Question:
The GV-BLFC5800 alarm output's relay mode automatically reverts to "Bistable" from "Monostable" when the GV-BLFC5800 connects to the GV-VMS.

IP camera’s alarm output setting before connected to GV-VMS:
IP camera’s alarm output setting after connected to GV-VMS:
Answer:
Only the 'Bistable' mode is supported in order to allow proper software control when IP camera’s connected to the GV-VMS.
