help stop Line detection picking up car lights

[phairplay]

Hi Guys,
I've recently had new IP HIKVISION DS-2CD2366G and I've set up Line Detection to pick up when our cars leave or return


My issue is, it seems to send notification when cars drive by at night and shine off my car windows.

can someone please tell me what i'm doing wrong

Why don't you back that line up to the middle or closer to the rear of the car?
