dash cam can be a critical aid if the unexpected happens. And as frightening as that may be, it can be just as distressing to be blamed for a crash that's not your fault.
