I came across an issue with line crossing some months ago and thought it was a one off with one of my cameras or the NVR. Unfortunately I've now discovered the same problem exists in other cameras with the G1 and G1+M firmware.
The issue is that the A and B direction on the line crossing gets reversed and does not behave as expected. I first found this with a DS2CD2385-FWD-I running V5.6.x firmware connected to a DS7608NI-K2/8P NVR running 3.4.104 firmware.
I've now found the same issue...
