I visited BlackVue's site and do see they offer the cloud service and that it does require wifi connection. At home should be fine, although its parked in the garage where I have a security cam, but my thought is being parked at a mall or at the airport and wanting to check in on the car or get alert if tampered with or moving activity caught. The wifi in the car isn't active unless the car is on from what I know. I looked at the Owlcam after you provided the link, but it doesn't seem to be as good as quality as what the Blackvue is. Be nice if the Blackvue offerered the cell service.
Agreed, the OwlCam was very tempting for that feature and it was on my short list. But as you can see I decided the higher res on the Blackvue was more important to me. Typically this car doesn't sit in places where I think it will be burglarized. For me parking lot damage at the office parking garage is a bigger concern. Someone scraped my truck rear quarter with their bumper there and didn't leave a note. Unfortunately I had the camera parked facing the wall so I never got a view of their car.
