dashcam with apps which start to download footage automatically

[kngharv]

Dear all:
I am looking for specific features in a dashcam (app) in the order of priorities and importance:

1. I want my dashcam app automatically start to download the footage from the dashcam once the app is launched AND WiFi is connected to the dashcam (e.g. as soon as the app detects it is connected to the dashcam, it start to download the footage immediately)
2. ideally, i want my dashcam can both record and sync previous footage to my phone at the same time, assuming my phone will connect to the dashcam most of the time when I am in the car.
3. ideally, I want my dashcam stay powered up until the footage synchronization is complete (assuming it's hardwired or battery-power attached)

Is there a dashcam and its companion app on the market do at least No.1? If yes, are you aware of any dashcam app that does No.2 and/or No.3?
Thanks in advance
