Did you draw the line and finished with a right click? Always close the line or area with right mouse click.i did but when i do save it says draw first
You need to reset the function, delete the rule, turn off IVS as selected. Restart the camera switch on IVS as function again and try to redraw the line.look i drawed then press save
The whole screen as tripwire? Maybe choose intrusion instead?i press draw target because i want the whole screen then save
Did you tried another browser? I know at least firefox browser have this issue with Dahua cameras?i choose intrusion and it does the same
i did intrusion draw target and bottom save and it says draw first
