Dahua tripwire multiple lines

[tigerwillow1]

I've got 4 tripwire lines set up on a camera. The NVR registers an event only when line 1 is crossed. When lines 2, 3, or 4 are crossed, they flash red on the video but don't show up as an event. Does this work ok for others? Is there some setup option I've missed?

they are all working for me, what camera and firmware version?

Thanks for the feedback, and I got more of my own overnight. When I drive a car through lines through lines 2, 3, and 4, they flash red but don't trigger an event. Last night some animals walked through the lines, and they did trigger events, and the lines sometimes did the red flash and sometimes didn't. It's looking like the red flashing and event trigger aren't 100% tied to each other, and it's not the line 2,3,4 issue that it looked like at first. Camera is an IPC-HFW4431M-I2 firmware 2.420.0000.21.R, Build Date: 2016-07-24.

I think the UI triggers the flashing regardless if something happens on the back end or not.. were the objects within the min and max sizes?

Someone else recently had a trip wire issue, and then solved it.

The flashing of the tripwire (blue to red) isn't 100% rock solid.
