While video resolution could be your top priority, you can only maximize the security features of your 4K dash cam when you activate its parking mode feature - and both the Nextbase 622GW and VIOFO A139 Pro is equipped with this.
For the Nextbase 622GW, the Parking Mode includes Motion and Impact Detection that records any bump or physical movement on the vehicle while it is parked. It can also enter Super Slow Motion mode when you record video in 1080p at 120 frames per second.
However, most premium dash cams offer buffered parking mode that records before the event, during the event and after the event. Unfortunately, the 622GW records after the event only.
Having more recording modes than the 622GW, the VIOFO A139 Pro offers Auto Event Detection, Time Lapse, and Low Bitrate recordings. To activate these features, the A139 Pro must be connected through your car’s fuse box through a separate hardwiring kit, particularly VIOFO’s Type-C HK3-C and HK4 ACC hardwirings.
Going back to Nextbase, we discovered that the 622GW’s hardwire kit has an 11.V voltage cut-off setting. The safe voltage cut-off range is 12.0V to 12.2V, and setting it to 11.V is extremely hazardous to your car battery, causing it to drain, potentially require a jumpstart, and shorten its lifespan.
If you want to extend your parking modes, a battery pack, such as the BlackboxMyCar PowerCell 8, can also be used both for the Nextbase 622GW and VIOFO A139 Pro.
