I just want to make sure if something happens I have the video saved and I figured if it were backed up to a cloud service I would be covered either way. Is that unrealistic? Is there a better way. I want to cover front, rear and inside, do I need all that?
The 3 channel dashcams seem to be more suited for Uber drivers and the like if something happens inside their car, although I'm sure some people who are not paid drivers decide they want interior coverage as well.
And you are not at all being unrealistic about your desire for cloud features with your dashcam. There are many good reasons for using the cloud. One good reason for using cloud features is that if something happens to your car and someone physically removes your dashcam and sd card, you could have the video saved on the cloud.
However, one would not want to automatically backup everything recorded on the dashcam to the cloud. Data consumption and costs would be too much.
If you had a serious impact (g-sensor triggered event) you would want that "automatically saved to the cloud". And both of the manufacturers I mentioned above will do that for you.
Another great reason for having the use of cloud features is if anything happens to your car while parked, you will receive a push-notification on your phone immediately. You won't have to wait until you go out to your car hours later or the next morning.
And another good feature with the cloud is you would be able to view "live coverage" remotely of what's happening at your car at any moment from anywhere by using your phone or computer.
In addition to buying a dashcam with cloud features, it is "very important" to buy from a company that offers "good customer support". Unfortunately, it seems like most dashcam companies do not provide adequate support. And believe me, at some point, you will need support! - Good luck!
