I returned from a weeks holiday to find the car stating the 128gb memory card was full. On checking the footage there are literally hundreds of sentry clips of absolutely nothing. No people present no passing cars etc. No obvious triggers whatsoever. Is anyone else finding this? In this instance the car was parked at the back of three other cars on the drive effectively boxing it in for security purposes so even if passing cars on the road was triggering sentry I would have thought having another car in front would prevent the unnecessary alerts. Could a hedge moving in the wind create alerts? It will be annoying to have the card full every four weeks for no real reason.
