Vehicle Notification

We installed our E340 Floodlight cam yesterday. Have received so far 45 false alerts of “vehicle spotted…” when the only vehicle in view at all…anywhere…is our own two vehicles parked on our drive. Help please…deciding whether to return camera as not fit for purpose.
Is the camera going to continue to notify me every few minutes that there is a vehicle parked on my drive? clearly either I have misunderstood the purpose of vehicle detection or something set up wrong. I assumed detection of vehicles functionality for a security camera would relate to moving vehicles? If not, what am I supposed to do? Not park at home?
