Welcome to the forum Pk3040.
To access your camera remotely in most cases you need a camera that have LTE, or the camera are within range of your home WIFI.
In general this mean the "Smart" cameras a few brands make.
Also normally dashcams going to parking guard, well they turn off their wifi if it have been on to conserve power, so very few have been able to mod / whip something together to just DL files from your camera in the car over wifi at home ( Viofo )
Some LTE enabled cameras, well in parking guard they also turn the LTE modem off to conserve power, and so you cant access it that way, at least it is that way with some cameras when they go to very deep sleep and use a radar to wake up the system, i think both blackvue and thinkware cameras do that.
Mind you the transfer speeds are slow LTE or 5 GHZ wifi, putting the memory card reader ( fast one on a fast USB port ) are much faster,,,, like 10 X
I personally just use wifi to do settings as my eyes can better deal with my 6" phone screen than the 1" that might be on the camera, newer cameras i have tested ( fast 5 GHZ wifi ) they still take 30 seconds to dl a single 330 MB file, the same file with the memory card in my card reader take 5 seconds.
A smart camera,,,, well to work the LTE function it might have, you also have to pay for a SIM card for it, and that in itself are also a additional monthly cost.
I am getting a smart / LTE camera soon VIA kickstarter,,,,,, might it is over a year delayed now, i am going to test the LTE part too, but i do think within a few months i will cancel that SIM card again.
Of course if your car are driving, then there will be no problem logging into a smart camera, and watch how your wife / kid drive, and also track where they are on a map.
I just mentioned the when parked issues as that is what many want.
