To set up go to Events/IVS and turn one on e.g. Tripwire – cam will reboot, then go back to Events/Motion Detection, click edit and enable and you will be able to draw the trip wires on the screen, there’s a limit of around 8 lines.
Alarms still come through as they did before with standard motion e.g. triggering SD card recording or coming through the control system driver. Note object counting is not an alarm so wont initiate anything.
