I would more than likely pick up a 4k cam instead. The only issues I ever had is they are picky with sd cards and even using a viofo card the cameras will act up and ask to format the card. Sometimes days apart others longer. I have tried doing a low level format and even use the gui app they recommend and it still happens.
I don't have a 4K because I use a lot of Parking Mode and need to make the external dashcam batteries (P8 and 2 Cellink Neo Ext) last a long time. I get roughly 60 hours capacity in Parking Mode. It never runs down too much for 15+ hours of parking Mode but still want to preserve as much capacity as possible so I don't have to drive a lot to recharge it.
I have a compact sedan (reputable Japanese manufacturer). The cig-lighter (15 amp fuse) in my car can't charge both the P8+2 Cellink Ext and a second P8 at same time. The fuse would blow. When one of the P8 set-ups shows 100% charged, then I can charge the seond P8 even with the other P8 still plugged into cig-lighter. Eventually I will have to hook one P8 to a fuse in the car's fuse box when the warranty expires.
I have 3 x P8 and can charge 2 of them indoors using the BBMyCar inverter. Charges up relatively quickly. One of the P8 is used to run the Viofo VS1 when parked. One is backup (can charge it indoors). One is the main battery used with the A229 Plus 3-channel.
If I parked in my own garage, I can turn the dashcam off. Then I would get a 4k cam right away. Why not get the best resolution possible. The front camera is very wide (140* FOV) and if the license plate is too far away like a few car lengths away while moving, a 4k will get me better resolution.
I had an issue with the 'please format' thing in the cold winter months (
we had an exceptionally long and cold winter in eastern Ontario) when the external batteries (
P8 + 2 x Cellink Neo Ext.)
would act up due to the cold temps.
This was in an underground parking garage.
Imagine if I had to park outdoors? I don't think the P8 would handle those temps. It would be outside the P8 recommeded operating temps.
The issue went away in the spring. I have 4 X Viofo 512 cards and two Sandisk Max Endurance.
