Maybe I am just missing something simple, but if I am, it's not obvious how to do something I previousy thought would be simple.

I have numerous different models of Hikvision cameras, all of which have the option to set line crossing detection. Some are older cameras and some are newer. I also have an I series NVR.
What I am wanting to know is if it is possible to have a line detection event trigger recording of that event.

When I setup line crossing I can get the NVR to send me an email notification, which is accompanied by 3 incomplete image files (top 10% of image is okay, but the rest is blank), making that method next to useless.
However, no matter what I have tried, there is never a recorded event saved onto the NVR.

With motion detection enabled it all works as expected, but there are so many falsely triggered events (trees/leaves moving, shadows changing, etc.) that using motion detection is pretty useless too.
All I want to do is monitor a locked gate and get a notification and recording if anyone tries to open that gate.

So, what I would dearly like to know is if there is a way to have a line crossing event trigger a recording of that event.
If so, could someone please share their knowledge on this, as I have run out of options.
