Motion-Activated Lights in Floodlight Cam Wired Pro - distorted by Car Headlights?

I had a Floodlight Cam Wired Pro purchased recently and have it installed at the top of my Garage and pointing about 45 to 60 degree down to my driveway (by which the center point of the view is somehow the middle of the driveway). There should be a factory feature by activating the floodlight when there is a motion at "night". However, I noticed that when it is dark and I'm driving back to my Garage with my headlights on (or even I turn it off with only the daytime running lights on), the floodlight will not triggered on until my headlight goes into the Garage.I did a couple of test for it and with the following conclusions:-1. Floodlight will **NOT** triggered on until my headlight goes into the Garage.2. Floodlight will triggered on when I backup my car until I ran up to the middle of the driveway.3. Floodlight will triggered on when I walk up to the middle of the driveway.4. Floodlight will **NOT** triggered on when I walk thru the driveway with a flashlight.I just wonder if the floodlight sensor will "classified" it as daytime when there is a "light" detected at night and thus the floodlight will not triggered on as it should be ?? If that is the case, I do believe that it was a serious bugs and we are having a product that one of its major function is being "partially" eliminated.p.s. The camera is working well as it do capture everything while there is motion detected as per the settings.p.s.2 I did have my Motion-Activated Lights **ON**, and the motion Zones for Light was set as Max. Motion Sensitivity is a **2/3** of the setting, 3D motion detection is **ON** with 9m range, smart notification is **ON**.
