So I have a 64 Gb Stick formatted in Fat32 and A Folder inside called TeslaCam. I do see footage which is being recorded from the camera. My Question is seems like it is only keeping some minutes of footage and then start re-writing ? is that normal I thought it would record until the whole 64gb in my case is full and then start re-writing over the files. Becuase if it is only going to keep say like 30 mins or what ever the case is then I guess we can just get away with even 8gb of usb or something.
