When it comes to video resolution, both the VIOFO WM1 and the Nextbase 522GW record in 2K QHD and sport a 5-megapixel Sony STARVIS IMX335 image sensor so there’s nothing much to compare with these two. Both deliver crisp details of the road ahead as both are single-channel cameras, although you can buy a separate secondary for the 522GW.
Price-wise? The VIOFO WM1 is less expensive, despite having most of the same functionality (and higher safety features) as the Nextbase 522GW. If you would notice, the price of the 522GW is really expensive - even higher than VIOFO's newest 4K dash cam with Sony STARVIS 2, the A139 Pro.
Talking about its form factors, the WM1 is built sleeker and discreetly which is suitable for all types of vehicles. The Nextbase 522GW, on the other hand, is larger and has a 3-inch screen.
Despite its small size, the WM1's Parking Mode is more advanced than the Nextbase 522GW's because it includes Buffered Recording. The 522GW's hardwiring and voltage cutoff are also dangerous at 11.0V, which is risky for your car battery.
And speaking of batteries, the Nextbase 522GW is equipped with a lithium ion battery. This is a standard feature of dash cams, and we're surprised that Nextbase, a premium brand, doesn't have a supercapacitor like the WM1. If you live in warmer states or provinces, the 522GW is not designed to withstand extreme temperatures, but you can certainly rely on the WM1 because of its heat resistance, and guaranteed longevity.
