The Nextbase 622GW supports a (separately purchased) rear-facing camera. He didn’t find the 4K resolution isn’t strictly necessary (it’s more important to just have a dash cam at all), but the resolution does make license plates more legible at a distance, which is a nice bit of insurance. Theoretically, you shouldn’t have to do this often, but it’s extremely nice at setup. Our tester found that support for Wi-Fi connection to the Nextbase app makes it much easier to mess with the settings of your cam and extract footage once its mounted, instead of contorting to press its buttons or take it down. Their flagship, the 622GW, is their true 4K recording unit with a full feature set plus image stabilization, slow-motion recording, extreme weather image processing, and Alexa and what3words integration. Nextbase has been building itself as one of the premier brands for dashcam systems. You’ve probably seen their advertisements, and for a good reason. In most cases, an extra microSD card is not included. Otherwise, recording 4K video may be inhibited due to inadequate microSD read and write speeds. Depending on which dash cam your purchase, it’s important to consult the owner’s manual for recommended microSD specifications and cards for best results. Pretty much all dash cams utilize microSD expandable storage on top of a small integrated memory unit. It can also record speed in the event you get wrongfully ticketed for speeding. In the event of an incident, dashcams with GPS will record the specific location of the incident if equipped with accident detection. But as mentioned above, most of the top-selling ones do, and GPS is important to have and is one of the pluses of having a dash cam. Not all dashcam units come with integrated GPS. Stick to the popular units and you’ll get all these neat features. Feature Setīecause of the saturated and competitive dash cam market, pretty much all the top-selling dash cams come with built-in Wi-Fi for smartphone connectivity, GPS for collision location and speed detection, gyroscopic sensors that can detect vehicle impacts and crashes, continuous “loop” video recording, supercapacitor (basically a fancier, more compact battery), intelligent parking sensing and monitoring, and expandable storage. Some dash cams feature all three views, but those tend to be the most expensive. Some rear-facing cameras are meant to record the passenger cabin for rideshare drivers, while others record the rear of the vehicle.

Number of Camerasīasic dash cams feature front-facing recorders while two-camera systems with a rear-facing unit could be had for not much more money. Thus, it’s important to consult the comments in customer feedback. Typically, the more expensive 4K dashcams have better and larger camera sensors, which result in a better quality video while the cheaper 4K units can sometimes “simulate” or upscale its imaging to provide a 4K-like picture in terms of pixel dimensions but may lack the actual definition quality. Otherwise, just aim for the 4K video dashcams. If you’re an enterprise and need the cheapest thing possible, that may be a fit for you. Still, some cheaper no-name units may just record 1080p. These days, however, the majority of the top-selling units record 4K video up front and 1080p out back, and they’re not particularly expensive either. Most if not all dash cameras record at least 1080p definition video. See all What to Look for in a Dash Cam Camera Quality
