![]() If the memory lasted forever, well then you could make do with just a 8GB card which would just store the last 30 minutes of driving, BUT ! then you do not have room for locked event files for instance as those the camera can not overwrite so creating those manual or automatic and you just end up with 0 memory for the regular driving video. Memory card life time are set in full write cycles, so while in theory you could make do with a 32 GB card and the few hours it hold, then as it is a smaller card it will also burn thru write cycles faster than a larger memory card, so for this reason a larger memory card is also preferred. So it is a compromise getting just enough detail to provide useful evidence in case of a alteration, and memory space.Ī 1080p dashcam will generate about 350 MB files every 3 minute ( from each camera ) if you record sweet 4K using a good action camera you will probably see around 3000 MB for every 3 minutes you film. ![]() In regard to the concept itself, a dashcam do record video, but the people that make scenic drive videos, i am sure none of them use a dashcam for that as really aside for it being video it is something else.Ī proper nice drive video, you do not have dashboard or A pillars in the frame, and you would record on a higher bitrate camera as you will want the best possible detail amount, and a dashcam record in a very moderate bitrate VS a proper video camera that have 4 X higher bitrate, and as a consequence of that also generate about 4X larger files.Ī dashcam is a compromise camera, it use a lesser bitrate and so image quality in order to generate as small as possible files and put as much as possible video on a memory card. So you can use stops to offload footage to a larger means of storage like a laptop harddrive. So the best solution is to pull over now and then, which i assume you are going to do anyway, cuz i have tried to drive far ( +1000 km ) in one go and that is just not cool with no stops. Now if you are driving across the states, and do so fast, meaning several drivers taking shifts, and still we are not talking cannonball run, then it will probably take more time than a single 512 GB card can provide. I think that ATM most dashcams still top out at 128GB memory card size, some do officially support 256GB and very few are tested and will support 512 GB You would still need to offload your video to a hard drive but a camcorder may be a more suitable device for this purpose. While you may well be able to do what you have in mind with a dash cam that can hold a 512 GB memory card (and some members have recently also been experimenting with newly available 1 TB microSD cards), you "might" be better off with a dedicated video camera mounted on your dashboard, such as a small camcorder, as these are specifically designed for lengthy recording sessions. Manufacturers don't build them this way because only a tiny fraction of users would want to use dash cams in this manner. In theory, it is doable but it is cumbersome. ![]() Dash cams can be set to record full time but they will stop recording when the memory card becomes full.ĭash cams were never really designed for recording a full cross country multi-day journey like you have in mind although occasionally a few people express an interest in doing this and some have tried it. ![]() When your memory card becomes full, it will record over the first clips to make room for new ones. ![]() The primary purpose of a dash cam is to preserve evidence during a car accident or other road mishap and so they are generally set to record in short clips called "loops" ranging from 1 to 5 minutes. ![]()
