New, Heres my Requirements

[Spades68]

1.) Record 3 Channels (Front/Rear/Interior)
2.) Secondary external recording off-load to a external portable SSD/HDD/or another microSD (such as my center dash console takes a 128gb microSD card and I would like to move the footage to that automatically which connects to my phone)
3.) Parking recording (if I need an external battery to keep it powered, I'll buy that too)

I am very adamant about having a secondary off-load location inside the vehicle in-case the vehicle's dash-cam is stolen or the card is removed by someone. 3 Channels sounds non-standard so I am willing to purchase different camera's to get this setup to work. Its just too easy to rip the camera out of the vehicle and then you are left with 0 evidence.

Nothing out there right now that does what you want

Ditto what jokiin said, and they’re an expert. I’m new to the site but have been doing a ton of research to gain more knowledge since joining here and what you want isn’t out there in a neat package.

There are external battery packs to keep a cam recording hours and hours after shutting the car off, here’s a new one (that I have) for example: https://www.blackboxmycar.com/products/cellink-battery-neo?variant=5073937203237

I have never seen a 3ch system. The above site has a 4 channel system but it is just 2 separate 2channel systems with 2 front cams (front and back) and 2 rear cams to cover the sides.

Some Blackvue cams have ‘Blackvue over the cloud’ that has features such as video backup/auto upload but honestly I find the whole thing confusing and it needs an internet connection to work so unless one wants to hook up a mobile hotspot that stays active all the time while the car is turned off, it isn’t of much use, at least imo. Research it more though if you would like to. https://www.blackvue.com/blackvue-over-the-cloud/
