I have 3 camera’s pointing to my street and none of them are giving me false triggers with the zones, combo’d with sensitivity setting and experimenting with camera angles. All three requiring different settings. All are capturing the movement I want and need.
All I can say is keep experimenting, once you find that sweet spot then you should be done. But if its not, turn in an IT Ticket. They are more than likely going want a screenshot of your settings and the video. If you post it ‘here’ you may get a faster response.
