I was looking at Blackvue after Barrie's (not his fault) smash. They have a cloud thing. I only skimmed the website but it looks like the camera has a sim card so data is uploaded to that there cloud thingy so you can, should you so wish, manage, delete / format the memory card remotely. In case, you know, you want to free up some space or something. Prices can be eye-watering, but cheaper options are available.
Maybe I should look properly. To be honest, they pish me off, all these ***** uploading images of people driving just about over the limit but not really in a bad way. Is nothing sacred? Though I do agree that proving you weren't to blame could come in handy Unless you were.
