Mediocre, but it's tough on the environment.

TL;DR The 622GW records 4K front footage with image stabilization that community owners confirm reduces motion blur on rough roads. Night footage is documented as grainy in independent community comparisons, with plates unreadable at speed. Parking mode is trigger-only; the lithium-ion battery drains to near-zero within minutes without the separately sold hardwire cable. CE-only: no UL or ETL electrical safety certification. Carries a California Prop 65 warning.
The 622GW is a front-only dash cam with a 4K CMOS sensor, built-in circular polarizing filter to cut windshield glare, image stabilization confirmed by community owners as a real differentiator for daytime footage on rough roads, and what3words Emergency SOS geolocation. It also features Alexa voice control and dual-band WiFi for clip transfers. Plate legibility at highway speed has been documented as inconsistent in community footage comparisons; the 4K spec does not translate to benchmark-class performance on this dimension. Night vision earns consistent criticism across multiple independent owners: grainy footage and unreadable plates at speed are the recurring complaint. Community sources document SD card corruption starting around 12-18 months of normal use, with some owners reporting the same failure pattern on a warranty replacement unit. Parking mode is trigger-only; without the sold-separately hardwire cable, the battery fails in minutes.
Best match for daytime-only drivers on unpaved or rough roads where image stabilization is the primary priority, and who plan to purchase the hardwire cable from day one rather than relying on battery-powered parking mode. Skip it if night footage quality, long-term reliability past 18 months, or functional parking-lot protection are priorities; community footage data puts competing units at similar price points ahead on all three.
Lithium-ion buffer battery; standard Best Buy and Call2Recycle e-waste drop-off applies at end of life. No Nextbase US take-back program documented. CE-marked for UK/EU compliance; no independent UL or ETL electrical safety certification. Carries a California Prop 65 warning (lead/phthalates in housing/cables, standard electronics disclosure). No chemical exposure during normal installation or use.
The 622GW has trigger-only motion and impact detection for parking mode, but the lithium-ion battery drains to near-zero within minutes of the engine shutting off. Multiple community owners report it becomes non-functional almost immediately without a hardwire connection. Sustained parking monitoring requires the separately purchased Nextbase Constant Power Cable.
The 622GW records at 4K UHD (3840x2160 at 30fps), but community footage comparisons show real-world plate legibility at highway speed falls short of what that resolution implies. Night footage in particular has been documented as grainy by multiple independent owners, with plates unreadable at speed in low-light conditions.
What3words divides the world into 3-meter squares, each with a unique three-word address. When Emergency SOS is triggered on the 622GW, it transmits the what3words address of the vehicle's location to emergency services, giving a more precise location indicator than GPS coordinates alone in rural or unfamiliar areas.
The Amazon listing for Nextbase 622GW Dash Cam carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including electronics with wiring, solder joints, or plastic/metal housings — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive electronics product, Nextbase 622GW Dash Cam has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
