I own 412GW and 512GW. I don't find NextBase parking mode useful for anything in the real world. It drains the tiny battery in zero time (especially if it is cold weather). The unit only starts recording a AFTER an event has happened (seconds later, and only after a hard bump). But it starts recording every time we close the doors. A nice feature on the paper, but it doesn't really work in everyday real life.
I think 1440p@30fps can be preferred if you just want some nice big wide footages of your road-trip, but based on my own real life experiences I have found that 1080p@60fps generally works best for pictures that can be used to e.g. see the face of the offending driver (for Police identification purpose) - and/or the license plate under low light conditions. 60fps give me less blur on each individual picture and twice the amount of pictures to study. In every case I have needed to use my videos for identification purposes, at least one of the cars has been moving (=more blur with 30fps than 60fps). So in my opinion and experience 60fps is generally best option if footages is to be used for security / identification purposes. However...Your mileage may vary.
